Krishnan V, Victor AR, Bose S, Bakkar R. Lymphoid cell rich fine-needle aspirations of the salivary gland: What is the risk of malignancy? Cytojournal 2023; 20:11. [PMID: 37292122 PMCID: PMC10246398 DOI: 10.25259/cytojournal_4_2022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Accepted: 08/21/2022] [Indexed: 06/10/2023] Open
Abstract
Objectives Lymphoid cell rich fine-needle aspirations (FNAs) of the salivary glands pose a diagnostic dilemma, with a wide range of differential diagnoses that include several benign and malignant entities. There is limited literature regarding the entities that are commonly encountered in this situation. Our goal was to characterize the surgical outcome in these cases and to evaluate the risk of malignancy. Material and Methods This is a retrospective study at a tertiary care institution. Our database was queried over a 10-year period. FNAs yielding a prominent population of well-visualized lymphoid cells were included in the study. Only cases with surgical follow-up were evaluated. FNAs with epithelial cells, diagnostic features of any entity (such as granulomas or chondromyxoid stroma), history of metastatic malignancy, or scant cellularity were excluded from the study. Lymphoid cells were classified as atypical according to morphologic findings (monomorphism, irregular nuclear contours, and abnormal chromatin patterns). Statistical analysis was performed. Results Of the 224 lymphoid cell rich FNAs identified, 29 (28%) had surgical follow-up in our data records. Twenty-two were from the parotid and seven from the submandibular gland. Ten cases (35%) were non-neoplastic (benign lymphoepithelial cyst [n = 4], reactive lymph node [n = 5] and chronic sialadenitis [n = 1]). Benign epithelial neoplasms including pleomorphic adenoma (n = 2) and Warthin's tumor (n = 1) were identified in 10% of the cases. One case with non-atypical lymphocytes proved to be a mucoepidermoid carcinoma (n = 1). Lymphomas were detected in 52% (n = 15). Of note, none of these patients had a history of lymphoid malignancy. 8/15 were low-grade and 7/15 were high-grade lymphoma. Most of these cases (11/15) had atypical lymphocytes on FNA. Ancillary studies were available in a few cases and supportive of the diagnosis of lymphoma, including cell block and immunohistochemistry (n = 7, 47%), flow cytometry (n = 3, 27%), and clonality polymerase chain reaction (PCR) (n = 1; 7%). Most of these were performed in cases with atypical lymphocytes. In cases with non-atypical lymphocytes, five cases were malignant on surgical excision (5/17). Morphology on FNA had a specificity of 92% for malignancy and sensitivity of 69%. The positive predictive value on FNA of atypical lymphocytes for malignancy was 92%. Conclusion Lymphoid cell rich FNAs carry a 52% incidence rate lymphoma in our small study population. Specificity of FNA for malignancy is high (92%) and lymphocyte atypia is a strong predictor of malignancy. Ancillary studies may be of added value in FNAs with non-atypical lymphoid cells. FNA has a valuable role in triaging lymphoid lesions of the salivary glands.

