Turret exostosis of proximal phalanx of thumb

The osteochondromatous lesion of the skeleton is common occurrences and may have many variants, the knowledge of which is crucial for identification and treatment. Acquired osteochondroma, also known as Turret exostosis is one such lesion. The clinico-radiological picture often mimics that of a solitary osteocartilagenous exostosis, but the history of minor trauma as triggering event and histopathological correlation concludes the ubiquitous diagnosis. We present a case of Turret exostosis of thumb proximal phalanx on medial aspect with appropriate management.
