Bilateral osteochondroma in a child: A rare case report

Abstract

Abstract Osteochondroma has an incidence of 1 in 50,000 and is the most common benign bone tumor, which accounts for 30% (range 20%–50%) of all benign bone tumors. The incidence of osteochondroma is higher in males than females in both its solitary and hereditary forms. Osteochondroma can arise from any bone that develops from enchondral ossification. It commonly involves the long bones, and it rarely involves the ribs. Lesion is common in childhood, with 75%–80% occurring before the age of 20. Here, we report a case of bilateral rib osteochondroma that was presented during infancy.
