BACKGROUND: Loss of BAP1 has recently been described as a highly specific marker for distinguishing malignant mesotheliomas (MM) from benign mesothelial proliferations (BMP). The aim of this study was to evaluate the utility of BAP1 in cytospin and cell block (CB) preparations. METHODS: We searched the database at our institution for cases of MM (n = 21) and BMP (n = 11). A Papanicolaou stained cytospin preparation and CB section from each case were selected for BAP1 staining...

BACKGROUND: Pancreatic tumors often represent primary neoplasms, however organ involvement with metastatic disease can occur. The use of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) to determine the underlying pathology provides guidance of clinical management. METHODS: 25 cases were identified in a retrospective review of our institution's records from 2006 to 2016. Clinical parameters and prognosis are described. RESULTS: Metastatic lesions to the pancreas diagnosed by EUS-FNA accounted for 4...

Cribriform adenocarcinoma of minor salivary gland (CAMSG) is a rare tumor of the head and neck. We report a case of a 70-year-old female who presented with a 4-5-month history of a left neck mass. CT scan of the neck showed a left neck mass just inferior to the angle of the mandible and left tonsillar prominence. Fine-needle aspiration (FNA) of the neck mass showed epithelial groups with focal cribriform architecture. The cells had round to oval nuclei and fine chromatin. The background contained scattered lymphocytes...

BACKGROUND: The cytology of oral squamous cell carcinoma (SCC) is challenging because oral SCC cells tend to be well differentiated and lack nuclear atypia, often resulting in a false negative diagnosis. The purpose of this study was to establish practical cytological parameters specific to oral SCCs. METHODS: We reviewed 123 cases of malignancy and 53 of non-neoplastic lesions of the oral mucosa, which had been diagnosed using both cytology and histopathology specimens...

BACKGROUND: The Afirma gene expression classifier (GEC) is being increasingly utilized to confirm the benign nature of indeterminate FNA cytology results thus avoiding unnecessary surgical procedures. However the "suspicious" result of the Afirma GEC does not classify these indeterminate nodules further in determining appropriate management. This study investigated the outcome of the thyroid nodules deemed to be "suspicious" by the Afirma GEC in a high risk population. METHODS: The pathology database was searched for all thyroid nodules with Afirma test results over a three year period, 2013-2015...

BACKGROUND: Fine needle aspiration of pancreatic cystic lesions has its limitations as the cytology is often paucicellular to acellular. This study reports on the value of ancillary tests, amylase and carcinoembryonic, in the evaluation and management of patients with negative and non-diagnostic pancreatic cysts. METHODS: From January 1, 2010 through December 31, 2015, the Cytopathology Laboratory processed 119 pancreatic cyst aspirates of which 51(43%) were negative and 52(44%) were non-diagnostic and form the basis of this study...

Granulocyte colony-stimulating factor (G-CSF)-producing pancreatic tumors are extremely rare. These tumors have an aggressive clinical course and no established treatment. Here, we report an autopsy case of G-CSF-production in pancreatic anaplastic carcinoma (PAC). A 72-year-old woman presented with a large pancreatic head mass and multiple liver metastases. Laboratory data showed leukocytosis (leukocyte count 113.3 × 10(3) /µL) and high serum G-CSF levels (441 pg/mL; normal range: <39.0 pg/mL). The ascitic fluid was submitted to our pathology laboratory at initial diagnosis...

Xp11 translocation renal cell carcinoma (RCC) is a specific type of renal cell carcinoma recently placed under the "MiT family translocation RCC" at the last 2013 ISUP Vancouver classification of renal neoplasia. This tumor contains variable proportions of clear cells and could easily mimic papillary RCC, clear cell type, and clear cell papillary RCC. Given the small number of published cytologic findings of this tumor, it could easily present as a diagnostic pitfall. We describe a case of a 23-year-old man with a history of prior nephrectomy who presented with multiple mediastinal lymphadenopathies on imaging surveillance follow-up...

