Osteochondroma in a Cat

Abstract

A Siamese female cat 2.5 years old weighing about 4 kg was submitted with lameness as chief complaints. Radiological examination revealed a relatively homogeneous shadow on the medial side of a proximal part of the right tibia. A tumor weighing 17g was removed surgically from this part. It was demonstrated to be osteochondroma showing a remarkable tumorigenic activity.
