Giant cell tumor along with secondary aneurysmal bone cyst of scapula: A rare presentation.

Giant cell tumor (GCT) is a distinctive lesion characterized by the proliferation of multinucleate giant cells in a stroma of mononuclear cells; it is generally seen in skeletally mature individuals. GCT of bone is usually found in the long bones around the knee or in the distal radius of young adults and is unusual in the flat bones. We report a case of GCT of the acromion of the scapula, with a secondary aneurysmal bone cyst, in a 30-year-old female. Based on our review of the English language medical literature, it appears that the occurrence of a GCT along with a secondary aneurysmal bone cyst in flat bones (e.g.. the scapula) is very rare.