BACKGROUND: We aimed to analyze the significance of parakeratosis on an otherwise negative Papanicalaou (Pap) smear, in the absence of any characteristic human papilloma virus (HPV) findings. METHODS: A total of 22,076 Papanicalaou smears that were diagnosed as negative for intraepithelial lesions or malignancy between 2013 and 2015 were included in this study. Samples were separated into two groups, according to the presence of parakeratosis. We investigated the association between parakeratosis in the cytology results and a high-risk HPV status and high-grade squamous intraepithelial lesion (HSIL) in the colposcopic biopsy specimens...

Atypical polypoid adenomyoma (APA) is a rare mixed epithelial and mesenchymal tumor characterized histopathologically by the presence of disorganized hyperplastic glands with cytological atypia embedded in intersecting fascicles of fibromuscular stromal cells. Herein, we report the first documented endometrial cytological case of APA. A 35-year-old Japanese female presented with irregular menstrual cycles and then was found to have polypoid lesions of the endometrium. Cytological examination of the endometrium and endometrial curettage were performed...

The detection of primary anorectal melanoma on anal cytology is a rare and challenging diagnosis. We report a case where anorectal cytology showed isolated malignant cells with oval nuclei, prominent nucleoli, and elongated wispy cytoplasmic projections. There was no evidence of squamous dysplasia or melanin pigment identified. To the best of our knowledge, this is the first reported case of a primary anorectal melanoma detected in anorectal cytology. Detection of malignancies other than squamous cell carcinoma can be seen on anorectal cytology and should be considered when there is no evidence of anal intraepithelial neoplasia...

INTRODUCTION: Although cytology and histopathology of thyroid lesions generally fall into common, well-defined categories, there are uncommon cases with unusual fine needle aspiration (FNA) findings or histology. Herein, we review the prevalence and characteristics of rare thyroid cytology and histopathology findings at a tertiary hospital. METHODS: Institutional data from >31,000 patients with a thyroid pathology from 1995 to 2013 were queried. Both cytology and histology were available in 6,693 patients...

Blastoid variant (BV) is one of the aggressive variants of mantle cell lymphoma (MCL). BV-MCL is defined by its blastic cytomorphology. Previous studies using sequential biopsies in cases with MCL have demonstrated that classical type MCL (C-MCL) often transforms or relapses as an aggressive variant, but a histopathological transition from C-MCL to an aggressive MCL variant in the same pathological specimen has been shown in only a limited number of the cases. We present a case of MCL in which a histological transition between C-MCL and BV-MCL was observed in the same lymph node...

Endometriosis commonly involves the pelvis, but may also present as a palpable mass in extrapelvic sites, such as the abdominal wall or inguinal region, where it can be evaluated by fine needle aspiration (FNA). In this report, we illustrate the findings seen in seven cases of endometriosis diagnosed by FNA in patients with a chief complaint of pain associated with an abdominal wall or pelvic mass, occurring in a setting of prior pelvic surgery. The most common previous surgery was Cesarean section (n = 6), followed by hysterectomy (n = 2), and hernia repair (n = 1)...

BACKGROUND: Few studies have evaluated the cytology of pericardial effusions. The aim of this study is to investigate the etiologies of pericardial effusions and to establish the relationship between cytopathologic interpretations and outcome patterns among patients with pericardial effusions. METHODS: We identified 116 patients with pericardial effusions at a single institution over a 4-year period and carefully analyzed all available clinical documents, including clinical diagnoses, cytopathologic findings, and outcome patterns...

Anaplastic large cell lymphoma is an aggressive T-cell neoplasm. It rarely involves the urinary bladder, with just twelve cases reported thus far and only one being ALK-negative. Immunophenotyping (particularly for ALK) is mandatory, both for prognostic and therapeutic reasons. Herein, we report the case of a patient with an ALK-negative anaplastic large cell lymphoma involving the bladder which was diagnosed and fully characterized by immunocytochemistry in urine cytology. The patient underwent a cystoscopy and the urine sample disclosed tumor diathesis background and aggregates of atypical cells, with evidence of multinucleation and mitotic figures...