Fine-needle aspiration cytology for the diagnosis of plasma cell neoplasms in the head and neck region: A systematic analysis of the literature. Diagn Cytopathol 2023; 51:198-210. [PMID: 36576947 DOI: 10.1002/dc.25095] [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: 09/06/2022] [Revised: 12/04/2022] [Accepted: 12/16/2022] [Indexed: 12/29/2022]
Abstract
BACKGROUND Cytopathologic analysis is feasible and provides detailed morphological characterisation of head and neck lesions. AIMS To integrate the available data published on fine-needle aspiration cytology (FNAC) used for the diagnosis of plasma cell neoplasms (PCN) of the head and neck region. MATERIALS AND METHODS Searches on PubMed, Web of Science, Embase, and Scopus were performed to compile data from case reports/case series published in English. The Joanna Briggs Institute tool was used for the critical appraisal of studies. RESULTS A total of 82 studies comprising 102 patients were included in this review. There was a predilection for men (68.6%) (male/female ratio: 2.1:1). Individuals in their 50s (29.4%), 60s (22.5%), and 70s (22.5%) were more often affected. The thyroid gland (26.2%) was the main anatomical location, followed by scalp (15.5%), neck/cervical region (15.5%), jaws (13.6%), and major salivary glands (13.6%). For FNAC analysis, a smear was employed in 41 (40.6%) cases and a cell block was used in four (3.9%). In 56 (55.4%) reports, no cytological methods were available. Morphologically, 34 (56.7%) cases had a diagnosis of PCN with agreement between cytopathology and histopathology. The rate of wrong diagnoses when using cytology was 27.5%. Immunophenotyping was performed in 49 (48%) of the cases. The 69-month disease-free survival rate was 60.2%, while the 27-month overall survival rate was 64.1%. CONCLUSION This study reinforces that FNAC can be an ancillary tool in the first step towards the diagnosis of PCN of the head and neck region, especially when applying a cell block for cytological analysis.

A multi-institutional study of salivary gland cytopathology: Application of the Milan System for Reporting Salivary Gland Cytopathology in Japan. Cancer Cytopathol 2021; 130:30-40. [PMID: 34478237 PMCID: PMC9290724 DOI: 10.1002/cncy.22505] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2021] [Revised: 06/14/2021] [Accepted: 06/17/2021] [Indexed: 11/15/2022]
Abstract
Background The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) is a risk‐stratification reporting system that was introduced in 2018. The objective of this multi‐institutional study was to evaluate the utility of the MSRSGC in Japan. Methods In total, 1608 fine‐needle aspiration samples with matching histologic diagnoses were retrieved from 12 large institutions in Japan. The diagnostic categories of the MSRSGC were assigned prospectively or retrospectively, and the results were compared with the histologic diagnoses. Results The cases were classified as follows: nondiagnostic, 18.1%; non‐neoplastic, 4.1%; atypia of undetermined significance, 11.5%; neoplasm‐benign, 43.7%; salivary gland neoplasm of uncertain malignant potential, 9.6%; suspicious for malignancy, 3.6%; and malignant, 9.4%. The risk of neoplasm and the risk of malignancy in each MSRSGC category were as follows: nondiagnostic, 72.9% and 13.4%, respectively; non‐neoplastic, 15.2% and 9.1%, respectively; atypia of undetermined significance, 77.9% and 24.9%, respectively; neoplasm‐benign, 99% and 1.8%, respectively; salivary gland neoplasm of uncertain malignant potential, 94.8% and 37%, respectively; suspicious for malignancy, 100% and 89.7%, respectively; and malignant, 100% and 99.3%, respectively. The accuracy of the MSRSGC for diagnosing neoplasms was 97.8%, and its accuracy for diagnosing malignancy was 97.3%. Institutions that used Romanowsky‐stained preparations had lower nondiagnostic rates and lower risks of neoplasm and malignancy in the non‐neoplastic category. Conclusions The MSRSGC is useful for risk stratification and quality control. Widespread use of the MSRSGC would improve the accuracy of salivary gland cytology and lead to better patient care in Japan. This is the first multi‐institutional study of a large‐scale application of the Milan System for Reporting Salivary Gland Cytopathology in Japan. It demonstrates the usefulness of the Milan system in the diagnosis of salivary gland lesions and for the quality control of salivary gland cytology results.

