Bizarre Parosteal Osteochondromatous Proliferation
Chapter
Abstract
Osteofibrocartilaginous benign process arising in the surface of a bone, more common in hand and foot locations. There is no sex predominance and it is more common in the second and third decades. Near 75 % of cases are located on the surfaces of small bones of the hands and feet, more commonly in the proximal phalanges. Radiologically it is a he terotopic well-marginated calcified rounded mass attached to the cortical surface of the bone. The lesion presents three components: cartilage, bone, and spindle cells. Treatment consists of excision. Recurrence is seen in half of the patients. Malignant transformation is not reported.
