Leng B, Guo M, Zhao J, Gong Y. Utility and pitfalls of GATA3 immunocytochemistry for diagnosis of metastatic breast carcinoma and urothelial carcinoma on cytology specimens. J Am Soc Cytopathol 2017; 6:73-79. [PMID: 31042637 DOI: 10.1016/j.jasc.2016.12.002] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2016] [Revised: 12/21/2016] [Accepted: 12/21/2016] [Indexed: 11/16/2022]
Abstract
INTRODUCTION Although GATA3 expression has been studied extensively on histology specimens and has demonstrated a high level of accuracy in detecting carcinomas from breast or urothelial origin, its utility on cytology samples, especially the influence of different sample (fine-needle aspiration [FNA] versus effusion fluid) and preparation (cell block versus smear) on the staining, is understudied. MATERIALS AND METHODS We retrospectively searched our institution's pathology database for cytologic cases where GATA3 immunostaining was performed during diagnostic workup and identified a total of 178 cases, consisting of 89 metastatic breast carcinomas, 22 metastatic urothelial carcinomas, and 67 malignant neoplasms of other origin. Frequency of GATA3 expression was evaluated in each group. RESULTS For metastatic breast carcinomas, 75% expressed GATA3; 74% on FNA samples and 77% on fluid samples; 71% on cell block and 89% on smear. GATA3 was positive in 44% triple-negative breast carcinomas. Of the 22 metastatic urothelial carcinomas (21 FNA samples and 1 fluid; 21 cell blocks and 1 smear), all were positive for GATA3. Of the 67 malignancies of other origin, 4 (6%) were positive for GATA3 (ie, a metastatic ovarian serous carcinoma, a metastatic squamous cell carcinoma, a recurrent poorly differentiated skin adnexal carcinoma, and a metastatic thymic carcinoma). CONCLUSIONS GATA3 is a useful biomarker for detecting carcinomas of breast or urothelial origin on cytologic specimens. It may detect breast cancers with the triple-negative phenotype. Both cell block and smear preparations can be reliably used for the staining. GATA3-positive immunostaining is occasionally seen in other tumors, which may cause diagnostic confusion.

The Novel Marker GATA3 is Significantly More Sensitive Than Traditional Markers Mammaglobin and GCDFP15 for Identifying Breast Cancer in Surgical and Cytology Specimens of Metastatic and Matched Primary Tumors. Appl Immunohistochem Mol Morphol 2016; 24:229-37.

Abstract
Traditional markers mammaglobin and GCDFP15 show good specificity but lack sensitivity and can be difficult to interpret in small tissue samples. We undertook a comparative study of the novel nuclear marker GATA3 (expression typically restricted to breast and urothelial carcinomas) and GCDFP15 and mammaglobin. We first compared quantitative mRNA expression levels of these 3 markers across a diverse set of over 6000 tumors and 500 normal samples from The Cancer Genome Atlas which showed dramatically higher GATA3 expression (>10-fold higher) in breast cancer as compared with GCDFP15 or mammaglobin (both P<2.2e-16), suggesting that GATA3 may represent a more sensitive marker of breast cancer than GCDFP15 or mammaglobin. We next examined protein expression by immunohistochemistry in 166 cases (including surgical and cytology specimens) of metastatic breast carcinoma and 54 cases with available matched primaries. One whole-slide section from each case was stained for monoclonal GATA3 (L50-823), monoclonal mammaglobin (31A5), and monoclonal GCDFP15 (EP1582Y). Staining intensity (0 to 3+) and extent (0% to 100%) were scored with an H-score calculated (range, 0 to 300). Sensitivities by varying H-score cutoffs for a positive result in metastatic breast carcinoma among GATA3/GCDFP15/mammaglobin, respectively, were as follows: any H-score=95%/65%/78%, H-score>50=93%/37%/47%, H-score>100=90%/25%/27%, H-score>150=86%/21%/19%, H-score>200=73%/18%/9%, H-score>250=66%/14%/6%. Significant staining differences by specimen type, tumor subtype/grade, or ER/PR/HER2 status were not identified. Significantly stronger correlation was observed between primary/metastatic GATA3 expression [Pearson's correlation=0.81 (0.68-0.89)] as compared with the primary/metastatic correlations of GCDFP15 [Pearson's correlation=0.57 (0.33-0.74)] and mammaglobin [Pearson's correlation=0.50 (0.24-0.70)] (both P<0.05). In conclusion, the novel marker GATA3 stains a significantly higher proportion of both primary and metastatic breast carcinomas than GCDFP15 or mammaglobin with stronger and more diffuse staining, helpful in cases with small tissue samples. The matched primary/metastatic expression of GATA3 is also more consistent. We propose that GATA3 be included among a panel of confirmatory markers for metastatic breast carcinoma.

Abstract
Distant metastases are relatively common in breast cancer, but spread to the head and neck region is uncommon and can be diagnostically challenging. Pathology databases of two academic hospitals were searched for patients. The diagnoses were by morphologic comparison with the primary breast specimen (when available) or through the use of immunohistochemical stains characteristic of breast carcinoma (cytokeratin 7, mammaglobin, GCDFP15, and/or GATA3 positive-excluding new primary tumors at the respective head and neck sites). Of the 25 patients identified, only 22 (88.0 %) had a known history of breast carcinoma. Time from primary diagnosis to head and neck metastasis was highly variable, ranging from 1 to 33 years (mean = 10.9 years). The most common locations were neck lymph nodes (8 cases), orbital soft tissue (5), oral cavity (3), skull base (3), mastoid sinus (2), nasal cavity (1), palatine tonsil (1), and facial skin (1). Clinical presentations were highly variable, ranging from cranial nerve palsies without a mass lesion to oral cavity erythema and swelling to bone pain. Histologically, two cases showed mucosal (or skin)-based mass lesions with associated pagetoid spread in the adjacent epithelium, a feature normally associated with primary carcinomas. Three tumors were misdiagnosed pathologically as new head and neck primary tumors. This series demonstrates the extreme variability in clinical and pathologic features of breast cancer metastatic to the head and neck, including long time intervals to metastasis.

