Case description (by case creator):

Renal angiomyolipoma with epithelial cyst (AMLEC). The spindle cells surrounding the central cyst are positive for HMB45 and Melan A. The lesion also contains scattered, thick-walled blood vessels and microscopic areas of admixed fat. The central cyst is lined by a single layer of bland cuboidal/hobnail epithelial cells.
