Uzun E, Erkilic S. Diagnostic accuracy of Thinprep® in cervical lymph node aspiration: Assessment according to the Sydney system. Diagn Cytopathol 2022; 50:253-262. [PMID: 35148033 DOI: 10.1002/dc.24943] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Revised: 01/20/2022] [Accepted: 01/26/2022] [Indexed: 11/07/2022]
Abstract
BACKGROUND Fine-needle aspiration cytology (FNAC) is a reliable technique that has been used for many years in lymphadenopathy diagnosis. Although conventional smear is the standard approach in FNAC, liquid-based cytology (LBC) is accepted as an alternative method. Reporting standardization is a significant gap in fine-needle aspiration cytology, leading to failure in pathologist-clinician dialog and interobserver variability. In 2020, an expert panel proposed the Sydney system for classifying and reporting lymph node aspiration cytology. This study aimed to evaluate the diagnostic accuracy of LBC in lymph node aspiration cytology under the guidance of the Sydney system. METHODS Five hundred-four LBC samples were reevaluated and classified according to the Sydney system. Of these, n = 24 were categorized as L1-inadequate/non-diagnostic, n = 283 as L2-benign, n = 36 as L3- atypical cells of undetermined significance/atypical lymphoid cells of uncertain significance (AUS/ALUS), n = 48 as L4-suspicious, and n = 113 as L5-malignant. Four hundred-one samples were histopathologically confirmed. The diagnostic accuracy of LBC and the risk of malignancy for each Sydney category were calculated. RESULTS The results were as follows: sensitivity 98.97%; specificity 98.60%; positive predictive value 94.80%; negative predictive value 99.29%; and overall diagnostic accuracy 98.75%. The ROM was 16.6% for L1, 0.7% for L2, 88.8% for L3, and 100% for L4 and L5. CONCLUSION LBC is suitable for use in lymph node aspiration under the guidance of the Sydney system and has high diagnostic accuracy. Future comprehensive studies will increase the applicability of the Sydney system and minimize interobserver variability.

Fine-Needle Aspiration Diagnosis of Lymphoma Based on Cytomorphology Alone: How Accurate is it? - A Cyto-Histopathology Correlative Study. J Cytol 2021; 38:164-170. [PMID: 34703094 PMCID: PMC8489699 DOI: 10.4103/joc.joc_217_20] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Revised: 06/26/2021] [Accepted: 08/18/2021] [Indexed: 12/29/2022] Open
Abstract
Context: Fine-needle aspiration cytology (FNAC) is a rapid and accurate first-line diagnostic modality in lymphadenopathy. Aims: To determine the utility of FNAC for the diagnosis of lymphoma and highlight the various pitfalls in morphological interpretation. Settings and Design: This was a retrospective study of 3 years duration in which cytology diagnosis was compared with the follow-up histopathology diagnosis wherever available. Results: A cytodiagnosis of lymphoma was made in a total of 868 cases (2.8%) out of nearly 33,000 FNAC performed during the study period; 556 (64.1%) cases were diagnosed as non-Hodgkin lymphoma (NHL), 198 (22.8%) as Hodgkin lymphoma (HL), and in 114 (13.1%) cases, a cytological diagnosis of lymphoma without further categorization was given. Histopathological reports were available in 348 cases, with an overall concordance rate of 93.1% (324), which was slightly higher in the HL cases (95.8%) as compared to NHL (91.7%). Twenty-four cases (6.9%) showed discordant cytological diagnosis with subsequent histopathology. The main reasons for the erroneous diagnosis were the over-interpretation of the germinal center cells as atypical lymphoid cells, over-interpretation of immunoblasts with prominent nucleoli as Hodgkin cells, and sheets of monomorphic lymphoid cells interpreted as low-grade lymphoma. Conclusion: Cytomorphology alone can make a correct basic diagnosis of lymphoma with a high degree of accuracy. The errors in interpretation can be further reduced by careful attention to the diagnostic pitfalls and common differential diagnoses.

[PMID: 34004059 DOI: 10.1002/dc.24800] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Revised: 04/12/2021] [Accepted: 05/08/2021] [Indexed: 11/12/2022]
Abstract
BACKGROUND Fine-needle aspiration cytology (FNAC) has become one of the most useful modalities for diagnosis and staging of lymphoma. However, diagnostic accuracy of this technique has been reported with varying results across several studies around the world. Hence, this meta-analysis was done to assess the accuracy of FNAC for lymphoma diagnosis. METHODS We conducted a systematic search for all studies reporting the diagnostic accuracy of FNAC for lymphoma in the databases of PubMed Central, MEDLINE, EMBASE, MEDLINE, SCOPUS and Cochrane library from inception till January 2021. Meta-analysis was performed using STATA software "midas" package. RESULTS Forty-seven studies with 7268 patients were included. The pooled sensitivity and specificity of FNAC for diagnosing lymphoma were 93% (95% CI, 90%-95%) and 97% (95% CI, 95%-98%), respectively. Likelihood ratio positive was 33.5 (95% CI, 18.5-60.7) and likelihood ratio negative was 0.07 (0.05-0.11) making the technique to occupy the left upper quadrant in LR scattergram indicating that FNAC can be used for confirmation and exclusion. There was significant heterogeneity with significant chi-square test and I2 statistic >75%. There was significant publication bias as per Deek's test and funnel plot. CONCLUSION To summarize, our study found that FNAC has a vital role as a diagnostic tool for lymphoma with higher sensitivity and specificity. Further studies assessing the accuracy of FNAC on specific types of lymphoma is required.

Abstract
Neck masses, frequently encountered by physicians, comprise a vast range of diagnoses, with malignancy being the greatest concern. Calcifying fibrous pseudotumor (CFP) is a rare lesion with unknown pathogenesis, characterized pathologically by a predominance of abundant hyalinized collagenous tissue with focal lymphoplasmacytic infiltrate and psammomatous or dystrophic calcifications. We present the case of a 29-year-old woman who presented with a 4-cm left neck mass, accompanied by constitutional symptoms of vague weakness and lethargy. After the lesion failed to respond to a course of antibiotic therapy, fine-needle aspiration was performed, the pathology of which was indeterminate. The concern was that the lesion was a lymphoproliferative disorder–further workup was performed. CT of the chest, abdomen, and pelvis revealed no evidence of adenopathy or neoplasms. Subsequently, an incisional biopsy was performed, suggesting a diagnosis of CFP. Magnetic resonance imaging with contrast, performed to delineate the anatomy, revealed the lesion in the left neck, deep to the left clavicle, that extended superiorly into the supraclavicular fossa. Complete surgical removal of the lesion was successfully performed, with immunophenotyping confirming the initial diagnosis of CFP. We present a case report of cervical CFP, discuss the approach to neck masses, and review the recent literature on this rare, benign entity.

