Osteochondroma With Odd Clinical and Radiological Presentation

Osteochondroma is a cartilage-capped bony projection arising on the external surface of the bone, containing a marrow cavity continuous with that of the underlying bone. This benign tumor develops within the metaphysis of long bones. The growth is directed away from the growing end of long bones. We report a case of osteochondroma, also known as exostosis in a nine-year-old male child at the medial aspect of the right leg proximally. Marginal excision of the tumor was performed and sent for histopathological examination. The growth involved physis and epiphysis besides metaphysis and was directed toward the growing end of the tibia.