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
PURPOSE To provide evidence-based recommendations for practicing physicians and other healthcare providers on the management of salivary gland malignancy. METHODS ASCO convened an Expert Panel of medical oncology, surgical oncology, radiation oncology, neuroradiology, pathology, and patient advocacy experts to conduct a literature search, which included systematic reviews, meta-analyses, randomized controlled trials, and prospective and retrospective comparative observational studies published from 2000 through 2020. Outcomes of interest included survival, diagnostic accuracy, disease recurrence, and quality of life. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations. RESULTS The literature search identified 293 relevant studies to inform the evidence base for this guideline. Six main clinical questions were addressed, which included subquestions on preoperative evaluations, surgical diagnostic and therapeutic procedures, appropriate radiotherapy techniques, the role of systemic therapy, and follow-up evaluations. RECOMMENDATIONS When possible, evidence-based recommendations were developed to address the diagnosis and appropriate preoperative evaluations for patients with a salivary gland malignancy, therapeutic procedures, and appropriate treatment options in various salivary gland histologies.Additional information is available at www.asco.org/head-neck-cancer-guidelines.

Abstract
OBJECTIVE The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) is a recently published evidence-based categorization system for salivary gland fine-needle aspiration (FNA). We applied MSRSGC to Japanese cases and evaluated its utility. STUDY DESIGN A total of 480 FNA cases were reviewed. We recategorized each case into one of the MSRSGC categories. The risk of neoplasm (RON) and the risk of malignancy (ROM) for each diagnostic category in MSRSGC, and the sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) for malignancy and for neoplasms were calculated for cases with histological follow-up. In addition, the overall ROM (O-ROM) was calculated for all FNA cases. RESULTS RON, ROM, and O-ROM rates were as follows - non-diagnostic: 51.3, 5.1, and 1.0%; non-neoplastic: 0, 0, and 0%; atypia of undetermined significance: 83.9, 12.9, and 7.3%; neoplasm, benign: 100, 0, and 0%; salivary gland neoplasm of uncertain malignant potential: 100, 32.1, and 23.7%; suspicious for malignancy: 100, 85.7, and 60%; and malignant: 100, 100, 81.8%. The sensitivity, specificity, and accuracy with (without) indeterminate cases for malignancy were 65 (100), 99 (99), 92% (99%) and PPV and NPV were 96 and 100%, respectively, and those for neoplasms were 84 (100), 100 (100), 85% (100%), and PPV and NPV were 100 and 100%, respectively. CONCLUSIONS The MSRSGC is useful for stratification of ROM and for promoting the performance of salivary gland FNA. The MSRSGC could be easily introduced in Japan and may improve the Japanese salivary gland FNA status.

Abstract
BACKGROUND Atypia of undetermined significance (AUS) is a category of the Milan System for Reporting Salivary Gland Cytopathology that refers to salivary gland fine-needle aspiration (FNA) specimens that cannot be definitively diagnosed as neoplastic or nonneoplastic. METHODS The AUS FNA samples were selected from a large academic institution from 2008 through 2018. The AUS cases were divided into 6 subgroups. The risk of malignancy (ROM), risk of neoplasm (RON), and clinical outcomes for each subgroup were evaluated. RESULTS A total of 123 cases were found (76 males and 47 females with a mean age of 62 years [range, 6-94 years]). The parotid gland was the most common FNA site (103 cases), followed by the submandibular gland (9 cases). The overall RON and ROM were 63% and 47%, respectively. Among the subgroups, salivary gland lymph nodes or lymphoid lesions was the most common diagnosis (42%), whereas mucinous cystic lesions with no or a scant epithelial component was the least common (2%). The specimens with preparation artifacts category had the highest RON and ROM (100% for both), whereas the reactive and reparative atypia indefinite for a neoplasm category had the lowest RON and ROM (7% for both). The salivary gland lymph nodes or lymphoid lesions indefinite for a lymphoproliferative disorder category had the second highest RON and ROM at 77% and 74%, respectively. CONCLUSIONS The overall RON and ROM for the AUS category were 63% and 47%, respectively. The RON and ROM varied among the different AUS subgroups, being highest in the specimens with preparation artifacts category and lowest in the reactive and reparative atypia category, thereby demonstrating the importance of subgrouping in the AUS specimens.