Abstract
BACKGROUND The evaluation of lymph nodes (LN) by fine-needle aspiration cytology (FNAC) is routinely used in many institutions but it is not uniformly accepted mainly because of the lack of guidelines and a cytopathological diagnostic classification. A committee of cytopathologists has developed a system of performance, classification, and reporting for LN-FNAC. METHODS The committee members prepared a document that has circulated among them five times; the final text has been approved by all the participants. It is based on a review of the international literature and on the expertise of the members. The system integrates clinical and imaging data with cytopathological features and ancillary techniques. The project has received the endorsement and patronage of the International Academy of Cytology and the European Federation of the Cytology Societies. RESULTS Clinical, imaging, and serological data of lymphadenopathies, indications for LN-FNAC, technical procedures, and ancillary techniques are evaluated with specific recommendations. The reporting system includes two diagnostic levels. The first should provide basic diagnostic information and includes five categories: inadequate/insufficient, benign, atypical lymphoid cells of undetermined/uncertain significance, suspicious, and malignant. For each category, specific recommendations are provided. The second diagnostic level, when achievable, should produce the identification of specific benign or malignant entities and additional information by utilizing ancillary testing. CONCLUSION The authors believe that the introduction of this system for performing and reporting LN-FNAC may improve the quality of the procedure, the report, and the communication between cytopathologists and the clinicians. This system may lead to a greater acceptance and utilization of LN-FNAC and to a better interdisciplinary understanding of the results of this procedure.

Flow cytometric analysis of fine needle aspirates is affected by tumor subtype, but not by anatomic location nor technique. Diagn Cytopathol 2020; 48:538-546. [PMID: 32212260 DOI: 10.1002/dc.24417] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Revised: 02/18/2020] [Accepted: 03/11/2020] [Indexed: 11/10/2022]
Abstract
BACKGROUND Current clinical practices are shifting towards utilizing less invasive biopsy techniques, including fine needle aspiration (FNA) and needle core biopsies. If a patient has a suspected hematologic malignancy, a portion of the FNA sample is typically submitted for flow cytometry (FC) analysis, providing valuable immunophenotypic data. METHODS FNA specimens were identified via a pathology database search. All cases were morphologic evaluated and a subset of cases were analyzed by FC. RESULTS 245 hematologic FNA specimens were identified; 84% of these cases had an adequate number of cells for FC analysis, and an unequivocal morphologic diagnosis (benign or malignant) was rendered in 85%. The percentage of cases with an unequivocal diagnosis was statistically significantly higher in those with associated FC than with those without FC (90% vs 58%). Neither FNA technique nor anatomic site affected the likelihood of obtaining an adequate sample for FC analysis and/or rendering a definitive morphologic or unequivocal FC diagnosis. Likewise, tumor subtype did not affect the likelihood of acquiring enough cells for FC analysis, but occasionally resulted in equivocal FC diagnoses or discordant FNA and FC diagnoses. Aggressive B-cell lymphomas and Hodgkin lymphomas were significantly less likely to be detected by FC as compared to low-grade B-cell lymphomas. Discrepancies between FNA and FC diagnoses occurred in 13% of cases. The majority of discrepancies (78%) included FC false negatives, while only 22% of cases had atypical or positive FC with negative FNA. CONCLUSIONS FNA with associated FC is a powerful diagnostic technique; however, lymphoma subtype may affect diagnostic sensitivity by FC, and therefore, discordant FNA and FC results should be interpreted with caution.

Abstract
An 8-year-old Shih Tzu, a 5-year-old Maltese, and a 10-year-old Maltese presented with conjunctival hyperemia and peripheral corneal edema. Severe conjunctival thickening with varying degrees of corneal extension was observed. Cytological examination showed many large lymphocytes with malignant changes in the conjunctiva which was consistent with findings in fine-needle aspiration samples taken from regional lymph nodes. They were diagnosed as having Stage V multicentric lymphoma. When conjunctival thickening is observed in canine patients with multicentric lymphoma, conjunctival metastasis with infiltration of neoplastic lymphoid cells should be included in the differential diagnosis.

Abstract
Lymphadenopathy can be due to multitude of causes. Owing to the high prevalence of infectious diseases in India, and malignancy being a life threatening cause for lymphadenopathy; accurate diagnosis is important in preventing delay or misdiagnosis and in improving patient care, thereby increasing longevity with quality. Fine needle aspiration cytology (FNAC) is the first line investigation commonly done. Should the doctor be contented with the benign FNAC or is a lymph node biopsy needed in this age? The aims of this study are the following: (1) to study the spectral pattern of lymph node biopsies done in a surgical oncology unit of tertiary care centre, (2) to assess the yield of malignant cases from lymph node biopsy and (3) to compare the reliability of benign FNAC with lymph node biopsy. Cross-sectional study of 114 cases that underwent lymph node biopsy during the year 2014, at the Surgical Oncology Department of St. John's Medical College Hospital, Bangalore. Lymph node biopsies were done in the outpatient department (OPD) under local anaesthesia or in the operation theatre under local anaesthesia/monitored anaesthesia care based on the clinical condition of the patient. Regional lymph node dissections, central node biopsy, patients with known case of malignancy were excluded. Specimen sent for histopathological study and immunohistochemistry (IHC) done when needed. 58.8% were males among study population, age ranging from 15 to 80 years, 57% cervical and 29.8% axillary lymph node biopsies done. Sixty-seven percent (67%) of biopsies done in OPD. Thirty-three percent (33%) of biopsies in the operation theatre among which 60.5% under local anaesthesia only. 35.1% cases were reactive hyperplasia, 24.6% lymphomas with non-Hodgkin's lymphoma being the commonest, 13.2% metastatic disease with adenocarcinoma being the commonest. 72.7% of the supraclavicular nodes were malignant. 47.4% of subjects had prior FNAC of the lymph node. Twenty-five percent (25%) of the reactive hyperplasia's on FNAC (p < 0.0001), 33.3% of inadequate FNAC (p = 0.003) and 75% of atypical cells in FNAC turned to be malignant on lymph node biopsy with a discordance rate of 20.3%. Lymph node size didn't correlate with neoplasm. In our study, benign cytologies were malignant on biopsy and statistically significant. Lymph node biopsies are reliable in detecting malignancy and subtyping of the disease. In the presence of strong clinical suspicion, lymph node biopsy is essential even when the FNAC is promisingly benign in a country with limited resources. Lymph node biopsy can be safely done in OPD under local anaesthesia at a lower cost, resulting in a reliable diagnosis thereby improving patient care.

