Abstract:
In 1983, Nora et. al. reperted 35 cases of bizarre parosteal osteochodromatous proliferations of the hands and feet. All lesions occured on proximal phalanges, metatarsals, or metacarpals. The gross appearance was typically that of a small osteochondroma. Radiologically, the proliferations lacked both central continuity of the tumor with the underlying osseus medulla and flaring of the adjacent cortices. Histologically, the lesion exhibited marked proliferative activity, irregular bohy cartilaginous interface, and enlarged, bizarre, and binucleate chondrocyte. The authors experienced a case of bizarre parosteal osteochondromatous proliferation of the right foot in a 61 year-old female which arised from the proximal phalanges of second toe, hostologic and radiologic findings were consistent with the bizarre parosteal osteochondromatous proliferation. The mass was treated by excision, and neither recurrence, nor malignant change was observed up to one year follow-up period.