Abstract
Benign lymphoepithelial lesion (BLEL) is characterized by extensive lymphocytic infiltration of the major salivary glands and may be associated with Sjogren's syndrome or HIV infection. The involvement of the palatal minor salivary glands is extremely rare. We report an isolated case of BLEL affecting the palatal minor salivary glands, presenting as a palatal swelling in a 37-year-old female patient. Serological tests ruled out potential comorbid conditions. Cone-beam computed tomography showed a palatal soft-tissue mass with thinning of the adjacent cortical plates. A histopathological examination revealed salivary gland tissue with significant acinar destruction, dense lymphocytic infiltration and focal myoepithelial islands. Therefore, BLEL may be considered as a rare differential diagnostic possibility of a palatal soft-tissue mass lesion.

Abstract
The benign lymphoepithelial lesion is a rare and diagnostically challenging entity. Classically, these lesions present as early manifestation of HIV infection and are rarely seen in those on highly active antiretroviral therapy. We describe 2 rare cases of HIV-associated lympho-epithelial lesions of parotid gland in a 37-year-old female and a 47-year-old male receiving antiretroviral therapy. The lesions were characterized with respect to clinical features, as well as histopathology and radiology findings. Fine-needle aspiration cytology revealed benign squamous epithelium and lymphocytes. Sonographic evaluation of the parotid gland demonstrated intraparotid solid hypoechoic nodule. Computed tomography showed cystic and solid masses. These lesions were diagnosed as benign lymphoepithelial lesions in both cases. To our knowledge, this is the first report in the published literature describing newly occurring benign lymphoepithelial lesions in patients on antiretroviral therapy.

Abstract
Primary lymphoma of the parotid gland is relatively rare and constitutes about 4-5% of extranodal lymphomas. The majority of them is non-Hodgkin lymphoma (NHL) and is B cell in nature. We report a case of primary diffuse large B-cell lymphoma (DLBCL) of the parotid gland in an elderly male. The case was diagnosed on fine needle aspiration cytology (FNAC) of the right parotid gland as high grade B-cell NHL and confirmed on histopathology as DLBCL. In correlation with the clinicoradiological findings, the case was diagnosed as primary parotid DLBCL. The case highlights the role of FNAC as a timely and useful diagnostic tool.

Abstract
AbstractBackground:Many patients with human immunodeficiency virus present with atypical features. Early indicators of human immunodeficiency virus are scarce and hence most affected patients are diagnosed in the later stages of the disease, which is associated with poor prognosis. Salivary gland disease usually develops before acquired immunodeficiency syndrome, and is sometimes the first manifestation of human immunodeficiency virus infection. Salivary gland lesions include benign lymphoepithelial cysts of the parotid gland, which are seen in 3–6 per cent of patients. Many of the reported lesions are diagnosed on routine examination.Objective:This review aimed to highlight the association between parotid gland benign lymphoepithelial cyst and human immunodeficiency virus infection, in order to aid early diagnosis and management of the disease.Conclusion:Human immunodeficiency virus testing is recommended for patients with benign lymphoepithelial cysts, as this can often be the first indication of human immunodeficiency virus infection. Benign lymphoepithelial cysts are important diagnostic and prognostic indicators in human immunodeficiency virus infection.

Abstract
OBJECTIVE Facial nerve preservation and oncological safety are crucial in surgery of parotid tumors. An unexpected histopathologic diagnosis of a malignant parotid tumor, however, may unfavorably require a second, more radical surgery. The aim of this study was to find out whether the assessment of serological tumor markers in parotid saliva might have some diagnostic significance in the preoperative differentiation between benign and malignant parotid lesions. STUDY DESIGN, SETTING, PATIENTS, AND METHODS: In a prospective pilot study performed at a university medical center in 28 patients with a unilateral parotid tumor, 7 serological tumor markers established in the clinical routine were quantitatively assessed in parotid saliva collected simultaneously on both sides after stimulation. The results were correlated with the histopathological diagnosis. RESULTS Of the 4 investigated tumors that were malignant neoplasms, 3 had a sufficient quantity of saliva available for tumor marker measurements. Carbohydrate antigen 19-9 (CA 19-9) consistently revealed high levels compared with the unaffected side in all malignant tumors, thus allowing malignant tumors to be differentiated from benign lesions. CONCLUSION The results of this pilot study are encouraging, showing that preoperative tumor marker investigation in saliva from parotid glands is feasible and merits further investigation. CA 19-9 might be a valuable new diagnostic tool in the preoperative differentiation between malignant and benign parotid tumors and should be investigated in a larger number of patients.