Abstract
Kimura disease is a benign rare chronic inflammatory disorder of unknown aetiology. This disease is mainly endemic in Asia, although cases have also been reported in Europe and America. We describe a case in a 34-year-old Chinese man presenting with severe eosinophilia and multiple lymphadenopathy. Since our initial aim was to rule out the diagnosis of lymphoma, and given the limitations of our laboratory, we decided to perform an excision of one of the cervical lymph nodes. The histological diagnosis was consistent with Kimura disease. We review the epidemiology, the aetiology and clinical features of this entity.

Abstract
Background: In this paper, we have compared the cytomorphologic characteristics of liquid-based preparation (LBP) [SurePath (SP)] cytology and conventional smear (CP) preparations on fine-needle aspiration (FNAC) material by a semi-quantitative scoring system for cases of lymphadenopathy. Materials and Methods: In this prospective study, a total of 52 consecutive cases of FNAC of lymphadenopathy were included. The first pass was used for CP followed by LBP with the help of SP technique. The smears were independently compared and assessed by two observers (PS and PD). Results: The semiquantitative grading was compared in two groups by Wilcoxon signed-rank test. The background information, cell architecture, pleomorphism, nuclear and cytoplasmic details, and three-dimensional structures were significantly different in LBP and CP smears. Conclusions: Liquid-based cytology (LBC) is a relatively simple technique, which exhibits good nuclear and cytoplasmic details with the absence of obscuring background material. Even the number of slides and area per slide to be screened were less than the conventional preparation but caution must be applied to interpret the slides and secure a diagnosis, especially if LBC is the first and only method applied for diagnosis.

Abstract
Anterior mediastinal masses are relatively uncommon, include a wide variety of entities, and often pose a diagnostic challenge for clinicians. In this article, available data is assembled in a clinically oriented manner to develop a structured approach to evaluation of these patients. Attention to age and gender, combined with identification of certain radiographic and clinical characteristics, allows a presumptive diagnosis to be established in most patients. This structure efficiently guides what additional workup is needed.

Abstract
Liquid-based Cytology (LBC) consists of immediate wet cell fixation with automated slide preparation. We applied LBC, cell block (CB) and immunocytochemistry to diagnose canine lymphoma and compare results with conventional cytology. Samples from enlarged lymph nodes of 18 dogs were collected and fixed in preservative solution for automated slide preparation (LBC), CB inclusion and immunophenotyping. Two CB techniques were tested: fixed sediment method (FSM) and agar method (AM). Anti-CD79a, anti-Pax5, anti-CD3 and anti-Ki67 were used in immunocytochemistry. LBC smears showed better nuclear and nucleolar definition, without cell superposition, but presented smaller cell size and worse cytoplasmic definition. FSM showed consistent cellular groups and were employed for immunocytochemistry, while AM CBs presented sparse groups of lymphocytes, with compromised analysis. Anti-Pax-5 allowed B-cell identification, both in reactive and neoplastic lymph nodes. Our preliminary report suggests that LBC and FSM together may be promising tools to improve lymphoma diagnosis through fine-needle aspiration.

Abstract
Lymphoma is the most common hematologic malignancy and represents approximately 5.3% of all cancers. The World Health Organization published a revised classification scheme in 2008 that groups lymphomas by cell type and molecular, cytogenetic, and phenotypic characteristics. Most lymphomas affect the thorax at some stage during the course of the disease. Affected structures within the chest may include the lungs, mediastinum, pleura, and chest wall, and lymphomas may originate from these sites as primary malignancies or secondarily involve these structures after arising from other intrathoracic or extrathoracic sources. Pulmonary lymphomas are classified into one of four types: primary pulmonary lymphoma, secondary pulmonary lymphoma, acquired immunodeficiency syndrome-related lymphoma, and post-transplantation lymphoproliferative disorders. Although pulmonary lymphomas may produce a myriad of diverse findings within the lungs, specific individual features or combinations of features can be used, in combination with secondary manifestations of the disease such as involvement of the mediastinum, pleura, and chest wall, to narrow the differential diagnosis. While findings of thoracic lymphoma may be evident on chest radiography, computed tomography has traditionally been the imaging modality used to evaluate the disease and effectively demonstrates the extent of intrathoracic involvement and the presence and extent of extrathoracic spread. However, additional modalities such as magnetic resonance imaging of the thorax and (18)F-FDG PET/CT have emerged in recent years and are complementary to CT in the evaluation of patients with lymphoma. Thoracic MRI is useful in assessing vascular, cardiac, and chest wall involvement, and PET/CT is more accurate in the overall staging of lymphoma than CT and can be used to evaluate treatment response.

Abstract
BACKGROUND The retroperitoneal space contains various organs which can be affected by various non-neoplastic and neoplastic pathological processes. A diagnosis of these retroperitoneal lesions is often difficult. Fine-needle aspiration cytology (FNAC) under image guidance is now becoming an effective tool for the initial evaluation of retroperitoneal lesions. OBJECTIVE The present study was undertaken to evaluate the role of ultrasound-guided FNAC in the diagnosis of retroperitoneal lesions in comparison to histopathology and to assess the probable causes of failure in cases of pitfalls in cytodiagnosis. MATERIALS AND METHODS During the study period of 5 years, a total of 104 cases of retroperitoneal lesions were aspirated under USG guidance. Seven cases yielded inadequate material, the remaining 97 cases were included in the study group. RESULTS Out of 97 cases, the kidney was the most common organ aspirated (27 cases; 27.8%). Malignant lesions (68 cases; 70.1%) were much more frequent than benign or non-neoplastic lesions (29 cases; 29.9%). Tuberculosis was the most common non-malignant lesion (14 cases) and renal cell carcinoma was the most frequent malignant lesion encountered (15 cases). In 5 cases (7.9%), the histological diagnosis showed inconsistent results in comparison to cytodiagnosis. CONCLUSION USG-guided FNAC is a safe, rapid, relatively cheap and fairly accurate procedure for the assessment of retroperitoneal lesions.

