INTRODUCTION: The increasing use of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) cytology to examine pancreatic neoplasms has led to an increase in the diagnosis of metastases to the pancreas. Renal cell carcinoma (RCC) is the most common metastasis to the pancreas. Our study examines 33 cases of metastatic RCC to the pancreas sampled by EUS-FNA from four large tertiary care hospitals. MATERIALS AND METHODS: We searched the cytopathology database for RCC metastatic to the pancreas diagnosed by EUS-FNA from January 2005 to January 2015...

Poorly differentiated thyroid carcinoma (PDTC) is a very rare entity, and the diagnosis can be made on histopathology specimens. However, recognition of characteristic features of PDTC is significant on fine-needle aspirations (FNAs) to differentiate this entity from well-differentiated and anaplastic thyroid carcinomas. Here, we present an FNA case concordant with "oncocytic variant of PDTC" and discuss whether definitive diagnosis can be given on FNAs to assess the prognosis in clinically inoperable patients...

BACKGROUND: Papanicolaou Society of Cytopathology guidelines place low- and intermediate-grade pancreatic endocrine tumors into the "neoplastic, other" category whereas high-grade pancreatic endocrine tumors are placed in the "malignant" category. No attempt was made to stratify pancreatic endocrine tumors in the "neoplastic, other" category by likelihood for metastases. Histologically, pancreatic endocrine tumors are divided into well, intermediate, and poorly differentiated examples based on mitotic count and Ki-67 proliferation index (PI)...

When confronted with a metastatic poorly differentiated tumor of unknown origin, the initial workup includes the standard panel of immunostains to rule out carcinoma, sarcoma, lymphoma, and the greatest mimicker in pathology - malignant melanoma. Although not specific, the S-100 protein is expressed in over 95% of malignant melanomas. Herein, we present a case of multiorgan metastatic malignancy with a dominant hilar and mediastinal mass in a current smoker; clinically, highly suggestive of widespread primary lung cancer...

BACKGROUND: The stroma in fine-needle aspiration biopsy (FNAB) of thyroid lesions has not been well investigated. DESIGN: We studied 256 consecutive cases of thyroid FNAB prepared with traditional smear technique. The stroma was categorized: Type 1a consisted of long (more than 3 mm), broad bands composed of mesh containing collagen fibrils thickened by entrapped blood components and follicular cells. Type 1b consisted of dense strands/bands. Type 2 was similar to Type 1a but with shorter (<2 mm) and looser stromal strands...

In recent times, the diagnosis of breast lesions has mostly become dependent on core needle biopsies (CNBs) with a gradual reduction in the rate of performing fine-needle aspiration cytology (FNAC). Both the procedures have their pros and cons and outsmart each other taking into account different parameters. Both the methods are found to be fraught with loopholes, taking into account different performance indices, diagnostic accuracy and concordance, patient benefit, and cost-effectiveness. Unlike the popular belief of an absolute superiority of CNB over FNAC, the literature review does not reveal a very distinct demarcation in many aspects...

BACKGROUND: To evaluate and compare the role of Ziehl-Neelsen (ZN) staining and mycobacterial culture in diagnosis of tuberculous lymphadenitis. MATERIALS AND METHODS: A total of 56 fine needle aspirations (FNAs) from patients who were clinically suspected to have tuberculous lymphadenitis were included. Acid-fast Bacilli detection was attempted by ZN staining on smears as well as culture on Middlebrook 7H9 broth. Percentage positivity of both smears and culture was calculated...

Serous borderline tumor (SBT) involving a cervical lymph node is extremely rare. In addition, fine needle aspiration (FNA) cytology of the involved cervical lymph node shares tremendous morphologic similarity with other low-grade papillary carcinomas. Thus, it can be easily misdiagnosed as metastatic carcinoma. A 42-year-old female had a history of bilateral SBT and postbilateral salpingo-oophorectomy. She presented with left cervical lymphadenopathy 6 months later. FNA cytology showed a low-grade papillary neoplasm with psammoma bodies...

