[Angiolipoma of the kidney as a secondary tumor in a patient with a soft tissue sarcoma of the upper arm].

The case of a 51-year-old male presenting with a tumour of the left kidney is reviewed. In respect of an operated tissue sarcoma of the right humerus 6 months ago, radiological findings suggested a benign lesion, but could not exclude a metastasis of the sarcoma. Histological diagnosis revealed an angiomyolipoma of the kidney.
