Fine-Needle Aspiration Cytology of Epithelioid Leiomyoblastoma
نویسندگان
چکیده
Purpose. Epithelioid leiomyoblastomas comprise the majority of gastric sarcomas and are uncommon in other parts of the gastrointestinal tract. Diagnosis of this lesion by fine-needle aspiration cytology has been occasionally described in the literature. Two additional cases are herein reported.Subjects . A 66-year old male with an omental mass and a 47-year old male with a perihepatic tumor.Results and Discussion. Cytologic materials in both cases showed predominantly round or epithelioid cells, along with polygonal to spindle cells, occuring singly and in clusters, with oval to spindle-shaped nuclei.The nuclei were monotonous, usually banal, and centrally-located with only focal suggestion of pleomorphism and rare mitosis. Eosinophilic cytoplasm was noted in most of the cells, some demonstrating vacuolation. Electron microscopy supported a primitive smooth cell derivation of the neoplastic cells.Conclusions. The cytomorphology of the tumors of the two cases reported here is not adequately known. More cases need to be collected and studied.

Background and Objectives: Thyroid gland because of its superficial location is amenable to direct physical examination. Clinical assessment of thyroid lesions by means of physical examination, thyroid scans and ultrasonography is not completely reliable. Fine needle aspiration cytology (FNAC) is the most cost-effective, safe and an initial diagnostic test in the pre-operative evaluation of thy...
متن کاملDiagnostic pitfalls of pilomatricoma on fine needle aspiration cytology
Pilomatricoma is a benign skin adnexal tumour usually seen in the head and neck region of children and young adults. It is underrecognized on cytology, resulting in the overdiagnosis of malignancy. We bring forth a case report of a slow growing nodular swelling in a 10-year-old female child, which was misdiagnosed on Fine Needle Aspiration Cytology (FNAC) as a malignant neoplasm and found to be...

We describe the cytologic features in 2 cases of primary epithelioid sarcoma with samples obtained by fine needle aspiration (FNA). CASES Case 1 was a 50-year-old male who complained of a small mass in his left palm. Case 2 was a 56-year-old female who presented wi...