Abstract
Despite the fact that accessory spleen (also known as supernumerary spleen, splenunculus, or splenule) can be found in 10–30% of patients undergoing autopsies, metastatic disease occurring in this organ has been barely reported. A case of lobular breast carcinoma metastatic to the spleen and accessory spleen found incidentally at therapeutic splenectomy for severe anemia and thrombocytopenia is described. On microscopic examination both organs revealed severe fibrocongestive changes and extramedullary hematopoiesis with no obvious carcinomatous involvement. Cytokeratin 7, estrogen receptors, and GATA3 immunohistochemistry disclosed the presence of numerous metastatic breast carcinoma cells infiltrating the splenic parenchyma. This case demonstrates that metastatic carcinoma can be encountered, although rarely, in accessory spleens and that cytokeratin stain should be performed in sections of spleens and/or accessory spleens excised from cancer patients in which the presence of malignant epithelial cells is not recognized on routine sections.

Abstract
GATA3 has been recognized as the novel marker for identifying primary and metastatic breast carcinomas, consistently showing that GATA3 was significantly more sensitive than traditional markers gross cystic disease fluid protein 15 (GCDFP15) and mammaglobin (MGB). However, clinically useful groups of breast carcinomas status were not identified, which were determining appropriate treatment strategy, affecting the prognosis. In this study, we undertook a comparative study of the marker GATA3 and GCDFP15 and MGB in clinically useful groups of paired primary and metastatic breast cancer. We retrieved 64 cases of matched primary and metastatic breast cancer from the surgical pathology archive at our institution. According to the emerging 2015 St. Gallen Consensus, the clinically useful groups were divided into ER and/or PR (+), HER2 (-), abbreviated as A; ER and/or PR (+), HER2 (+), abbreviated as B; ER and PR (-), HER2 (+), abbreviated as C; ER, PR and HER2 (-), abbreviated as D; each group contained 16 cases (n=16). Tissue microarrays were created, with three 1-mm punch specimens from each case. The tissue microarrays were cut at 4-μm thickness and stained with monoclonal antibodies to GATA3, GCDFP15, and MGB. Staining intensity (0-3+) and extent (0%-100%) were scored with an H-score calculated (range, 0-300). Sensitivities by varying H-score cutoffs (any; ≥50; ≥150) for a positive result in the clinically useful groups of matched primary or metastatic breast cancer among GATA3, GCDFP15, and MGB. GATA3 was significantly more sensitive than GCDFP15 and MGB A and B groups (P<.05) rather than C and D groups (P>.05). However, GATA3 in conjunction with GCDFP15 and MGB detection could improve the sensitivity of C group (P<.05) rather than D group (P>.05). Significantly, good coincidence was observed between primary and metastatic tumor GATA3 expression (κ value = 0.826 >0.75) as compared with the coincidence of GCDFP15 (κ value =0.492 <0.75) and MGB (κ value =0.593 <0.75) (both P<.05). In conclusion, GATA3 expression did not show the same sensitivity for the clinically useful groups of breast cancer. GATA3 expression is positively correlated with ER-positive, PR-positive, and HER2-positive carcinomas. In addition, the matched primary and metastatic tumor expression of GATA3 shows good coincidence. We propose the careful selection of GATA3 for identifying hormone receptor negativity of breast cancer, especially in the case of triple-negative breast cancer.

Abstract
Although most adrenal tumors are not diagnostic dilemmas, there are cases that are challenging. This may be due to the tissue provided, for example fragmented tissue received in the setting of morcellation, or it may be due to inherently challenging histology, such as in cases with equivocal features of malignancy. Additionally, much has been learned about the molecular alterations of adrenal tumors, especially pheochromocytomas. Many of these alterations represent germline mutations with significant clinical implications for patients and their families. The aim of this review is to provide an overview of the most common adrenal tumors in adults so that pathologists can tackle these interesting tumors.

Abstract
Initial investigations reported GATA3 to be a sensitive and relatively specific marker for mammary and urothelial carcinomas. Recently, GATA3 expression has been described in several other epithelial tumors. However, there has been only limited investigation of GATA3 expression in cutaneous epithelial tumors. The objective of this study was to examine the immunohistochemical expression of GATA3 in a wide variety of cutaneous epithelial neoplasms. GATA3 expression was evaluated in 99 benign and 63 malignant cutaneous epithelial tumors. GATA3 was consistently and usually strongly expressed in clear cell acanthoma, trichofolliculoma, trichoepithelioma, trichilemmoma, sebaceous adenoma, sebaceoma, apocrine hidrocystoma, apocrine tubular papillary adenoma, hidradenoma papilliferum, and syringocystadenoma papilliferum. Hidradenomas exhibited variable positive staining. Most poromas, syringomas, chondroid syringomas, cylindromas, and spiradenomas were negative or only focally and weakly positive. Focal staining was present in all pilomatrixomas. Thirteen of 14 basal cell carcinomas, 21 of 24 squamous carcinomas, and all 6 sebaceous carcinomas exhibited positive staining. The 1 apocrine carcinoma, both mucinous carcinomas, and 2 of 3 microcystic adnexal carcinomas also exhibited positive staining, whereas the 1 eccrine porocarcinoma and the 1 adenoid cystic carcinoma were negative. One of 11 Merkel cell carcinomas exhibited focal weak staining. Our findings demonstrate that GATA3 is expressed in a wide variety of benign and malignant cutaneous epithelial neoplasms. In addition to carcinomas of breast and urothelial origin and other more recently described GATA3-positive tumors, the differential diagnosis of a metastatic tumor of unknown primary origin that expresses GATA3 should also include a carcinoma of cutaneous epithelial origin.

