Abstract

Osteochondromas develop as cartilaginous nodules in the periosteum of bones. They are the commonest benign tumors of the skeleton, generally observed in the long bones. Rarely, they are also found in the axial skeleton, flat bones of skull and facial bones. During a regular dissection, we came across a solitary osteochondroma in posterior surface of the body of the right pubic bone. Histopathology of the bony projection confirmed the typical features of the osteochondroma. The symptomatic osteochondromas are usually evaluated during radiographic examination. Though, the observed osteochondroma is relatively smaller its unusual location is remarkable and knowledge of occurrence of such nodules is clinically important during the diagnosis and planning of treatment.
