hyalinizying clear cell carcinoma is a rare tumor which affects women more than men and is more common in minor salivary glands. the purpose of this paper was to describe a case of hyalinizing clear cell carcinoma of buccal vestibule in a 55-year-old woman. it is important to differentiate this neoplasm from other tumors with clear cell features because of their differences in treatment and cli...

Introduction. Clear cell basal cell carcinoma (BCC) is an uncommon and unusual variant of BCC, which is characterized by a variable component of clear cells. The pathogenesis of this histological variant and its clinical significance has not been clarified. Differentiation of this uncommon variant of BCC from other clear cell tumors is important for the treatment. Case Presentation. A 65-year-o...

primary clear cell adenocarcinomas most commonly involve the genitourinary system, including the vagina. previously, primary clear cell adenocarcinomas of the vagina have been discussed within the context of prenatal exposure to diethylstilbestrol. due to its widely proven role in the development of this carcinoma, administration of diethylstilbestrol is prohibited. we present two cases of non-...

Malignant transformation of endometriosis is an infrequent complication. Clear cell carcinoma from endometriosis is very rare in the paraovarian cyst. To date no cases have been reported. We report a case of clear cell carcinoma arising from endometriosis of the paraovarian cyst with a brief review of literature.

A case is reported with clear cell sarcoma (CCS) of the hand. Early diagnosis of clear cell sarcoma is always difficult due to its slow growing nature, benign clinical appearance, lack of pigmentation in most cases, and relatively young age of patients which make it to clinically appear as a benign soft tissue tumor. We report a case of clear cell sarcoma of hand in a 56 year old male with a no...

Introduction: Metastatic lesions of the oral cavity are extremely rare, accounting for approximately 1% of all malignant oral tumors. The most common primary sources of metastatic tumors in the oral region are, from the most to the least common, the breast, lung, kidney, bone, and colon. Renal cell carcinoma accounts for nearly 3% of all adult malignancies. It usually metastasizes to the lungs,...

OBJECTIVE The aim of this study was to estimate the survival impact of lymphadenectomy in patients diagnosed with uterine clear cell cancer (UCCC). METHODS Patients with a diagnosis of UCCC were identified from Surveillance, Epidemiology, and End Results (SEER) program from 1988 to 2007. Only surgically treated patients were included. Statistical analysis using Student t-test, Kaplan-Meier su...
