Ocular cytology specimens are relatively uncommon, adding to the difficulty of their evaluation by cytopathologists. While melanomas account for a majority of primary intraocular pigmented lesions, other diagnostic considerations must be included in the differential. This brief report highlights a case of a pigmented ocular lesion in a 24-year-old man and key morphologic, immunohistochemical, and clinical differences between melanoma, melanocytoma, choroidal nevus, and retinal pigment epithelium (RPE) adenoma...

INTRODUCTION: Although pathology services focused on fine needle aspiration (FNA) biopsy of superficial palpable masses with on-site cytological evaluation are available in a wide range of clinical and academic settings, the addition of ultrasound (US) guidance into FNA practice by a cytopathologist group can be challenging. An US-FNA service provided by a cytopathologist in the department of Pathology is a relatively new practice in the field of medicine. This report summarizes our experience and strategies in achieving this objective and our successful preliminary results...

Clear cell sarcoma-like tumor of the gastrointestinal tract (CCSLGT) is an extremely rare malignant neoplasm in the digestive tract. Its cytomorphologic features have never previously been reported. Here, we describe a case of CCSLGT, including its cytologic examination findings. A 47-year-old woman presented with a mass in the small intestine, which was resected and sent for imprint cytology. Imprint smears revealed tumor cells with light eosinophilic or clear cytoplasm in a necrotic background. Many of the tumor cells were arranged in a perivascular growth with a pseudopapillary formation, and there were some non-neoplastic osteoclast-like giant cells...

Dissemination of lymphomas in serous effusions is quite common. Cytology aims to contribute in the clinical management of haematologic patients, providing an accurate and rapid diagnosis. Ancillary techniques such as immunocytochemistry and flow cytometry are essential to classify the lymphoma entity. Comprehensive awareness of the clinical picture and previous histologic documentation are essential for a lymphomatous effusion diagnosis. We report an unusual case of monomorphic epitheliotropic intestinal T-cell lymphoma, formerly known as enteropathy associated T-cell lymphoma (EATL) type II, spreading in the pleural cavity...

INTRODUCTION: The use of fine-needle aspiration (FNA) cytology for the preoperative evaluation of salivary gland lesions is an accepted but, currently, nonstandardized practice. More specifically, cystic major salivary gland lesions are relatively rare and can be very challenging to diagnose on FNA due to low cellularity and an incredibly broad differential diagnosis. The purpose of this study was to investigate the diagnostic utility of preoperative FNA cytology for cystic major salivary gland lesions...

Vaginal carcinoma is a rare condition. In this report, we describe a case of a poorly differentiated aggressive adenocarcinoma in a woman with a three month history of vaginal bleeding and a negative Pap smear done six months prior to her consultation. Specular examination showed a normal cervix, but there was a bleeding ulcer (2 cm in diameter) in the upper third of the vagina. Cytology revealed poorly differentiated atypical cells, and the biopsy established a diagnosis of vaginal adenocarcinoma with little differentiation...

Urinary tract lymphoma is unusual, with the kidney being the most commonly reported site of involvement. Urinary bladder involvement by lymphoma is rare. Mantle cell lymphoma (MCL) is a relatively uncommon type of lymphoma. Herein, we report a case of MCL of the urinary bladder diagnosed by urine cytology, with confirmatory immunocytochemical stains, which has not previously been reported in the literature.

Fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) has an effective role in both diagnosis and management of patients with lung cancer. There are many reasons could cause false positivity on PET/CT.A 60-year-old man was admitted a mass on thorax CT and diagnosed as squamous cell carcinoma. Lobectomy with lymph node dissection was performed after evaluation of distant metastases. There were pathological lymph nodes detected on PET/CT at six month following period. Endobronchial ultrasonography guided transbronchial needle aspiration was performed for differantial diagnosis...

One case of intraductal carcinoma of the parotid gland in a 67-year-old male patient is here introduced. The patient, who had a one-year history of a parotid mass, had undergone ultrasound and MRI examination that disclosed a 13x4x3 mm well delimited nodular mass of the accessory lobe of his left parotid gland. Ultrasound-guided Fine Needle Aspiration (FNA) had been performed by the clinician. The obtained smears showed widespread cellular necrosis in which cellular clusters with moderate and focally severe atypias displayed papillary and cribriform architecture and were admixed with sheets of epithelial cells with less striking nuclear atypias, squamous, or apocrine metaplasia...

Phaeohyphomycosis is an unusual granulomatous fungal infection, observed in immunocompromised or diabetic patients; however, it is even rarer in immunocompetent patients. Cytological findings of the same have been infrequently reported. The histopathological diagnosis or fungal culture helps in definitive diagnosis to identify the exact fungal species. Hereby, we report a rare case of invasive fungal infection in a breast lump in a young female, presenting as fibroadenoma breast. Fine needle aspiration cytology from the breast lesion showed the presence of septate acute-angled branching fungal hyphae with focal pigmentation, morphologically suggestive of phaeohyphomycosis which was positive with fungal stains...

Metastatic carcinoma to the pancreas is uncommon and head and neck squamous carcinoma metastatic to the pancreas is extremely rare. Metastatic squamous cell carcinoma to the pancreas presents a unique diagnostic challenge: in addition to mimicking the rare primary squamous cell carcinoma of the pancreas based on cytologic, histologic, and immunohistochemical features, it may be mistaken for a cystic neoplasm of the pancreas because of its high predilection for cystic degeneration in metastatic sites. Herein, we report a case of tonsillar squamous cell carcinoma with a cystic pancreatic metastasis diagnosed by ultrasound-guided fine needle aspiration biopsy (EUS-FNA)...

Chondrosarcoma (CS) of larynx is a rare laryngeal tumor accounting about 1% of laryngeal malignancies. When CS arises from thyroid cartilage, it may clinically present as a thyroid nodule. Here we report a rare case of CS of thyroid cartilage misinterpreted as medullary thyroid carcinoma. The main aim of this case report is to emphasize the important role of accurate clinical history, appropriate physical examination, and proper localization of the tumor and clear definitive imaging in conjunction with interpretation of cytologic smears...

Herein, we present a rare case of intracranial extramedullary hematopoiesis (EMH) diagnosed by cerebrospinal fluid (CSF) cytology and describe the clinical presentation, radiologic, and pathologic findings. A 65 year-old man with a history of progressing primary myelofibrosis was admitted for headaches and right facial numbness. A brain MRI revealed focal abnormalities that were suspicious for leptomeningeal involvement of acute leukemia. Cytologic examination of CSF demonstrated a hypercellular specimen composed of hematopoietic cells including few blasts, as well as maturing red blood cells and granulocytic cells...

BACKGROUND: Metastatic tumors to the pancreas are rarely encountered and diagnostically challenging. We aspired to determine the incidence and origin of all metastases to the pancreas at our institution, and to examine their clinicopathologic and cytomorphologic features. We also sought to ascertain the effect of endoscopic ultrasound (EUS) guidance implementation. METHODS: A search of our database was undertaken to review all pancreatic FNA and/or CNB examined from January 2000 through December 2014...
