title: "Nora lesion" - Bizarre parosteal osteochondromatous proliferation.
abstract: Nora lesion is a rare benign parosteal osteochondromatous proliferation involving feet and hand. Aggressive features on imaging and confusing results on histopathological studies make its diagnosis difficult. Since the time of its discovery, only few cases have been reported in the literature. Authors report a case of Nora's lesion on the planto-medial aspect of metatarsal head of great toe of left foot. The diagnosis was suspected by imaging characteristic features and was confirmed by histopathology. Treatment was surgical, with complete excision. There are no clinical or radiological signs of recurrence on further review 1 year post-operatively.