Abstract
Fine needle aspiration (FNA) cytology is well accepted as a safe, reliable, minimal invasive and cost-effective method for diagnosis of salivary gland lesions. This study evaluated the accuracy and diagnostic performance of FNA cytology in Thailand. A consecutive series of 290 samples from 246 patients during January 2001-December 2009 were evaluated from the archive of the Anatomical Pathology Department of our institution and 133 specimens were verified by histopathologic diagnoses, obtained with material from surgical excision or biopsy. Cytologic diagnoses classified as unsatisfactory, benign, suspicious for malignancy and malignant were compared with the histopathological findings. Among the 133 satisfactory specimens, the anatomic sites were 70 (52.6%) parotid glands and 63 (47.4 %) submandibular glands. FNA cytological diagnoses showed benign lesions in 119 cases (89.5 %), suspicious for malignancy in 3 cases (2.2 %) and malignant in 11 cases (8.3%). From the subsequent histopathologic diagnoses, 3/133 cases of benign cytology turned out to be malignant lesions, the false negative rate being 2.2 % and 1/133 case of malignant cytology turned out to be a benign lesion, giving a false positive rate was 0.8%. The overall accuracy, sensitivity, specificity, positive predictive value and negative predictive value were 97.0% (95% CI, 70.6%-99.4%), 81.3% (95% CI, 54.4%-96.0%), 99.1% (95% CI, 95.4%-100%), 92.9% (95% CI, 66.1%-99.8), 97.5% (95% CI, 92.8%-99.5%), respectively. This study indicated that FNA cytology of salivary gland is a reliable and highly accurate diagnostic method for diagnosis of salivary gland lesions. It not only provides preoperative diagnosis for therapeutic management but also can prevent unnecessary surgery.

Abstract
Primary breast lymphomas are uncommon. All reported primary breast lymphomas were in the breast parenchyma. Here we reported the first case of primary nipple lymphoma in a 76-year-old woman initially diagnosed using a modified fine-needle aspiration method. The aspirated material by this method had yielded adequate material for both cytomorphologic and flowcytometric analysis, as well as for molecular analysis of light chain rearrangement. In smears the atypical lymphocytes were predominantly middle-sized with irregular nuclei. Scattered large centroblast or immunoblast-like cells, a few reactive lymphocytes,histocytes, and few plasma cells were also observed. These findings suggested a low-grade lymphoma that was further confirmed by flow cytometry (CD19+/CD3-, positive for cytoplasmic kappa light chain but negative for lambda light chain) and molecular analysis (monoclonal rearrangement of immunoglobulin kappa chain). Immunohistochemical stains performed on the excised specimen showed that the tumor cells were positive forCD20 and CD79a but negative for cytokeratin, CD3, CD5,CD10, CD23, CD43, CD45RO, bcl-6, and cyclin-D1. The Ki-67 proliferation index was less than 20%. Taking these together, the case was diagnosed as a primary MALT lymphoma of the nipple.FNA usually provides a better cell morphology than tissue sections, but pathologists have to face the sampling error and lack of immunophenotype information when subtyping lymphoma issues using FNA. With the help of flow cytometry and molecular analysis, more and more trials have proved the accuracy of FNA in diagnosis of lymphomas. Therefore, FNA could play an informative and diagnostic role in diagnosis of lymphoma

Abstract
CONTEXT Surgical pathology is unavailable in most of sub-Saharan Africa because of equipment costs and lack of expertise. Cytopathology is an inexpensive and reliable alternative. OBJECTIVE To explore the utility of cytopathology in a rural hospital setting in Africa. DESIGN A cytopathologist and a pathology resident from Calgary, Alberta, Canada, went to Cameroon to provide a cytopathology service at the Banso Baptist Hospital. Both performed the fine-needle aspiration procedures. Direct smears were fixed in alcohol and stained with hematoxylin-eosin. Surgical specimens subsequently obtained from the patients were processed and reported at Calgary Laboratory Services, Canada. The histopathologic diagnoses were the gold standard for determining the accuracy of the cytologic diagnoses. RESULTS Fifty-nine patients were examined during a 5-week period, 33 females (56%) and 26 males (44%). Sixteen (27%) were known to be HIV positive. Forty-four fine-needle aspiration procedures were performed for 43 patients (73%). The cost of each procedure was approximately US $10. Head and neck and breast were the sites most frequently sampled for aspirates. Cervical smears from 5 patients were also assessed, as were 8 fluid specimens and 2 touch preparations of prostatic core biopsies. The most frequent diagnoses for malignancy were carcinoma and lymphoma. Tuberculous lymphadenitis was diagnosed in 6 patients, 4 of whom were HIV positive. Surgical specimens were received from 18 patients (30%). Cytohistologic and clinicopathologic correlation revealed 1 false-positive (1.6%) and 1 false-negative (1.6%) diagnosis. CONCLUSION Cytopathology is a reliable alternative for tissue diagnosis in low-resource settings.

Abstract
BACKGROUND Fine-needle aspiration (FNA) has been used in the evaluation of lymphadenopathy for a long time and is highly reliable in the identification of metastatic malignancies. However, the role of FNA in the assessment of new lymphoproliferative disorders continues to be a subject of debate. The objective of the current study was to evaluate the role of molecular cytogenetic studies in FNA diagnoses of lymphoproliferative disorders. METHODS A retrospective, computer-based search for lymph node FNAs from 2006 to 2007 was performed. Cases with either fluorescence in situ hybridization (FISH) and/or polymerase chain reaction (PCR) studies were subjected to further analysis. RESULTS In total, 243 lymph node FNAs were performed during the period, including 104 that were positive/suspicious for metastatic malignancies, 16 that were positive/suspicious for lymphomas, 15 that demonstrated atypical lymphoid proliferation, 73 that were reactive, 14 that were deemed granulomas, and 21 that were determined to be nondiagnostic. Molecular analysis included combined FISH/PCR in 4 cases, FISH only in 7 cases, and PCR only in 4 cases. By using multiplex PCR, 6 cases with atypical/negative flow cytometry results were diagnosed as 4 B-cell lymphomas, 1 T-cell lymphoma, and 1 reactive lymph node; and 4 cases that had atypical T cells determined by flow cytometry were diagnosed as reactive. One CD10-negative follicular lymphoma and 2 cases with suspicious flow cytometry results were positive for t(14;18)(q32;q21) by FISH. Forty-five cases had follow-up histology with 3 false-negative findings and no false-positive results. CONCLUSIONS In this study, multiplex PCR studies for immunoglobulin heavy-chain or T-cell receptor gene rearrangements were useful for demonstrating clonality, and FISH studies were able to detect translocations or gene rearrangements that allowed for the subclassification of B-cell non-Hodgkin lymphomas.

