To evaluate the histologic alterations due to the fine-needle aspiration (FNA), a comparative study between 20 aspirated and 20 nonaspirated thyroidectomy specimens was performed. The most common findings in the aspirated group were hemorrhage (80%) and vascular proliferation and/or vascular thrombosis (45%). In one of the aspirated cases with the cytologic(More)
We describe 3 cases of Hodgkin's disease (HD) of unusual suppurative type, which were diagnosed on fine-needle aspirates. The smears were dominated by neutrophils, macrophages, and cellular debris. Only a few large, atypical cells of Hodgkin and Reed-Sternberg type were observed. The differential diagnoses of such smears include infectious mononucleosis,(More)
UNLABELLED Sixty-three lymph node aspirates were screened and 32 aspirates revealing granulomatous lymphadenitis with or without caseation necrosis were re-evaluated. The most characteristic morphological features among these cases were epithelioid cell clusters with or without caseation necrosis. When clusters were thick, careful observation of the(More)
Adenoma is the most frequent type of gallbladder (GB) neoplasm; however, GB neoplasms are unusual and unsuspected diagnoses in childhood. The average patient age is 50.5±16.3 years. We present a case of tubulopapillary adenoma of the gallbladder in a 3-year-old girl. She was admitted to the hospital with a 6-month history of abdominal pain and nausea and(More)
261 Abstract:The aim of this study was to determine PCNA (Proliferating Cell Nuclear Antigen) and Ki-67 expression of various soft tissue sarcomas (STS) immunohistochemically and to correlate with the histologic grade of these tumors. Retrospectively 185 cases of STS were re-examined. Of the 185 cases, 35 primary STS cases which were localized in the(More)
Salivary duct carcinoma (SDC) is an uncommon and highly aggressive neoplasm that reveals histopathologic features resembling infiltrating duct carcinoma of the breast and prostate. SDC arising on the basis of preexisting pleomorphic adenoma (PA) is very rare. This report describes the fine-needle aspiration (FNA) cytology of a case of SDC ex PA. FNA smears(More)
BACKGROUND Hepatoblastoma is the most common primary hepatic tumor in children. The literature contains few examples of fine needle aspiration (FNA) cytology of these tumors. CASES A 5-month-old and 4-month-old underwent ultrasonography-guided FNA for the preoperative investigation of hepatic masses. The smears were stained with May-Grünwald-Giemsa and(More)
New techniques are being searched for the evaluation of cellular morphology and population of ocular surface. Impression cytology is one of the most preferred techniques in ocular surface sampling in dry eye, keratitis, and conjunctivitis. We evaluated and compared the efficacy of impression and brush cytology in 63 patients. All of the samples collected by(More)
Fine-needle aspiration cytology (FNAC) is a diagnostic tool used in the clinical workup of solitary thyroid nodules; however, differential cytologic diagnosis of these nodules often is challenging. With the goal of identifying cytologic findings that could improve predictions regarding the presence of neoplastic lesions, the authors performed a(More)
