OBJECTIVES: Endoscopic ultrasound-guided fine-needle aspiration (FNA) is now widely used as a primary tool to diagnose pancreatic neoplasms. However, criteria that can reduce the risk of overdiagnosing pancreatic adenocarcinoma by FNA have not been adequately defined in the literature. This study aims to identify characteristic cytomorphological features that are helpful in distinguishing pancreatic adenocarcinoma from its mimics. STUDY DESIGN: Five false-positive FNA cases (group A) diagnosed as adenocarcinoma (4 cases) and suspicious for adenocarcinoma (1 case) by FNA, were identified by searching our laboratory information system...

OBJECTIVES: Pancreatic serous cystadenomas (SCAs) are benign tumors. Technological advances in imaging have led to increased recognition of asymptomatic pancreatic cysts, consequently increasing the demand for cytomorphologic evaluations of cyst fluid. STUDY DESIGN: A retrospective search through the pathology archives over an 11-year period was performed to identify SCAs from pancreatectomy specimens with a presurgical pancreatic EUS-guided fine-needle aspiration (FNA)...

BACKGROUND: Cytomorphology of exfoliated atypical reactive/repair renal tubular cells (RRTC) can resemble atypical urothelial cells thus suggesting a differential diagnostic question of urothelial neoplasia in urinary cytology. Vimentin expression has been shown in RRTC and used for differentiation from atypical urothelial cells. METHODS: The institutional computer database was searched for urinary cytology cases with vimentin immunocytochemical staining (2008-2012)...

Twelve lung neuroendocrine tumors with morphologic features of carcinoid tumors but with mitotic count >10/2 mm are reported. There were 7 males and 5 females, with age ranging from 56 to 78 years. Four cases were from never-smokers. All tumors showed architectural and cytomorphologic features of carcinoid tumor, including organoid nesting, insular, trabecular, or acinar growth, and tumor cells with low nucleocytoplasmic ratio, abundant cytoplasm, ovoid to round nuclei, and salt and pepper chromatin. Angulated or confluent nesting, insular or lobular growth pattern was also seen...

Tanycytic ependymoma is a rare variant of ependymoma which has a predilection for the spinal cord. It is a WHO grade II tumour with favourable outcome. Although squash cytology of ependymoma is well described, there is sparse literature available on squash cytomorphology of tanycytic variant. Here we present two cases of squash cytology of tanycytic ependymoma. In the first case the diagnosis of tanycytic ependymoma was considered. However, in the second case a diagnosis of usual ependymoma was offered. Subsequently histopathology confirmed tanycytic nature in both the cases...

BACKGROUND: Grade 2 nodular sclerosis classical Hodgkin lymphoma (NSCHL) is less common than grade 1 lymphoma and has a worse overall prognosis. To the best of the authors' knowledge, no study of a large series of cases has been performed until now. The objective of this study was to assess the diagnostic efficacy of cytology for grade 2 NSCHL versus grade 1 NSCHL and study the morphological features of grade 2 NSCHL in fine-needle aspiration cytology (FNAC). METHODS: Fifteen of 51 histopathology-proven cases of NSCHL (18 FNAC procedures) were grade 2, and 36 were grade 1...

In lung cancer patients, the only available diagnostic material often comes from biopsy or from cytological samples obtained by fine needle aspiration (FNA). There is a lack of easily detectable cytomorphological features for rapid on-site evaluation (ROSE) to orient lung cancer diagnosis towards a specific tumor histotype. We studied the cytological features evaluated on site to define tumor histotype and to establish the number of specimens to be taken. Cytological specimens from 273 consecutive patients were analyzed with ROSE: bronchoscopy with transbronchial needle aspiration (TBNA) had been performed in 72 patients and with endobronchial ultrasound (EBUS)-TBNA in 201...

We report the case of a 26 year-old patient presenting with a persistent leukocytosis and CML-like marrow but no evidence of a BCR/ABL1 fusion. Molecular cytogenetics revealed that a portion of the ETV6 locus was inserted into the ABL1 locus. An ETV6/ABL1 fusion transcript could subsequently be confirmed. The patient was started on imatinib and went into complete cytomorphological remission. QRT-PCR measurements showed a 4 log reduction of the ETV6/ABL1 fusion. 15 months later, the disease transformed into ALL and the patient expired...

Epithelial-Myoepithelial Carcinoma (EMC) is a rare low grade epithelial malignancy of major Salivary Glands (SG). Though the histomorphology of this tumor is distinct, unusual location and clinical presentation may pose diagnostic difficulties especially when this lesion is first encountered at cytology. We report a case of 60-year-old female presenting with nasal obstruction of three months duration. At FNAC the diagnosis of EMC was suggested and it was confirmed on histopathology. We present this case highlighting the cytomorphologic attributes of this rare tumor occurring at an extremely uncommon location - Nasal cavity...

Recent studies have identified translocations involving the kinase domains of ALK, NTRK1, BRAF, RET, and ROS in spitzoid neoplasms. Subsequent studies have also characterized morphologic features corresponding to ALK and NTRK1 translocations. In this study, we sought to further compare morphologic features across a range of 49 genetically defined spitzoid neoplasms with ALK, NTRK1, BRAF, or RET fusions to determine discriminating features. We also compared them with a group of 22 spitzoid neoplasms, which were confirmed to be negative for fusions in ALK, NTRK1, BRAF, and RET...

Here, we present the first cytological report of a primary splenic inflammatory pseudotumor-like follicular dendritic cell sarcoma. The 57 year-old male was incidentally found with a 2.2 cm well-demarcated splenic nodule. A sonography guided fine needle aspiration of the lesion was performed. The cytologic smears revealed loosely cohesive fragments of oval to spindle cells in a background of prominent lymphoplasmacytic infiltration. The cells showed sparse chromatin, distinct nucleoli, syncytial cell borders, and occasional cytoplasmic processes...

We describe a case of synovial sarcoma originating from prostate gland. The diagnosis was confirmed by fluorescent in situ hybridization analysis (FISH) for SYT rearrangement on the cell block. Synovial sarcoma is a high grade soft tissue malignancy with exceedingly rare involvement of genitourinary tract. However this entity should be considered in the differential diagnosis when dealing with aspiration biopsies of particularly deep seated lesions with spindle cell or small round blue cell cytomorphology. Diagn...