Abstract
Polymerase chain reaction (PCR) assays for the immunoglobulin and T-cell receptor genes were utilized to determine phenotype and clonality from lymph node cytologic smears and peripheral blood lymphocytes from 10 dogs with lymphoma, before chemotherapy and during remission. Results were compared with those from 13 dogs with a cytologic diagnosis of lymph node hyperplasia. Clonality was identified in 7 of the lymphomas on the basis of either lymph node cytology or peripheral blood lymphocytes before treatment. No lymph node hyperplasia samples were clonal. In 6 of the dogs with lymphoma, clonality was demonstrated during clinical remission. Detection of PCR clonality during clinical remission is an effective means of identifying minimal residual disease in canine lymphoma and thus additional work is warranted to determine if molecular remission is prognostic or predictive for outcome in well-controlled and well-defined lymphoma subtypes.

Abstract
The effectiveness of fine-needle aspiration biopsy (FNAB) for rendering a specific diagnosis can be improved by applying several ancillary modalities. This review details several applications of molecular techniques using FNAB specimens with an emphasis on those used for patient care. A detailed search of the literature was conducted to collect all reports that used FNAB for different types of molecular tests. Several types of molecular tests, including in-situ hybridization, polymerase chain reaction, Southern blotting, and gene microarrays using FNAB specimens have been reported. These tests have been used with different organ systems and different objectives, including the detection of cancer cells, diagnosis, distinction of benign and malignant disease, prediction of response to chemotherapy, risk assessment, and selection of patients for targeted therapy. Except for a few tests such as assessment of HER2/neu for gene amplification in breast cancer, detection of clonality in hematopoietic neoplasms, and specific chromosomal translocations in the former and in the diagnosis of soft tissue sarcoma, most of the molecular tests using FNAB specimens are currently investigational. The reported literature indicates the excellent potential of using material procured from FNAB for almost any type of molecular test. Whereas few of these tests alone are used for patient care, some of them have the potential for clinical use in the near future.

Abstract
BACKGROUND Fine-needle aspiration cytology (FNAC) is used as a screening test to evaluate lymphadenopathy. The combined use of genetic analysis and flow cytometry for immunophenotyping has increased the accuracy of diagnosis and correct categorisation of lymphomas on cytological preparations. AIM To show the utility of immunocytochemistry and polymerase chain reaction (PCR) in the evaluation of cytological preparations of lymph nodes. METHODS Fine needle aspirates were obtained from 33 patients (initial presentation, n = 27; recurrence, n = 6). Routine examination was undertaken using immunocytochemistry and DNA PCR to detect clonality and specific translocations. The cytodiagnosis and subclassification of lymphoma was correlated with histological diagnosis in the available follow-up biopsies. RESULTS 14 patients had a cytological diagnosis of non-Hodgkin's lymphoma (NHL), 4 had suspected NHL, 2 had atypical lymphoid proliferation and 13 had reactive hyperplasia. A World Health Organization (WHO) subtype was suggested in 8 patients. Incorporating the results of immunoglobulin heavy chain (IgH) and T-cell receptor (TCR) gene rearrangements enabled diagnosis of lymphoma in 17 patients, including 5 of the 6 patients suspected to have NHL or an atypical lymphoid proliferation. Identification of the translocations t (14;18) and t (2;5) helped WHO categorisation in 3 of the patients. The cytological findings were confirmed in 12 out of the 13 patients for whom histological follow-up was available. Seven of the 18 lymphoma patients were managed without a subsequent biopsy. We made one false-positive diagnosis of B-cell NHL on cytology. CONCLUSION The use of immunocytochemistry and PCR is valuable in the definitive diagnosis and subtyping of malignant lymphomas on cytological preparations. The use of these techniques may avoid lymph node biopsies in some cases and allow definitive treatment based on aspirate findings alone.

Abstract
To determine the accuracy of fine-needle aspiration (FNA) in the diagnostic assessment of lymphadenopathies, a retrospective study was conducted on 627 cases of FNA of the lymph nodes performed at Department of Pathology, UNIFESP (Federal University of São Paulo), between 1997 and 2001. Cytology results were compared to the results of biopsies if available. The cytological diagnosis was unsatisfactory in 14.7% of cases, positive in 46%, and negative in 39.3%. Among the positive cases, 79.4% were classified as metastases, 14.2% as lymphoma, and 6.4% as indeterminate. Anatomopathological exams for the determination of cytohistological correlation were available in 218 of the 627 cases. There were three (1.88%) false-negative and two (1.25%) false-positive cases. Accuracy tests revealed 97.41% sensitivity, 95.45% specificity, and 96.88% efficacy, with cytohistological agreement being almost perfect (kappa = 0.92). The high accuracy of this study based only on cytomorphological criteria associated to the variety of malignant neoplasias diagnosed by the procedure demonstrates its relevance on patient care, especially in areas of limited financial resources.

Abstract
PURPOSE To analyze the clinical, morphologic, immunophenotypic, and molecular genetic differences between idiopathic inflammatory pseudotumor and lymphoid tumors of the orbit. METHODS 209 patients with IOIP and 110 patients with lymphoid tumors seen between January 1, 1978 and December 31, 1999 in Zhongshan Ophthalmic Center, Sun Yat-sen University were evaluated retrospectively. RESULTS More patients with lymphoid tumors had palpable mass than patients with idiopathic orbital inflammatory pseudotumor (IOIP) (P < 0.0001), with the percentage of 90% and 65%, respectively, whereas more patients with IOIP had swollen eyelid, eyelid or conjunctival congestion, pain, retinal folds or hamorrhage, and optic nerve atrophy than patients with lymphoid tumors, with the percentage of 55% and 40% (P = 0.014), 42% and 24% (P = 0.001), 24% and 1% (P < 0.0001), 14% and 4% (P = 0.004), 7% and 2% (P = 0.043), respectively. Ultrasound and computed tomography/magnetic resonance image (CT/MRI) scan usually could not differentiate IOIP from lymphoma. Nearly one third of patients with IOIP could not be easily differentiated pathologically from lymphoid tumor. Immunophenotypic, and molecular genetic analyses can differentiate IOIP from lymphoid tumor based on polyclonal or monoclonal proliferation of lymphocytes with the IOIP being polyclonal and lymphoma monoclonal. CONCLUSIONS Idiopathic orbital inflammatory pseudotumor and lymphoid tumor showed distinguishing clinical, morphologic, immunophenotypic, and molecular genetic characteristics.

