This entity shares morphologic and immunohistochemical features with the secretory carcinoma (SC) of the breast. MASC usually presents as an asymptomatic mass in the parotid gland and predominantly affects men. This tumor is considered a low-grade carcinoma(More)
BACKGROUND Extraskeletal myxoid chondrosarcoma (EMC) accounts for the 3% of all soft tissue sarcomas and it's categorized as a tumour of uncertain differentiation. This entity has shown to have the recurrent balanced chromosomal translocation t(9;22) (q22;q12.2), which leads to the oncogenic fusion gene EWSR1-NR4A3. This sarcoma usually presents as a slow(More)
BACKGROUND Adrenal tumors that secrete androgens exclusively are extraordinarily rare. The aim of this study was to characterize patients with pure androgen-secreting adrenal tumors. METHODS A retrospective chart review from January 1946 through November 2002 identified 11 female patients with pure androgen-secreting adrenal tumors. RESULTS The mean age(More)
Aortitis identified in approximately 12% of all thoracoabdominal aneurysms. The most common subtype of inflammatory aortitis is giant cell aortitis, followed by lymphoplasmacytic aortitis. Inflammatory aortitis may occur in isolation or as part of a systemic inflammatory disorder such as Takayasu arteritis, systemic lupus erythematosus, rheumatoid(More)
