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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
