A case of renal angiomyolipomas associated with multiple and various hamartomatous microlesions.
A case of 50-year-old woman who demonstrated large intrarenal and externally protruding angiomyolipomas (AMLomas), unusual intraglomerular lesions and multiple hamartomatous microlesions of various types within the kidney is reported. This type of intraglomerular lesion has been briefly described only twice previously in patients with tuberous sclerosis (TS), and is unique in its location and histological appearance. The lesions are mainly composed of proliferating mesangial cells and are hamartomatous in nature. Although no stigmata of TS other than renal AMLomas are apparent in this case, the presence of many renal hamartomatous lesions suggests the possibility of a forme fruste of TS.
