Abstract: Parosteal osteochondromatous proliferation also called Nora’s lesion is a rare tumor which occurs on the proximal/distal phalanx, metacarpals, metatarsals of hand (more commonly) and feet. These lesions show 50% recurrence following excision. It has atypical histo-pathological features that must be differentiated from chondrosarcoma, low grade parosteal osteosarcoma and conventional osteosarcoma. Among benign lesions florid reactive periostitis, myositis ossificans, periosteal chondroma and osteochondroma should be considered.