Abstract
BACKGROUND & AIMS Less than 10% of registered drug intervention trials for pancreatic ductal adenocarcinoma (PDAC) include a biomarker stratification strategy. The ability to identify distinct mutation subsets via endoscopic ultrasound fine needle aspiration (EUS FNA) molecular cytology could greatly aid clinical trial patient stratification and offer predictive markers. We identified chemotherapy treatment naïve ampullary adenocarcinoma and PDAC patients who underwent EUS FNA to assess multigene mutational frequency and diversity with a surgical resection concordance assessment, where available. METHODS Following strict cytology smear screening criteria, targeted next generation sequencing (NGS) using a 160 cancer gene panel was performed. RESULTS Complete sequencing was achieved in 29 patients, whereby 83 pathogenic alterations were identified in 21 genes. Cytology genotyping revealed that the majority of mutations were identified in KRAS (93%), TP53 (72%), SMAD4 (31%), and GNAS (10%). There was 100% concordance for the following pathogenic alterations: KRAS, TP53, SMAD4, KMT2D, NOTCH2, MSH2, RB1, SMARCA4, PPP2R1A, PIK3R1, SCL7A8, ATM, and FANCD2. Absolute multigene mutational concordance was 83%. Incremental cytology smear mutations in GRIN2A, GATA3 and KDM6A were identified despite re-examination of raw sequence reads in the corresponding resection specimens. CONCLUSIONS EUS FNA cytology genotyping using a 160 cancer gene NGS panel revealed a broad spectrum of pathogenic alterations. The fidelity of cytology genotyping to that of paired surgical resection specimens suggests that EUS FNA represents a suitable surrogate and may complement the conventional stratification criteria in decision making for therapies and may guide future biomarker driven therapeutic development.

Abstract
AIMS To report 18 yolk sac tumours (YSTs) of the female genital tract (17 ovary, one uterus) in patients aged 40 years or over, most arising from a somatic epithelial neoplasm. METHODS AND RESULTS Six patients had pure YST, two were associated with immature teratoma (one with an endometrioid adenocarcinoma) and in 11 there was an epithelial neoplasm comprising high-grade serous carcinoma (HGSC) (n = 5), clear cell carcinoma (n = 1), borderline clear cell adenofibroma (n = 1), endometrioid adenocarcinoma (n = 2), serous tubal intra-epithelial carcinoma (n = 1) and large-cell neuroendocrine carcinoma (n = 1). In one case of pure YST, there was an ipsilateral endometriotic cyst but no other neoplastic component. In two cases, the YST was a hepatoid variant and in most of the others it exhibited predominantly glandular morphology, closely mimicking an epithelial neoplasm. CONCLUSIONS Pathologists should be aware of the association between YST and an epithelial neoplasm, the former probably arising from the latter through a process of neometaplasia/retrodifferentiation. Those rare gynaecological pure glandular YSTs in adults may arise secondary to total overgrowth of an epithelial neoplasm. Pathologists need a high index of suspicion to diagnose the YST component, as the morphology is characteristically of a glandular variant with marked morphological overlap with adenocarcinomas. There is also often significant immunophenotypical overlap with epithelial neoplasms, as the YST component may be positive with epithelial membrane antigen (EMA), BerEP4 and cytokeratin 7 (CK7), as well as YST markers. We propose the term 'somatically derived YSTs' for these neoplasms and suggest unification of the terminology between different sites where such neoplasms occur.

Comparison of metastatic neuroendocrine neoplasms to the breast and primary invasive mammary carcinomas with neuroendocrine differentiation. Mod Pathol 2016; 29:788-98. [PMID: 27125358 DOI: 10.1038/modpathol.2016.69] [Citation(s) in RCA: 42] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2015] [Revised: 02/24/2016] [Accepted: 03/06/2016] [Indexed: 12/29/2022]
Abstract
Metastatic neuroendocrine neoplasms to the breast may show considerable morphologic overlap with primary mammary carcinomas, particularly those showing evidence of neuroendocrine differentiation, and may be misdiagnosed as such. Accurate distinction between these two entities is crucial for determination of appropriate clinical management. The histologic and immunohistochemical features of metastatic neuroendocrine neoplasms to the breast were studied and compared with the features of primary invasive mammary carcinomas with neuroendocrine differentiation, which served as controls. Of the metastatic neuroendocrine neoplasms, 15 were well-differentiated neuroendocrine tumors with carcinoid tumor-type morphology and 7 were poorly differentiated/high-grade neuroendocrine carcinomas with small-cell or large-cell neuroendocrine carcinoma morphology. The majority of the metastatic neoplasms originated in the lung and gastrointestinal tract. There were histologic similarities between metastatic neuroendocrine neoplasms and invasive mammary carcinomas with neuroendocrine differentiation, both of which exhibited neuroendocrine histologic features (nested and trabecular architecture, minimal tubular differentiation, and characteristic nuclear features). Only one case of the invasive mammary carcinomas with neuroendocrine differentiation was modified Bloom-Richardson grade 1 (largely due to minimal tubular differentiation on most such tumors), and the invasive mammary carcinomas with neuroendocrine differentiation were often associated with in situ carcinoma. Immunohistochemistry was helpful in distinguishing metastatic neuroendocrine neoplasms from invasive mammary carcinomas with neuroendocrine differentiation. Whereas the majority of invasive mammary carcinomas with neuroendocrine differentiation were positive for estrogen receptor and GATA3, metastatic neuroendocrine neoplasms were typically negative for estrogen receptor and GATA3, and metastatic well-differentiated neuroendocrine tumors often showed immunoreactivity for site-specific markers. Although the histologic and immunohistochemical features of a breast tumor may raise the suspicion of a metastatic neuroendocrine neoplasm, the pathologic findings should be interpreted in the context of the clinical history and imaging findings in order to establish an accurate diagnosis.

