We report the a case of Nora's lesion (Bizarre Parosteal Osteochondromatous Proliferation) of the sesamoid. A 32-year-old woman presented with a painless, enlarging mass of two years duration on the plantar aspect of the first metatarsophalangeal joint of the left foot. Radiographs, Computerized Tomographs and Magnetic Resonance images, initially suggested a parosteal osteosarcoma arising from the tibial sesamoid. The mass was excised, and a histological diagnosis of Bizarre Parosteal Osteochondromatous Proliferation of bone (Nora's lesion) was made. The aggressive growth of this lesion may suggest a neoplasm clinically. Histological features, however, are those of a reactive lesion.

Isolated primary bony lesions of the digits are infrequent. A phalangeal lesion in the hand is most likely to be benign. Rarely, however, primary benign tumour-like conditions affecting the handmay radiologically mimic an osteochondroma and histologically mimic a malignancy. We describe a case of bizarre parosteal osteochondromatous proliferation (Nora’s lesion, BPOP), which may do both and mislead the unsuspecting surgeon. The aim of this paper is to present our experience with this case, review existing literature and promote awareness among hand surgeons of a condition that can often be misdiagnosed.
