Bizarre parosteal osteochondromatous proliferation in the fifth rib : report of a case with novel presentations

Bizarre parosteal osteochondromatous proliferation (BPOP) is a rare benign surface osteocartilaginous lesion, mainly affecting the small bones of the hands and feet. Here, we present a case of a young male with a mass in the lib that originally was thought to be a chondrosarcoma. After pathology consultation in our hospital, the final pathology diagnosis was BPOP, also called Nora’s lesion. The location of the lesion of the patient was atypical. To our knowledge, this was the first report of BPOP in the rib.