Abstract
Pan-cancer analyses attempt to discover similar features among multiple cancers to identify fundamental patterns common to cancer development and progression. A pan-cancer analysis integrating both protein expression and transcriptomic data is important because it can identify genes that are linked to proteins potentially responsible for a patient's status. This study aims to identify differentially expressed (DE) genes between early and advanced cases of multiple cancer types through the usage of RNA sequencing data. The relevance of these genes is further investigated by developing predictive models using K-nearest neighbor and linear discriminant analysis classifiers. The use of cancer-specific and non-cancer specific features resulted in several moderately performing models. Highlighted genes were further investigated to determine if they encoded for proteins identified in a previously conducted pan-cancer analysis. The results of this study suggest that a pan-cancer analysis may be highly complementary to standard analyses of individual cancers for identifying biologically relevant DE genes and can assist in developing effective predictive models for cancer progression.

Abstract
Parathyroid and thyroid lesions appear morphologically similar in cytological smears, and their differentiation can be difficult. The purpose of this study was to determine the diagnostic value of T-cell-specific transcription factor GATA-3 as a marker of parathyroid differentiation in cytology specimens, and to examine the utility of liquid-based cytology (LBC). Cytology smears obtained from surgically removed parathyroid and thyroid specimens, including 15 normal parathyroid glands, 12 cases of parathyroid hyperplasia, 55 parathyroid adenomas, 2 follicular thyroid adenomas, and 3 papillary thyroid carcinomas, were examined by immunocytochemistry using antibodies against GATA-3, parathyroid hormone (PTH), chromogranin A, and thyroid transcription factor 1 (TTF-1). All normal and hyperplastic parathyroids and 98.2% of parathyroid adenomas were positive for GATA-3, while 33.3%, 66.7%, and 60.0% of them, respectively, were positive for PTH. The positive rates for chromogranin A among normal parathyroids (80.0%) and parathyroid adenomas (87.3%) were lower than those for GATA-3. At the same time, all thyroid-derived tumours were positive for TTF-1 and negative for GATA-3, PTH, and chromogranin A. LBC smears of 35 parathyroid lesions indicated that the positive rates for GATA-3, PTH, and chromogranin A were 97.1 %, 97.1%, and 100%, respectively, while in conventional smears, those for PTH (25.5%) and chromogranin A (78.7%) were significantly lower (p < 0.01). Our results suggest that GATA-3 is a more reliable biomarker than PTH or chromogranin A in differentiating parathyroid from thyroid lesions in cytology smears and that LBC is useful in detecting cytoplasmic antigens such as PTH and chromogranin A.

Abstract
BACKGROUND GATA-3 is a transcription factor involved in human tissue growth and differentiation. It is a potential marker for breast carcinoma origin in metastasis and predictive of good prognosis. We aim to evaluate the role of GATA3 in determining the breast origin of metastatic adenocarcinoma in malignant effusions using immunohistochemistry on cell-block microarray in comparison with ER and PR results. METHODS Cell blocks from 100 cases of malignant and reactive serous effusions with confirmed diagnosis were selected; 28 mammary carcinomas, 64 extra-mammary adenocarcinomas (gastrointestinal, pulmonary, gynecologic), and 8 reactive mesothelium proliferation as control. Immunohistochemistry on cell-block microarray was used. Microarray slides were stained for GATA-3, ER and PR. Nuclear staining of >1% was considered positive. RESULTS GATA3, ER and PR were positive in 25 (89%), 20 (71%) and 16 (57%) of breast carcinoma cases, respectively. All non-breast cancer cases were negative for GATA-3 with the exception of one Müllerian adenocarcinoma (1.6%). The calculated sensitivity, specificity and positive predictive value (PPV) of GATA3 reactivity in determining the breast origin of metastatic adenocarcinoma was 89.3% (95% CI: 71.7-97.7%), 98.6% (95% CI: 91.6-99.9%) and 96.2% (95% CI: 80.4-99.9%), respectively. GATA3 positivity was associated with ER or PR positivity in 84% of cases. CONCLUSIONS GATA3 is a useful marker in determining the breast origin of metastatic adenocarcinoma in malignant serous effusions. Reactivity to GATA3 may indicate good prognosis. Diagn.

Abstract
Background Breast cancer is a common malignancy, but metastases to the breast of extramammary malignancies are very rare. Treatment and prognosis are different. The aim of the study is to report the incidence of lymphomas and metastases to the breast of extramammary malignancies in our 30-year archive. Methods The pathology database of a single institute was reviewed for all breast neoplasms which were coded in our system as a metastasis in the period 1985–2014. Metastatic tumors from primary breast carcinoma were excluded. Results A total of 47 patients were included (7 men/40 women, mean age 63 years). The majority originated from lymphoma (n = 18) and primary melanoma (n = 11). Other primary tumor sites included the ovary (n = 6), lung (n = 6), colon (n = 3), kidney (n = 1), stomach (n = 1), and chorion (n = 1). In 24/47 patients (51 %), metastasis was the first sign of the specific malignant disease. In seven patients (15 %) surgery was performed, the diagnosis of metastatic disease was adjusted in four patients (9 %) postoperatively. Conclusions It is important to distinguish lymphomas and metastases to the breast from common primary breast carcinoma for proper treatment and prognosis. Therefore, we emphasize the need for a histological or cytopathological diagnosis before any treatment is commenced. The pathologist plays a key role in considering the diagnosis of metastasis if the histological features are unusual for a primary breast carcinoma. The pathologist should therefore be properly informed by the clinical physician although lymphomas and metastases to the breast are the first presentation of malignant disease in half the cases.