BACKGROUND: Developed countries adopted liquid-based cytology (LBC) cervical cytology, partly because of its lower proportions of unsatisfactory (U/S)/inadequate samples. This study was carried out to evaluate effect on the rate of U/S samples after introduction of LBC in our laboratory. MATERIALS AND METHODS: An audit of U/S cervical samples was performed, which included split samples (n = 1000), only conventional Pap smear (CPS) smears (n = 1000), and only LBC samples (n = 1000)...

Myoepithelial carcinoma (MECA) is one of the rarest salivary gland neoplasms, which may either arise de novo or develop within a preexisting pleomorphic adenoma or benign myoepithelioma. The tumor occurs mainly in the parotid gland followed by minor salivary glands and other body sites. As a result of their morphologic heterogeneity, they can be confused easily with many tumors. Awareness of their unique cytoarchitectural patterns and immunohistochemical profile is crucial for accurate identification. Herein, we report a rare case of a 51-year-old female patient with MECA of the maxillary sinus that metastasized to the pleural fluid...

Papillary cystadenocarcinoma is a very rare slow growing malignant neoplasm characterized by cysts and intraluminal papillary projections. It is defined by WHO as a separate entity. On FNA, cytological features can mimic with various papillary and cystic neoplasms of salivary gland. It is also difficult to distinguish from benign salivary gland neoplasms as it has bland nuclear features. Thus we present cytomorphological features and discuss its differential diagnosis with neoplasms having prominent papillary architecture with review of literature...

AIMS: To assess the adequacy of intraoperative scrape cytology during percutaneous vertebroplasty by correlating results with corresponding histopathology. SETTINGS AND DESIGN: Vertebroplasty is a procedure increasingly used to treat painful vertebral compression fractures. The history and presentation of osteoporotic fractures are straightforward, but difficulty arises in differentiating infective from neoplastic lesions, especially in cases where the magnetic resonance imaging is equivocal...

BACKGROUND: Female genital schistosomiasis (FGS) is a tissue reaction to lodged ova of Schistosoma haematobium in the genital mucosa. Lesions can make the mucosa friable and prone to bleeding and discharge. Women with FGS may have an increased risk of HIV acquisition, and FGS may act as a cofactor in the development of cervical cancer. OBJECTIVES: To explore cytology as a method for diagnosing FGS and to discuss the diagnostic challenges in low-resource rural areas...

Sclerosing hemangioma of the lung is a benign neoplasm with a widely debated histogenesis. It has a polymorphic histomorphology characterized by a biphasic cell population of "surface cells" and "round cells" arranged in four general patterns: Papillary, solid, angiomatous, and sclerotic. This variability in histomorphology makes it difficult to diagnose sclerosing hemangioma by fine needle aspiration (FNA). We present a case of sclerosing hemangioma diagnosed on FNA with immunohistochemistry performed on an accompanied cell block...

The cytomorphologic features of clear cell neuroendocrine tumor of pancreas have been rarely reported in cytology literature. The cytomorphology of this rare variant mimics many primary and metastatic clear cell tumors of the pancreas. However, a precise cytological diagnosis can be rendered by awareness of this entity and judicious use of immunohistochemistry. We report one such case in a young woman diagnosed on endoscopic ultrasound fine needle aspiration. The tumor cells showed positive staining with synaptophysin, chromogranin, and also with inhibin...

BACKGROUND: Iron overload is a medical condition that occurs when too much of the mineral iron builds up inside the body and produces a toxic reaction. Thalassemia is a genetic disorder of hemoglobin synthesis, which requires regular blood transfusion therapy, and the lack of specific excretory pathways for iron in humans leads to iron overload in the body tissues. It is a major cause of morbidity and mortality in these patients. The estimation of iron levels in exfoliated buccal mucosal cells may provide a simple, noninvasive, and a safe procedure for estimating the iron overload by using the Perls' Prussian blue stain...
