Osteochondroma With Odd Clinical and Radiological Presentation

TL;DR

This paper presents a rare case of osteochondroma in a child where the tumor grew toward the growing end of the tibia, which is unusual for this type of benign bone tumor.

Contribution

The paper reports a unique clinical and radiological presentation of osteochondroma involving the physis and epiphysis and growing toward the growth plate.

Findings

The tumor was located on the medial aspect of the right tibia in a nine-year-old male.

Histopathological examination confirmed the diagnosis of osteochondroma.

The tumor's growth direction was toward the growth end of the tibia, which is atypical.

Abstract

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.