Abstract
OBJECTIVE Recent studies have investigated the significance of GATA3 expression in patients with various malignant tumors. However, no previous studies have evaluated the clinicopathological importance of GATA3 expression in soft tissue sarcomas (STS) patients. METHODS We evaluated GATA3 expression in 76 STS cases using immunohistochemical analysis, and statistically compared clinicopathological characteristics between GATA3-positive and GATA3-negative cases. RESULT GATA3-positive expression was significantly associated with a higher mitotic count (P < 0.0001). Disease-free survival (DFS) of GATA3-positive cases was significantly shorter than that of cases without GATA3 expression (P = 0.0104). Overall survival (OS) of GATA3-positive cases was significantly shorter than that of cases without GATA3 expression (P = 0.0006). GATA3-positive expression was significantly associated with shorter DFS in both univariate analysis (hazard ratio [HR], 2.719; P = 0.012) and multivariate analysis (HR, 2.711; P = 0.014). GATA3-positive expression was also significantly associated with worse OS in both univariate analysis (HR, 5.730; P = 0.0007) and multivariate analysis (HR, 5.789; P = 0.0008). CONCLUSION These results indicate that GATA3 is an independent prognostic factor and suggest that evaluation of GATA3 expression might enable more effective clinical follow-up using prognostic stratification of STS patients.

Abstract
GATA-binding protein 3 (GATA3) is a diagnostically useful immunohistochemical marker of breast cancer. Because of its strong association with estrogen receptor expression, GATA3 has markedly reduced sensitivity in triple-negative breast cancer (TNBC). We constructed a tissue microarray using a large series of TNBCs and evaluated GATA3 expression by TNBC subtype as defined by surrogate immunohistochemical markers. A total of 205 TNBCs were classified into cancers of the molecular apocrine type (n=23, 11.2%), claudin-low type (n=21, 10.2%), basal-like type (n=91, 44.4%), mixed type (n=62, 30.2%), and null type (n=8, 3.9%). The GATA3 scores (staining intensity × proportion) were categorized as negative (0), focally positive (1-10), or positive (11-300). GATA3 staining was negative in 153 cancers (74.6%), focally positive in 11 (5.4%), and positive in 41 (20.0%). The rate of focal positivity or positivity for GATA3 was significantly higher in the molecular apocrine type (73.9%, 17/23) than in other types of TNBCs (P=.001). The mean GATA3 score of molecular apocrine-type TNBC was significantly higher than that of the other types (P=.001) and differed significantly between androgen receptor (AR)-positive and AR-negative TNBCs (P<.001). In conclusion, GATA3 expression was correlated strongly with AR-positive, molecular apocrine-type TNBCs. Co-expression of AR and GATA3 is a specific feature of molecular apocrine-type TNBC, which may serve as a diagnostic aid for cancer of unknown primary.

Abstract
GATA binding protein 3 (GATA3) is a recently described immunohistochemical marker that has proven useful in the characterization of breast and urothelial carcinomas. However, the expression pattern of GATA3 in mesonephric proliferations is largely unknown. The aim of this study was to examine the immunohistochemical expression of GATA3 in cervicovaginal mesonephric lesions and compare it to its expression in endocervical and endometrial adenocarcinomas and cervicovaginal endometriosis. A cohort of 107 cases, including 33 cases of mesonephric lesions and 74 cases of nonmesonephric lesions, was selected for the study. Of 33 mesonephric lesions, 31 (94%) cases (16 remnants, 12 hyperplasias, and 3 adenocarcinomas) were strongly and diffusely positive in tumor cell nuclei for GATA3. The remaining 2 mesonephric carcinosarcomas showed focal nuclear staining and rare nuclear positivity, respectively. Of 36 endocervical adenocarcinomas, 33 (92%) were negative for GATA3 and the remaining revealed focal weak nuclear staining. Of 34 endometrial adenocarcinomas, 32 (94%) were negative, whereas 2 showed rare nuclear positivity. All 4 cases of endometriosis were negative. The benign endocervical epithelium and the benign endometrium in most cases lacked GATA3 expression, whereas the benign squamous epithelium in the majority exhibited nuclear basal and parabasal staining pattern. Our study demonstrates that GATA3 protein is expressed in most mesonephric lesions, regardless of them being benign or malignant. In contrast, GATA3 is absent in the majority of endometrial and endocervical adenocarcinomas. These results support that GATA3 immunostain can be a useful tool in differentiating mesonephric lesions from endocervical and endometrial adenocarcinomas.

Abstract
Metastatic involvement of the prostate from noncontiguous solid tumors is a rare event occurring by means of vascular dissemination. The reported cases of biopsy and surgical samples with metastatic involvement have increased; however, a comprehensive understanding of secondary tumors of the prostate is currently missing. Metastases to the prostate carry a dismal prognosis and may pose serious diagnostic challenges to both clinicians and pathologists, with crucial therapeutic implications. Secondary tumors of the prostate spread more frequently from the digestive tract, the lung, and the kidney. The integration of clinicoradiologic data with appropriate pathologic and immunohistochemical analyses is essential for the identification and the characterization of secondary tumors of the prostate, whereas molecular analyses could provide additional and complementary information, enabling precise diagnosis and appropriate clinical management. Patients with solitary metastases could benefit from prostatic resection and adjuvant therapy, whereas in cases of disseminated diseases, symptom control may be obtained with palliative procedures. The purpose of this review was to assess the current state of knowledge of secondary tumors involving the prostate gland and to discuss short-term future perspectives, while providing a practical approach to these uncommon conditions for pathologists and oncologists.

