Clear cell carcinoma of cervix in a postmenopausal woman: A case report.

Clear cell carcinoma of cervix is a very rare neoplasm accounting only 4% of all cervical adenocarcinomas. Intrauterine exposure to diethylstilbestrol (DES) is supposed to be causative factor for clear cell adenocarcinoma in childhood and young-age patients. We are reporting a case of clear cell carcinoma of cervix in a 49-years-old multiparous post-menopausal woman, who had no exposure to DES (in-utero) or synthetic non-steroidal estrogen.

Fine-needle aspiration cytology of chondroid syringoma of fore arm: Report of a rare case.

Chondroid syringoma is a rare benign adnexal tumor of sweat glands with microscopic resemblance to the salivary gland pleomorphic adenoma. Cytology is rarely utilized for preoperative assessment of these slow-growing, small, nodular lesions. Definitive cytological diagnosis is also quite difficult, and majority of the aspirates are evaluated as benign adnexal tumors leading to mandatory histopathological examination for pinpoint diagnosis. Here, we report a case of chondroid syringoma of forearm, which was diagnosed by cytology and also confirmed after histopathological examination. Pinpoint cytological diagnosis can help early formulation of necessary management protocol.

Fine-needle aspiration cytology of retroperitoneal lesions: a 5-year experience with an emphasis on cytohistological discrepancy.

BACKGROUND: The retroperitoneal space contains various organs which can be affected by various non-neoplastic and neoplastic pathological processes. A diagnosis of these retroperitoneal lesions is often difficult. Fine-needle aspiration cytology (FNAC) under image guidance is now becoming an effective tool for the initial evaluation of retroperitoneal lesions. OBJECTIVE: The present study was undertaken to evaluate the role of ultrasound-guided FNAC in the diagnosis of retroperitoneal lesions in comparison to histopathology and to assess the probable causes of failure in cases of pitfalls in cytodiagnosis. MATERIALS AND METHODS: During the study period of 5 years, a total of 104 cases of retroperitoneal lesions were aspirated under USG guidance. Seven cases yielded inadequate material, the remaining 97 cases were included in the study group. RESULTS: Out of 97 cases, the kidney was the most common organ aspirated (27 cases; 27.8%). Malignant lesions (68 cases; 70.1%) were much more frequent than benign or non-neoplastic lesions (29 cases; 29.9%). Tuberculosis was the most common non-malignant lesion (14 cases) and renal cell carcinoma was the most frequent malignant lesion encountered (15 cases). In 5 cases (7.9%), the histological diagnosis showed inconsistent results in comparison to cytodiagnosis. CONCLUSION: USG-guided FNAC is a safe, rapid, relatively cheap and fairly accurate procedure for the assessment of retroperitoneal lesions.

Malignant proliferating trichilemmal tumor.

Proliferating trichilemmal tumor (PTT) is a benign tumor originating from the outer root sheath of a hair follicle. Malignant transformation in case of PTT is very rare and unusual finding. It is usually confused with squamous cell carcinoma both sharing many common features. So the identification of malignant PTT is very essential. Only 39 well-documented cases of malignant proliferating trichilemmal cyst have been published to date in the English language literature. We hereby present a case of a 75-year-old female patient with a rapidly growing swelling on the scalp.