Abstract
The purpose of this study was to investigate whether B-cell clonality could be demonstrated in fine-needle aspiration (FNA)-type preparations by using automated and manual in situ hybridization (ISH) systems. FNA-like preparations were made from 10 cases of B-cell lymphoma and 5 cases of reactive lymphoid hyperplasia. Kappa/lambda expression was determined using an automated mRNA ISH assay or a manual ISH system. Other variables tested included type and length of fixation, protease digestion, and time in chromogen. Clonality data were corroborated by either flow cytometry or tissue-based analysis. Optimal conditions required formalin fixation, strong protease digestion, and prolonged hybridization and chromogen times; under these conditions, monoclonality was demonstrated by in situ in 8 of 10 cases. Each of the five cases of reactive lymphoid hyperplasia showed polyclonal light chain expression by automated mRNA ISH. In situ kappa/lambda mRNA analysis of FNA-type specimens allows direct determination of monoclonality in cytologic preparations.

Abstract
This study addresses the utility of fine-needle aspiration (FNA) in assessing lymphadenopathy in patients with and without a previous history of malignancy. We reviewed the FNAs of superficial and deeply seated lymph nodes performed at our institution over a period of 18 yr (1983-2001). Where applicable, we also reviewed and report here the results of subsequent surgical excisional biopsies. We analyzed data from 439 patients, who ranged in age from 1 to 90 yr. The neck and retroperitoneum were the most frequently sampled sites (47% and 25%, respectively). Among the 439 FNAs, adequate material was obtained in 421 cases (96%); the remaining 18 were unsatisfactory (4.1%). Malignant diagnoses were rendered in 330 cases (75% of 439), four were suspicious for lymphoma (0.9%), and 87 were read as reactive lymph nodes or granulomas (20%). The most common malignant cytologic diagnoses from these lymph node FNAs were adenocarcinoma, squamous cell carcinoma, and lymphoma. We compared results between two major groups: patients with a history of malignancy and those without. FNA showed malignancy in 87% of patients with a history of cancer and 41% without such a history. Thirty-three or 10% of patients with a history of malignancy were given a benign diagnosis and follow-up surgical excisional biopsies were performed in nine of these cases. Four of the nine showed low-grade lymphoma. Of the 18 non-diagnostic FNAs, nine came from patients with a history of malignancy and in six of these nine who had a follow-up surgical excisional biopsy the lymph nodes were positive for malignancy. Of the other nine, who had no history of malignancy, only two had follow-up biopsies and both of these were negative. Patients with a history of malignancy are more than twice as likely to show malignancy on lymph node FNA compared to those without such a history (87% vs. 41%). Knowing whether a patient has a history of malignancy provides the appropriate level of suspicion for ordering ancillary investigations or even recommending excisional biopsy for further evaluation.

Abstract
AIMS Fine needle aspiration (FNA) cytology is an accepted means of diagnosing and typing common forms of lymphoma, particularly small lymphocytic lymphoma, follicular lymphoma, and large B cell lymphoma. However, its usefulness for diagnosing less common forms of lymphoma is not clearly established and this study was designed to examine this. METHODS The study reviewed the FNAs of suspected lymphomas collected over a period of approximately five years. RESULTS FNA samples were available for 138 definite lymphomas; most were common forms of B cell lymphoma. However, there was also one Burkitt lymphoma (BL), two Burkitt-like large B cell lymphomas, 15 classic Hodgkin lymphomas (HLs), two nodular lymphocyte predominant Hodgkin lymphomas, four mantle cell lymphomas, two mediastinal (thymic) large B cell lymphomas (MLBCLs), 11 peripheral T cell lymphomas (PTCLs), and five T cell rich large B cell lymphomas (TCRLBCLs). CONCLUSIONS FNA diagnosis of BL was possible with immunoflow cytometry (IFC), cell block immunohistochemistry (IHC), and cell block fluorescent in situ hybridisation for c-myc alteration. It was difficult to make a definite diagnosis of HL and MLBCL on FNA alone. Both tend to be sclerotic tumours and FNA tends to yield scanty neoplastic cells. The FNA diagnosis of PTCL depended on cell block IHC; IFC was not usually useful. TCRLBCL did not show light chain restriction on IFC of FNA samples, probably because of frequent reactive B cells in the tumour. Thus, HL, MLBCL, and TCRLBCL are often difficult to diagnose accurately on FNA cytology, even when using IFC and cell block IHC.

Abstract
BACKGROUND Different polymerase chain reaction (PCR) assays have proved to be useful tools for the detection of clonal immunoglobulin heavy chain (IgH) gene rearrangements in frozen or paraffin-embedded tissues. However, the usefulness of a single primer pair PCR assay on fine-needle biopsy aspirates has not been proven yet. METHODS The authors conducted a wide prospective study of 148 lymph nodes and extranodal lymphoid infiltrates obtained by fine-needle aspiration biopsy (FNAB). The power of a single primer pair PCR amplification of the hypervariable CDRIII region IgH genes was evaluated using a pair of consensus primers. The PCR cytologic results were compared with the final clinicopathologic diagnosis of each case assessed by combining cytologic and/or immunophenotypic data and histologic features or clinical follow-up. RESULTS Among the 139 cases with an evaluable PCR result, 35 of 40 (87%) B-cell non-Hodgkin lymphomas were detected as a monoclonal band. Monoclonal IgH bands also were detected in two of the five (40%) T-cell lymphomas, two of the seven (29%) Hodgkin lymphomas, and 5 of the 87 (6%) reactive lymphoid disorders. These results are similar to those obtained by other authors using seminested PCR or combining different PCR tests in each sample obtained by FNAB or excisional biopsy. CONCLUSIONS The results of the current study demonstrate the convenience of a single primer pair PCR amplification over seminested methods in terms of lower cost and workload. The existence of PCR false-negative and false-positive results for lymphoma makes it necessary to combine the information obtained by PCR with cytologic and/or immunophenotypic data to optimize the number of lymphoid malignancies correctly diagnosed by FNAB.

Abstract
We discuss nine cases identified at our institution with prominent Reed-Sternberg-like cells in fine-needle aspiration of lymph nodes in patients without Hodgkin's disease. Cytomorphology was studied using Diff-Quik and Papanicolaou-stained smears and flow cytometric analysis was performed in all cases. Clinical and/or histopathologic follow-up was reviewed. Of the nine cases, all were diagnosed as "atypical lymphoid proliferation" despite a negative flow cytometric analysis. Clinicopathologic follow-up revealed that three cases evolved into malignant non-Hodgkin's lymphoma and one case into a posttransplant lymphoproliferative disorder. The remaining five cases were benign in the follow-up period also, of which one case was later diagnosed as an inflammatory pseudotumor. In two cases of reactive hyperplasia and in the inflammatory pseudotumor case, an in situ hybridization stain for Epstein Barr virus (EBV) was positive. The significance and differential diagnosis of Reed-Sternberg-like cells in lymph nodes in the absence of Hodgkin's disease is discussed.