Abstract
Lymphoid tissue located in the head and neck region include multiple regional lymph node chains as well as mucosa associated lymphoid tissue of the conjunctiva, buccal and nasopharyngeal cavities (Waldeyer's ring), and thyroid and salivary glands. This region is a rich source of antigenic stimuli including infectious agents coming from the outside environment. Many reactive conditions that affect lymphoid tissue in this region may mimic neoplasia. In fact, distinguishing between benign and malignant lymphoid proliferations in the head and neck region is a relatively frequent diagnostic challenge and in many instances, this distinction is not straightforward. It therefore behooves the practicing pathologist to be able to recognize the benign lymphoproliferative disorders that affect this region so as to effectively guide the appropriate clinical management of such patients. Kimura disease, Epstein Barr lymphadenitis, HIV associated salivary gland disease and chronic sialadenitis are benign conditions that not infrequently affect lymphoid tissue in the head and neck region and that share certain overlapping features with malignant lymphoma. In this brief review, we discuss these conditions and highlight clinicopathological features that may help distinguish them from neoplastic lymphoproliferations that may share similar features.

Abstract
BACKGROUND This study evaluates the diagnostic role of preoperative cytology of parotid neoplasms. The method is particularly useful in the evaluation of the parotid diseases in which the same clinical features may be treated variously. Fine-needle aspiration biopsy is a simple and well-tolerated diagnostic tool, which provides accurate information for diagnosis and follow-up of the disease. The accuracy of the method partly depends on the operator skill. MATERIALS AND METHODS From a series of 452 subjects who underwent parotidectomy, preoperative cytological evaluation was available in 310 and compared with histological diagnosis in a retrospective review. RESULTS The agreement between histotype determination using fine-needle aspiration biopsy and final histological diagnosis was 79%, specificity was 100%, sensitivity was 83%, and diagnostic accuracy was 97%. CONCLUSION These findings demonstrated that, given the low complication rate, preoperative cytology is particularly useful in diagnosing parotid disease and in planning the surgical strategy and approach.

Abstract
OBJECTIVES There is a diversity of opinion regarding the role of fine needle aspiration cytology (FNAC) in the pre-operative evaluation of the parotid mass. This study further investigates the role of FNAC from the standpoint of the clinician attempting to resolve one or more clinical issues. METHODS A retrospective study conducted at two UK Hospitals with no overlap of cytopathologists or surgeons. Patients undergoing parotidectomy at each institution were identified from Pathology department databases. The definitive histopathological diagnosis was compared with any pre-operative FNAC diagnosis. Cytology results were classified as suggestive, non-diagnostic, sampling error, or misleading. SETTING The study was conducted in a District General Hospital and a University Teaching Hospital providing secondary care for each community. RESULTS For the University Teaching Hospital the sensitivity in distinguishing malignant from benign disease was 79% (95% CI 61-97%) with a specificity 84% (95% CI 73-95%). However, three of eight patients with a primary parotid salivary gland malignancy were reported as having benign disease on FNAC. For the participating District General Hospital the sensitivity in distinguishing malignant from benign disease was 38% (95% CI 13-63%) and specificity 95% (95% CI 73-95%). CONCLUSIONS Fine needle aspiration cytology does not reliably distinguish a benign from a malignant primary salivary gland neoplasm in the participating institutions. Where clinical teams use FNAC in an attempt to resolve this clinical problem, the results should be interpreted with caution and an ongoing audit of performance is required.