Abstract
Uterine cervical carcinoma secondarily involving the genitourinary tract is rarely documented histologically. These tumors present a unique diagnostic challenge as they can appear morphologically similar to urothelial carcinoma as well as primary squamous cell carcinoma and primary adenocarcinoma of the bladder. Genitourinary consult cases at the Johns Hopkins Hospital from 1984 to the present were searched for cases in which the differential diagnosis was primary bladder carcinoma versus secondary involvement by cervical carcinoma. We identified 10 cases that met these criteria and evaluated them by immunohistochemistry for p16 and GATA3 and in situ hybridization for human papillomavirus (HPV). Six cases were received with a gynecologic history. Four cases had been misdiagnosed as urothelial carcinoma, and 1 case was favored to be cystitis cystica et glandularis by the submitting institutions. Morphologically, the majority of cases showed basaloid nests of tumor cells infiltrating muscle bundles, with several having foci that mimicked urothelial carcinoma in situ. Six tumors were found to be diffusely positive with p16, 1 tumor was patchy, 1 was weak, and 2 were negative. GATA3 staining was negative in 6 cases, and 4 showed weak to strong positivity. Eight cases were positive for high-risk HPV (6 were positive for HPV 16, and 1 was positive for HPV 18). In the 2 cases that were negative for HPV by in situ hybridization, characteristic morphologic features of HPV-unrelated type of endocervical adenocarcinoma were present. On the basis of our findings we advocate a multifaceted approach, combining morphologic evaluation with ancillary studies including immunohistochemistry and in situ hybridization in the evaluation of genitourinary specimens for secondary involvement by cervical carcinoma. Furthermore, gynecologic clinical history is absolutely critical and most important to the evaluation and diagnosis of these specimens, as these ancillary studies are not completely sensitive or specific.

Abstract
BACKGROUND Fine-needle aspiration (FNA) is well-established as an accurate technique for the diagnosis of palpable breast masses. While the differential diagnosis of such lesions usually focuses on benign or malignant mammary proliferations, a subset of breast neoplasms arises from skin and soft tissue. Skin adnexal neoplasms such as hidradenoma can pose a particular pitfall on breast FNA cytology (FNAC) as epithelial proliferations that are not of ductal or lobular origin. CASE A 59-year-old female presented with a superficial breast mass. FNAC revealed a hypercellular lesion with marked nuclear atypia that was highly suspicious for carcinoma. However, at partial mastectomy, the histological features of the tumor were consistent with atypical hidradenoma. Negativity for estrogen receptor (ER) and progesterone receptor (PR) confirmed the diagnosis. Eighteen years later, the patient remains free of recurrence or metastasis. CONCLUSIONS This report offers the first description of findings of atypical hidradenoma on FNAC. In the breast, its high cellularity and nuclear atypia can mimic a primary mammary carcinoma on FNAC. Although breast and skin adnexal tumors show a immunohistochemical overlap, negative ER and PR stains in a low-grade tumor can suggest a nonmammary lesion. Skin adnexal neoplasms should be considered in the differential diagnosis of superficial breast tumors.

Abstract
BACKGROUND The GATA family of transcription factors is an essential regulator of cellular proliferation and differentiation. In the skin, GATA-3 is critical for epidermal stratification and maintenance of barrier function. A role for GATA-3 in the development of human cutaneous squamous cell carcinoma (SCC) is not known. Here, we investigated GATA-3 immunohistochemical staining in premalignant and invasive cutaneous SCC from sun-exposed and sun-protected skin. METHODS GATA-3 immunohistochemistry was performed on actinic keratoses (AK) (n = 19), in situ squamous cell carcinomas with actinic [SCCIS (A)] (n = 9) or bowenoid features [SCCIS (B)] (n = 17), well-, moderately and poorly differentiated SCC (n = 36), Bowenoid papulosis of the perineum (n = 15) and penile SCC (pSCC) (n = 10). RESULTS We found that GATA-3 immunohistochemical staining is progressively lost in sun-exposed skin as neoplasia progresses from pre-cancerous AK to SCCIS (A), and ultimately, to SCC, which shows near absent GATA-3 staining. This reduction in GATA-3 staining is independent of histological grade in SCC. Only slight down-regulation of GATA-3 was seen in all cases of SCCIS (B) and Bowenoid papulosis, while near absent GATA-3 expression was seen in pSCC. CONCLUSION We propose that decreased GATA-3 immunohistochemical staining is associated with cutaneous SCC progression on both sun-exposed and sun-protected sites.

Abstract
BACKGROUND Although HPV-related head and neck squamous cell carcinoma (HNSCC) has good prognosis, a small proportion of patients develop distant metastases and have worse outcomes. Such metastases can be particularly difficult to diagnose in the lung and mediastinum, where they show extensive morphologic overlap with primary pulmonary neoplasms. This case series discusses metastatic HPV-related HNSCC in lung and mediastinal fine needle aspiration (FNA) cytology. METHODS The cytopathology archives were searched for lung and mediastinal FNA specimens of patients with HNSCC. Specimens were included if either the index FNA or the patient's original HNSCC was positive for HPV by DNA in-situ hybridization (ISH). Ten such cases were identified. Patient demographics and primary tumor details were tabulated from the electronic medical record. All FNA slides and stains were reviewed. RESULTS The ten patients (mean age of 58.2 years) included 4 smokers. Smears from all cases were hypercellular and hyperchromatic, with focal keratinization in 6/10 (60%). Core biopsies and cell blocks showed basaloid morphology with variable amounts of necrosis. All ten FNAs were diffusely positive for p16 (100%) and 7/9 cases stained (77.8%) were positive for HPV DNA ISH. CONCLUSIONS Metastatic HPV-related HNSCC to the lung and mediastinal lymph nodes share the characteristic basaloid, minimally keratinizing morphology seen in Primary HNSCC cytology. Poorly differentiated pulmonary squamous cell carcinoma and neuroendocrine carcinomas are the primary differentials. Although primary lung neoplasms are not HPV-related, p16 positivity can be seen in both squamous cell and small cell lung carcinomas. HPV ISH allows definitive diagnosis of metastatic HPV-related HNSCC.