Abstract
BACKGROUND Adult T-cell leukemia/lymphoma (ATLL) is a postthymic lymphoproliferative neoplasm of T cells caused by human T-cell lymphotropic virus (HTLV-1). Most cases are found in Japan, the Caribbean basin, and West Africa. DESIGN To identify diagnostic parameters for cytology in this neoplasm, the authors undertook a retrospective review of all ATLL samples from 1990 to 2000. RESULTS One hundred fourteen samples from 34 patients with the diagnosis of ATLL were reviewed: 80 cerebrospinal fluids, 7 pleural effusions, 4 bronchoalveolar lavages, 2 peritoneal effusions as well as fine-needle aspirations of 15 lymph nodes, 4 subcutaneous lesions, and 2 breast nodules. Twenty-one patients were women and 13 were men, with an age range of 30 to 71 years. Morphologically, all specimens were characterized by the presence of a polymorphous population of lymphocytes ranging from small bland-appearing lymphocytes to large atypical ones with bizarre, multilobulated nuclei (flower-like or clover leaf cells) with coarse chromatin and prominent nucleoli. The cytoplasm was deeply basophilic with occasional vacuoles. Immunocytochemistry was performed on 17 specimens from 14 patients. In all cases tested, tumor cells were immunoreactive for CD3, CD4, CD5, and CD25 and were nonimmunoreactive for CD7 and CD8. Flow cytometry was performed on 12 specimens from 9 patients. The tumor cells in all cases tested were positive for CD2, CD3, CD4, CD5, and CD25 and were negative for CD7. CONCLUSIONS Despite the polymorphous nature of ATLL, diagnosis can be established by close attention to nuclear cytologic features in conjunction with ancillary studies such as immunocytochemistry and/or flow cytometry.

Abstract
OBJECTIVES Fine-needle aspiration biopsy (FNAB) is a technique in which a fine needle is introduced into a mass, cellular material is aspirated, and a cytological diagnosis is rendered. It separates reactive and inflammatory processes that do not require surgical intervention from neoplasia and benign from malignant tumors. FNAB lends itself to the diagnosis of palpable head and neck masses, in particular, those that persist following antibiotic treatment. STUDY DESIGN/METHODS This clinical state-of-the-art review article is intended to provide an overview of the clinical use of FNAB in the management of head and neck masses. Relevant case histories are used to illustrate this point. RESULTS Fine-needle aspiration biopsy has a high overall diagnostic accuracy of 95% for all head and neck masses, 95% for benign lesions, and 87% for malignant ones. CONCLUSIONS There are virtually no contraindications, and complications are minimal. Advantages of FNAB are that it is safe and simple, it can be performed as an outpatient procedure, and it is well tolerated by patients. In the present managed care environment, it also proves cost-effective. The diagnosis is readily known to the clinician, and appropriate treatment modalities can be discussed with the patient. It is recommended as a first line of investigation in palpable head and neck masses.

Abstract
Large cell lymphomas often challenge the diagnostic flow cytometrist. The purposes of this study were to improve our protocols for diagnosing large cell lymphomas and to correlate flow cytometric (FC) data with demographic and histologic features. We identified 63 cases of large B-cell lymphoma between January 1, 1995, and July 30, 1999, and reviewed the diagnostic slides and FC light scatter and staining patterns. The 51 lymphomas with adequate material for systemic review fell into 2 light scatter patterns: "clear cut," with large abnormal cells (high forward scatter relative to normal lymphocytes), 17 cases (33%); and "complex," 34 cases (67%). Clear-cut cases were more mitotically active (average of 42 vs 25 per 10 high-power fields), with higher cellularity. Apoptosis, geographic necrosis, and sclerosis were present histologically in many cases, regardless of FC findings. We conclude that morphologic features of large cell lymphomas do not predict which cases will be difficult to diagnose by FC. Gating strategies can be critical to improve the diagnostic yield.

Abstract
OBJECTIVE To study the clinical efficacy of flow cytometry in patients suspected of having a lymphoma with head and neck pathology. STUDY DESIGN Retrospective review of 49 patients with lymphoid aspirates having concurrent flow cytometry studies. SETTING Private practice office-based study. CONCLUSION Fine-needle aspiration with concurrent flow cytometry is a useful, convenient adjunct to the diagnosis of head and neck non-Hodgkins lymphomas. SIGNIFICANCE Flow cytometry is a significant improvement over fine-needle aspiration derived cytologic diagnosis alone. Tissue open biopsy may be avoided altogether in some patients with non-Hodgkins lymphoma.

Abstract
We retrospectively reviewed our experience with the fine-needle aspiration biopsy (FNAB) diagnosis of primary and recurrent lymphoma to assess the ability of cytomorphology with and without ancillary flow cytometry (FCM) analysis to diagnose and subclassify these tumors according to the Revised European-American Lymphoma/World Health Organization classifications. We reviewed 139 consecutive FNABS of 84 primary and 55 recurrent lymphomas. FCM was successful in 105 (75%) cases. The overall results, including cases without FCM, included 93/139 (67%) true positive, 7 (5%) false negative, and 39 indeterminate (27 [19%] suspicious and 12 [9%] atypical) diagnoses of lymphoma. In cases with FCM, there were 80/105 (77%) true positive, no false negative, and 25 indeterminate diagnoses (15 [14%] suspicious and 10 [9%] atypical). The overall results of the 84 primary lymphomas were 55 (67%) true positive, 5 (5%) false negative, and 24 indeterminate (14[16%] suspicious and 10 [12%] atypical) diagnoses for lymphoma. Of the 68 primary lymphomas analyzed with FCM, 50 [74%] were true positives, and 28 were indeterminate (11 [16%] suspicious and 7 [10%] atypical). There were no false negatives. Diagnostic accuracy varied among lymphoma subtypes. Subclassification of the positive cases were initially conclusive in only 55/93 cases (59%). However, a retrospective review of the morphologic together with FCM data in 15 of the 23 unclassified cases improved the overall subclassification of positive cases to 77%. Subclassification was best in small lymphocytic lymphoma/chronic lymphocytic leukemia, lymphoplasmacytic lymphoma, Burkitt's lymphoma, mantle cell lymphoma, and plasmacytoma (all 100%). Subclassification was poor in marginal-zone lymphoma (33%), and initially as well in diffuse large B-cell lymphoma (62%), but it improved on review (95%), as did subclassification of follicular lymphoma (77 to 100% on review). Hodgkin's disease was recognized as malignant in only 44% of the cases (7/16) and was classified as such based on morphology alone. This review of our early efforts to diagnose and subclassify lymphoma with FNAB and FCM indicates that although a diagnosis and proper subclassification of lymphoma can be made with certainty in the majority of cases, recurrent or primary, it requires close coordination of cytomorphology and immunophenotyping data, which often comes with close cooperation of cytopathologists and hematopathologists. A mere cytological diagnosis of positive for lymphoma is no longer acceptable if FNAB is to become an independent diagnostic tool for lymphoma.

