Solitary osteoclast-like giant cell tumor of the kidney: a case report

Abstract

Osteoclast-like giant cell tumors are very uncommon and originate in osseous and tendinous tissues. However, they are also very rarely found in visceral organs. The kidney is extremely rarely affected by this tumor entity; usually osteoclast-like giant cell tumors are associated with papillary renal cell carcinoma. We present the third case in the literature of a solitary osteoclast-like giant cell tumor in the kidney of an 89-year-old man and give a short overview of the current literature.
