Abstract
Nora’s tumor, also known as bizzarre parosteal osteochondromatous proliferation (POPB), is an exophytic outgrowth arising from the cortical surface of the bone that consists of a mixture of bone, cartilage and fibrous tissue. It is a benign lesion with atipical microscopic features and a tendency to recur. It must be distinguishable from parosteal osteogenic sarcoma, parosteal chondrosarcoma, osteochondroma, florid reactive periostitis, turret exostosis, subungueal exostosis, myositis ossificans. The treatment is surgical, but a high rate of local relapse is described. The diagnosis is histological. We report a case of a patient with POPB involving the foot, underwent surgical excision and with no evidence of recurrence at one year.
