Abstract

A 50 yr man presented with fatigue and fever. He was found to have a 7.2 cm left renal mass. Radical nephrectomy was done. The mass was HMB-45 negative renal angiomyolipoma. This patient did not have tuberous sclerosis. His fever resolved after the tumor excision. This case is unique because of the unusual morphology and histology of the tumor. It reiterates that getting rid of inflammatory cytokines being produced by the tumor will cause resolution of fever.