Abstract
In the last decade, several new promising treatments for chronic lymphocytic leukaemia (CLL) have been developed. Healthcare costs are increasing and new treatments tend to be very expensive; therefore, information about the cost effectiveness in treatments for CLL is urgently needed. The authors performed a literature review on the currently available economic evaluations on CLL treatments. A total of 65 articles were found, of which 11 could be included. These articles were evaluated on the basis of six methodological requirements for economic evaluations, enabling readers to judge the value of the studies. Only a small amount of information was available on the costs of CLL treatments. Future economic evaluations should be performed according to the methodological requirements for these studies, which should also be properly documented.

Abstract
Abstract
Context.—We use data from the College of American Pathologists Interlaboratory Comparison Program in Nongynecologic Cytology to identify common diagnostic errors in salivary gland fine-needle aspiration (FNA).
Objective.—To identify salivary gland FNA cases with poor performance characteristics in the Nongynecologic Cytology Program surveys, so that the most common diagnostic pitfalls can be avoided.
Design.—A retrospective review of the College of American Pathologists Nongynecologic Cytology Program's cumulative data from 1999 to 2003 revealed the most common false-positive and false-negative interpretations on FNA for common salivary gland lesions. Slides that performed poorly were then reviewed to identify the cytologic characteristics that may have contributed to their poor performance.
Results.—A total of 6249 participant responses with general interpretations of benign (n = 4642) or malignant (n= 1607) were reviewed. The sensitivity and specificity of the participant responses for correctly interpreting the cases as benign or malignant were 73% and 91%, respectively. Benign cases with the highest false-positive rates were monomorphic adenoma (53% false-positive), intraparotid lymph node (36%), oncocytoma (18%), and granulomatous sialadenitis (10%). Malignant cases with the highest false-negative rates were lymphoma (57%), acinic cell carcinoma (49%), low-grade mucoepidermoid carcinoma (43%), and adenoid cystic carcinoma (33%). Selected review of the most discordant individual cases revealed possible explanations for some of the interpretative errors.
Conclusions.—These data confirm the difficulty associated with interpretation of salivary gland FNA specimens. Cytologists should be aware of the potential false-positive and false-negative interpretations that can occur in FNAs from this organ site in order to minimize the possibility of diagnostic errors.

Abstract
A 48-yr-old black woman with a history of blood transfusions for menorrhagia secondary to uterine fibroids but no known Caribbean association presented with a 6-wk history of a rapidly enlarging right parotid mass. At the time of presentation, she could not close her right eye. An aspiration biopsy showed small, medium, and large lymphoma cells with angulated nuclei, red macronucleoli, and basophilic cytoplasm with fine vacuoles. Flow cytometry indicated a (CD25(+)/CD7(-)) T-cell lineage, suggesting an human T-lymphotropic virus (HTLV) 1-related T-cell leukemia/lymphoma, which was confirmed by polymerase chain reaction (PCR)-based amplification on DNA extracted from fresh tissue with specific oligonucleotide primers for HTLV-1 DNA sequence. Histology showed interstitial infiltration and destruction of the parotid parenchyma by lymphoma cells without involvement of adjacent lymph nodes. Total body CT scan and magnetic resonance imaging (MRI) studies were negative for lymphadenopathy but showed liver metastasis. To our knowledge, this is the first reported case of HTLV-1-related primary parotid lymphoma as the initial presentation of adult T-cell leukemia/lymphoma.

