Bizarre parosteal osteochondromatous proliferation (BPOP), as defined by Nora and colleagues in 1983 (also called Nora lesion), is a rare lesion. About 160 cases of BPOP have been presented in the literature to date. The lesion is an exophytic outgrowth from the cortical surface consisting of bone, cartilage and fibrous tissue. These types of lesions have been reported mostly in the hands and feet. Localization at the level of the skull is extremely rare. We report a case of a young man with multiple Nora’s lesions with atypical localization in the skull and mandible.