Abstract
Although most malignant lymphadenopathy in the neck represent lymphomas or metastases from head and neck primary tumors, occasionally, metastatic disease from remote, usually infraclavicular, sites presents as cervical lymphadenopathy with or without an obvious primary tumor. In general, these tumors metastasize to supraclavicular lymph nodes, but occasionally may present at an isolated higher neck level. A search for the primary tumor includes information gained by histology, immunohistochemistry, and evaluation of molecular markers that may be unique to the primary tumor site. In addition, 18F-fluoro-2-deoxyglocose positron emission tomography combined with CT (FDG-PET/CT) has greatly improved the ability to detect the location of an unknown primary tumor, particularly when in a remote location. Although cervical metastatic disease from a remote primary site is often incurable, there are situations in which meaningful survival can be achieved with appropriate local treatment. Management is quite complex and requires a truly multidisciplinary approach. © 2015 Wiley Periodicals, Inc. Head Neck 38: E2374-E2385, 2016.

Abstract
GATA3 is a transcription factor critical for embryogenesis, development, and cell differentiation. Recent studies have suggested that GATA3 is a sensitive and relatively specific biomarker for urothelial and breast carcinomas, with most Müllerian carcinomas being negative. We investigated GATA3 expression in mesonephric/Wolffian remnants and tumors in the female genital tract. A western blot was performed to assess specificity for the GATA3 antibody. GATA3 immunohistochemistry was performed on 59 formalin-fixed paraffin-embedded mesonephric samples, including 17 mesonephric remnants (MR; 11 cervical and 6 fallopian tube), 15 mesonephric hyperplasias, 21 mesonephric carcinomas, and 6 female adnexal tumors of probable Wolffian origin. Thirty conventional endocervical adenocarcinomas (ENDO-CA), 9 gastric-type cervical adenocarcinomas, and 165 endometrial adenocarcinomas (EM-CA) were also evaluated. GATA3 nuclear intensity and extent of staining was evaluated. The western blot revealed GATA3 expression in seminal vesicle and cell lines derived from breast and urothelial carcinomas, but not in other cell lines including ovarian, cervical, and endometrial cancers. All cervical MRs and mesonephric hyperplasias, 5/6 (83%) fallopian tube MRs, and 20/21 (95%) mesonephric carcinomas were GATA3 positive, although with great variability in both intensity (weak to strong) and extent (1+ to 3+) of staining. Only 1/6 (17%) female adnexal tumors of probable Wolffian origin showed weak multifocal staining. One of 30 (3%) usual-type ENDO-CAs and 3/165 EM-CAs exhibited weak-moderate GATA3 immunoreactivity; all gastric-type cervical adenocarcinomas were negative. GATA3 is a highly sensitive and specific marker for mesonephric lesions in the lower genital tract; however, its utility in the upper genital tract may be more limited. In addition, GATA3 can aid in distinguishing lower genital mesonephric lesions from usual-type and gastric-type ENDO-CAs and uterine EM-CAs.

Abstract
Primary angiosarcoma of the bladder is very rare, with approximately 30 cases reported in the literature. Those with epithelioid morphology are even rarer, with only single-case reports published. We describe the histopathologic features and clinical follow-up of 9 patients with epithelioid angiosarcoma (EA) of the bladder retrieved from our Surgical Pathology files from 1998 to 2014. Eight cases were consults. The mean age at presentation was 65 years (range, 39 to 85 y). The M:F ratio was 8:1. The clinical presentation was hematuria and bladder mass in all cases. Six patients had a history of radiotherapy to the pelvis, 5 to treat prostate cancer and 1 to treat uterine cervical cancer. The time from radiotherapy to the diagnosis of EA ranged from 6 to 15 years. The average size of the tumor was 4 cm. (range, 1 to 8 cm.). The submitting diagnoses were poorly differentiated carcinoma (n=5), high-grade invasive urothelial carcinoma (n=3), and atypical vascular proliferation (n=1). Morphologically, the tumors were composed of nests and sheets of highly atypical cells with high nuclear to cytoplasmic ratio, occasional intracytoplasmic lumens, and a hemorrhagic background. None of the cases showed any urothelial carcinoma component. Three patients showed in addition usual angiosarcoma in the resection specimen. By immunohistochemistry, 5/9 cases were positive for cytokeratins, including CK7 (n=3), AE1/AE3 (n=3), and Cam5.2 (n=1). All cases were positive for at least 1 endothelial marker, including CD31 (n=7), CD34 (n=2), FVIII (n=3), and ERG (n=2). Urothelial markers (p63 and GATA3) were consistently negative. Surgical treatment included transurethral resection of the bladder (TURB) only (n=5), TURB followed by cystoprostatectomy (n=2), TURB followed by partial cystectomy (n=1), and cystoprostatectomy only (n=1). The tumor involved the muscularis propria in 5/9 patients, the periureteric adipose tissue in 1 patient, and the prostate and seminal vesicles in 1 patient. Five of 9 patients died of disease, with a median survival of 7 months (range, 6 to 14 mo). Two patients were alive with disease at 3 and 6 months of follow-up. One patient who underwent radical cystoprostatectomy was alive with no evidence of disease 12 months after surgery. EA of the bladder is a rare malignancy that is frequently misdiagnosed as high-grade carcinoma, especially due to positive immunostaining for cytokeratins. This tumor is more frequent in older men with a history of radiotherapy to the pelvis. Morphologic features that should suggest the vascular origin of the tumor include highly atypical nuclei with interspersed erythrocytes, hemorrhagic background, and occasional intracytoplasmic lumens. Patients usually present with muscle invasive disease, and the prognosis is dismal.

Abstract
In the past several years, modifications have been made to the original Gleason system with resultant therapeutic and prognostic implications. Several morphologic variants of prostatic adenocarcinoma have also been described. Prostate pathology has also evolved over the years with the discovery and utility of new immunohistochemical stains. The topics discussed in this update include the Gleason grading system, prognostic grade grouping, variants of prostatic adenocarcinoma, and the application of immunohistochemistry to prostate pathology.

