A Case of Giant Cell Tumor of the Hipbone Invading the Bladder

Abstract

Giant cell tumor of bone (GCTB) is a very rare neoplasm of the skeleton (about one new case per million population per year). In literature there is a great confusion about GCTB. The majority of authors think that GCTB is a benign locally aggressive tumor, others think that this is a malignant neoplasm and some authors think that GCTB is a reactive condition. This is the first case in literature of GCTB of the hipbone invading the bladder.
