Bizarre parosteal osteochondromatous proliferation of the hands and feet

Abstract

Two adults with bizarre parosteal osteochondromatous proliferation of the hands and feet are presented. The preoperative diagnosis may be difficult to make and the correct diagnosis was not made in either case until pathological examination of recurrent tumour masses occurred. The radiological and pathological features of this lesion are discussed. The diagnostic features which differentiate this condition from other causes of new bone formation in the peripheries are described.