Abstract
INTRODUCTION Peripheral T-cell lymphoma (PTCL) accounts for 10-20% of all non-Hodgkin lymphomas in the United States. In this study, the authors reviewed the cytologic and immunophenotypic findings of 33 fine-needle aspirations (FNAs) of PTCL. METHODS Thirty-three FNAs from 26 patients (12 females and 14 males) with PTCL were identified during 1991-1999. The patients' age ranged from 19 to 96 years. Immunophenotyping was performed in 24 cases by using either flow cytometry (FC; 21 cases) or immunocytochemistry (IC; 3 cases). Follow-up included review of prior or current histology and clinical records. RESULTS Nine cases were associated with mycosis fungoides, three cases were classified as T-cell chronic lymphocytic leukemia, and two were angioimmunoblastic adenopathy (AILD)-like T-cell lymphoma. The remaining 19 were classified as PTCL, not otherwise specified. The latter consisted of eight mixed cell variant, eight large cell variant, and three anaplastic variant. One of the mixed cell variant and one of the large cell variants contained numerous epithelioid histiocytes (Lennert lymphoma). Thirty (91%) cases had a definitive diagnosis of malignant lymphoma. Twenty-two cases (2 IC and 20 FC) showed a predominant population of T lymphocytes without a monoclonal B-cell population. In addition, FC revealed an aberrant expression of T-cell markers in 13 cases. Two cases were interpreted as "atypical lymphoid population"; one case was an AILD-like T-cell lymphoma, and the other case was PTCL, large cell type. One case initially was interpreted as granulomatous lymphadenitis; subsequent biopsy revealed PTCL, Lennert type. CONCLUSIONS Peripheral T-cell lymphoma is a heterogeneous group of lesions with diverse cytomorphology. Cytologic analysis and immunophenotyping is an accurate method of diagnosing peripheral T-cell lymphoma.

Abstract
BACKGROUND Limited information is available regarding the use of EUS-guided fine-needle aspiration (EUS-FNA) in the diagnosis of lymphoproliferative disorders. The aim of this study was to evaluate the yield of this technique in the primary diagnosis of lymphoma. METHODS The records were reviewed of 38 consecutive patients with GI lesions and/or enlarged lymph nodes identified on imaging studies that raised a suspicion of lymphoma who underwent EUS-FNA of lymph nodes or the gut wall. Final diagnosis was based on clinical follow-up, imaging studies, or surgical findings. RESULTS Twenty-three patients with lymphoma and 15 patients with benign disease or reactive lymphadenopathy were identified. The overall sensitivity, specificity, and accuracy of EUS-FNA cytology with flow cytometry/immunocytochemistry (FC/IC) for the diagnosis of lymphoma were, respectively, 74%, 93%, and 81%. When comparing patients who had EUS-FNA with FC/IC versus those who had EUS-FNA without FC/IC, sensitivity was 86% versus 44% (p = 0.04), specificity was 100% versus 90% (not significant), and accuracy was 89% versus 68% (not significant). CONCLUSION EUS-FNA can provide cytology specimens diagnostic for lymphoma. Selective use of FC/IC in patients with suspected lymphoma improves the yield of EUS-FNA and may guide diagnostic evaluation and treatment decisions.

Abstract
Fine-needle aspiration (FNA) is an effective tool in evaluating the cause of lymphadenopathy. While the morphologic diagnosis of a reactive lymphoid proliferation is common in younger patients, this diagnosis should be made carefully in older patients (those over the age of 50 yr) in light of the facts that such purely reactive conditions occur much less frequently in this population, and that follow-up of these patients reveals a malignancy (usually lymphoma) in a significant number of cases. In this series, we identified 40 patients with a morphologic diagnosis of reactive lymphoid proliferation on FNA and obtained their follow-up information. Of 19 patients under the age of 50 yr, 5 underwent subsequent biopsies and only one revealed a definitive malignancy (5%). In contrast, 7 of 21 patients over the age of 50 yr underwent a subsequent biopsy, and 6 were found to have a malignancy (5 malignant lymphomas, 1 metastatic melanoma). The higher rate of positive follow-up (29%) in this age group supports previous suggestions that morphologically reactive (mixed) lymphoid proliferations be viewed with increased suspicion in the elderly patient, and that additional studies, such as flow cytometry, be performed when material is available.

Abstract
Fine needle aspiration cytology (FNAC) was performed under ultrasound and CT guidance in 120 cases. These included abdominal masses (85 cases) and thoracic masses (35 cases) biopsied over a two and a half year period (March 1996 to September 1998). The aim of this study was to assess the contribution of clinico-imaging evaluation and image-guided FNAC to the management of patients with deep-seated mass lesions. Aspirations in the abdomen were performed from various anatomic sites such as liver (56 cases), lymph nodes (18 cases), gastrointestinal tract (three cases), pancreas (six cases), and kidney (two cases). In the thorax, biopsy was performed in the lung (19 cases) and mediastinum (13 cases). In 112 cases (93.4%) FNAC was diagnostic. Of the lesions that were successfully aspirated, 85% were < or = 5 cm in size. No major complication was encountered. All the successful aspirates could be defined as malignant or non-malignant, but tissue differentiation was possible in 63.7% of malignant lesions and 53.8% of benign lesions. Combined clinical and imaging evaluation for malignancy showed 80% sensitivity and 59% specificity. Although clinicoradiological parameters themselves have certain limitations in diagnosing benign versus malignant lesions, in conjunction with guided FNA they are very accurate and safe in diagnosing deep-seated mass lesions in the thorax and in the abdomen. However, the role of FNA in tissue differentiation of solid lesions such as lymphoma requires further study.
