Mixed renal tumor with carcinomatous and fibroleiomyomatous components, associated with angiomyolipoma in the same kidney.
A 54-year-old woman, without the stigmas of tuberous sclerosis, underwent radical nephrectomy for simultaneous occurrence of an Angiomyolipoma (AML) and a carcinomatous and fibroleiomyomatous mixed tumor in the same kidney, diagnosed by computerized tomography, selective renal arteriography and anatomopathological examination. The peculiar findings of the mixed neoplasia, characterized by a mixture of carcinomatous and fibroleiomuscular components are stressed. The latter component is considered to be a proliferative element interacting with the carcinomatous one. After review of the pertinent literature, this is the first example of an association of AML and renal cell carcinoma (RCC) in which the RCC is constituted by a mixture of carcinomatous and fibroleiomyomatous cells.