Abstract
BACKGROUND Low-grade lymphomas can be difficult to diagnose in cytology specimens, especially marginal zone B-cell lymphomas (MZLs). MZL is a low-grade lymphoma characterized by a heterogeneous lymphoid population, which can be difficult to distinguish from reactive processes in cytology specimens. METHODS Fourteen cytology specimens of MZL from 11 patients with histologically confirmed MZL (n = 10) or flow cytometry (FC)-confirmed MZL (n = 1) were reviewed, including 13 fine-needle aspiration biopsy (FNAB) specimens (salivary gland, n = 6; lung, n = 3; lymph node, n = 2; breast, n = 1; and soft tissue, n = 1) and 1 pleural effusion specimen. Cytologic preparations included air-dried and alcohol-fixed direct smears, ThinPrep(R) slides, and cell blocks. FC studies were available in six specimens. RESULTS All 13 FNAB specimens were composed predominantly of intermediate-sized lymphoid cells with interspersed small, round lymphocytes and transformed cells. The intermediate-sized cells displayed a moderate amount of cytoplasm, slight nuclear membrane irregularities, and inconspicuous-to-absent nucleoli. The pleural fluid contained mostly small-to-intermediate-sized, round lymphocytes. In 10 specimens, the intermediate-sized cells often showed plasmacytoid morphology, which were seen best in Diff-Quik (Mercedes Scientific Co., Inc., Sarasota, FL)-stained slides. Monocytoid cells (n = 6 specimens), plasma cells (n = 7), lymphohistiocytic aggregates (n = 11), and tingible body macrophages (n = 5) were variably identified. Lymphoepithelial lesions were not observed. Three specimens with FC studies showed a phenotype compatible with MZL, and three specimens were nondiagnostic. CONCLUSIONS Cytologic features suggestive of MZL included abundant intermediate-sized lymphoid cells with mild atypia in a background of small lymphocytes and transformed cells, often with plasmacytoid morphology. Flow cytometry was beneficial only in selected MZL cytology specimens. Surgical correlation may be necessary to confirm the diagnosis.

Abstract
Fine-needle aspiration biopsy (FNAB) is an accurate, cost-effective method of evaluating lymphomas. The neutrophil-rich variant of anaplastic large cell lymphoma (NR-ALCL) is a rare non-Hodgkin lymphoma. To our knowledge, we present thefirst study of NR-ALCL by FNAB cytology. Histologic confirmation was available for both patients. Both cases were positive for Ki-1 (CD-30) and were either T-cell or null-cell phenotype. FNAB specimens were highly cellular with a single-cell pattern composed of pleomorphic tumor cells, "hallmark" tumor cells, and a background rich in neutrophils that occasionally obscured tumor cells. Diagnosis on FNAB is difficult owing to the rarity of this tumor, its resemblance to Hodgkin lymphoma and other non-Hodgkin lymphomas that express CD30, its similarity to an infectious process, and its occasional confusion with metastatic carcinoma and melanoma. Reproducible cytologic features usually are present, and the diagnosis can be made conclusively by FNAB in conjunction with ancillary studies.

Abstract
Kuttner tumor or chronic sclerosing sialadenitis is a benign inflammatory condition of the submandibular gland that mimics a malignant neoplasm clinically because of presentation as a hard mass. This is an underrecognized entity in the surgical pathology and cytology literature. We describe thefine-needle aspiration cytologic findings of 7 cases with histologic correlation. The 6 men and 1 woman (age, 47-72 years) had unilateral (4 cases) or bilateral (3 cases) submandibular masses known to be present for 1 month to 6 years (mean, 15 months). The aspirates were paucicellular to moderately cellular. They were characterized by scattered tubular ductal structures often enveloped by collagen bundles or lymphoplasmacytic infiltrate, isolated fragments of fibrous stroma, a background rich in lymphoid cells, and paucity or absence of acini. Histologic examination of the excised submandibular glands revealed preserved lobular architecture, thickening of interlobular septa by sclerotic tissue, dense lymphoplasmacytic infiltrate, preservation of ducts with periductal fibrosis, and variable loss of acini. In combination with the clinical findings, the fine-needle aspiration cytologic findings can strongly suggest the diagnosis of Kuttner tumor and may obviate the need of surgical intervention.