Abstract
INTRODUCTION Tumor collision is the encounter of two tumors from two different topographical sites. Cases of metastatic lymph node collision are exceptional. We report the case of a metastatic lymph node collision of an urothelial carcinoma and a prostatic adenocarcinoma. OBSERVATION A 61-year-old man was hospitalized for a right nephroureterectomy with peri-ureteral lymph node dissection. He was followed since 2004 for prostatic adenocarcinoma and treated with radical prostatectomy then radiation therapy 4 years later due to a new increase of PSA. In the follow-up, an urothelial carcinoma of the lower right ureter was discovered in 2014. Histological analysis of a peri-ureteral lymph node showed a double metastasis of urothelial and prostatic origin. The prostatic adenocarcinoma was composed of acinar and ductal subtypes. Immunohistochemical study including CK7, CK20, PSA, GATA3, P63 antibodies confirmed the distinct phenotype of the 2 tumors. DISCUSSION Metastatic collision of urothelial carcinoma and prostatic adenocarcinoma has been reported in 4 cases only. Our review of literature shows that prostatic adenocarcinoma always precedes the urothelial carcinoma. Immunohistochemical study, when carried out for distinguishing both tumors, should include CK7, CK20 and PSA. GATA3, androgen receptor and P63 could be added in a second time.

Abstract
There are a few studies that have evaluated a panel of stains on a single large data set of breast cancers, which is required for direct comparison between antibodies. The immunohistochemical panel in this study was chosen to include breast-specific markers and markers that are expressed in tumors resembling breast cancer. The individual marker positivity in decreasing order was 95% (177/186) for GATA-3, 92% (172/186) for cytokeratin (CK)7, 80% (151/189) for AR, 80% for estrogen receptor (158/198), 69% for progesterone receptor (137/198), 55% (105/190) for NY-BR-1, 52% (99/189) for mammaglobin, 31% (59/191) for vimentin, 26% (51/195) for GCDFP-15, 0.5% (1/186) for CK20, and 0% (0/188) for PAX-8. When tumors were categorized based on estrogen receptor and HER2 status; a total of 45 profiles were identified. In addition, some tumors showed an unconventional profile-although the majority of breast carcinomas were CK7-positive/CK20-negative, a CK7-negative/CK20-negative profile was seen in ∼8% of the cases. Such a profile can create confusion in investigation of a carcinoma of unknown origin. The results define the individual sensitivity of each marker and establish a baseline diagnostic profile of breast cancer in a large data set. In addition, the results support the use of immunohistochemical panel for confirming or determining breast as the source of metastasis.

Abstract
The diagnosis of cutaneous adnexal neoplasms, a heterogeneous group of entities, is often perceived by practising pathologists as challenging. A systematic approach to diagnosis is necessary for classification of these lesions, which establishes the tumour differentiation (follicular, sebaceous, sweat gland or apocrine) and evaluates histological features differentiating between benign and malignant entities. Consideration of clinical history is a necessary adjunct in evaluation of the adnexal neoplasm, as characteristic anatomical sites are described for many adnexal lesions. In some instances, immunohistochemical studies may also be employed to aid the diagnosis. The differential diagnosis between primary cutaneous adnexal neoplasms and cutaneous metastases from visceral tumours may also be difficult. Clinical, radiological, histological and immunohistochemical characteristics will be further discussed, considering that the correct diagnosis has a significant impact on the patient's management and prognosis.

Abstract
GATA3 is a zinc-binding transcription factor that regulates the differentiation of many human tissue types, including the mammary gland. In surgical pathology, immunohistochemistry for GATA3 is largely used to support urothelial or breast origin in a carcinoma of unknown origin. GATA3 is sensitive but not entirely specific in this setting. Although GATA3 labeling is highest in estrogen receptor-positive carcinomas, it also labels estrogen receptor-negative carcinomas and thus has particular diagnostic utility in the setting of triple-negative breast carcinomas, which are typically negative for other mammary-specific markers.

Abstract
CONTEXT -Identification of the site of origin of carcinoma of unknown primary using immunohistochemistry is a frequent requirement of anatomic pathologists. Diagnostic accuracy is crucial, particularly in the current era of targeted therapies and smaller sample sizes. OBJECTIVES -To provide practical guidance and suggestions for classifying carcinoma of unknown primary using both proven and new antibodies, as well as targeting panels based on integration of morphologic and clinical features. DATA SOURCES -Literature review, the authors' practice experience, and authors' research. CONCLUSIONS -With well-performed and interpreted immunohistochemistry panels, anatomic pathologists can successfully identify the site of origin of carcinoma of unknown primary. It is crucial to understand not only the diagnostic uses of the many available antibodies but also the potential limits and pitfalls.

Abstract
OBJECTIVES The distinction between metastatic breast carcinomas (BCs) and primary lung carcinomas (PLCs) can be difficult. This study tested the utility of trefoil factor 1 (TFF1) for this purpose and compared it with mammaglobin and GATA protein binding 3 (GATA-3). METHODS Tissue microarrays containing 365 BCs and 338 PLCs were stained with TFF1, mammaglobin, and GATA-3, and an H-score was calculated. Sensitivity, specificity, and accuracy were calculated, and logistical regression analysis was performed. RESULTS Accuracy of correctly classifying the tumor type was 81.9%, 71.3%, and 64.0% for GATA-3, mammaglobin, and TFF1, respectively. Odds ratios for selecting BCs were 25.69, 93.15, and 4.17, respectively, with P values less than .001. With a single exception, the best immunopanel included GATA-3 and mammaglobin in all comparisons. CONCLUSIONS TFF1 demonstrated breast specificity but was inferior to mammaglobin and GATA-3. Therefore, its routine clinical use may not be justified. TFF1 showed little benefit when added to an immunopanel.
