Solitary Osteochondroma of the Third Toe Causing Claw Deformity: A Rare Presentation

Abstract

Osteochondroma is a benign osteocartilaginous lesion that commonly develops in the metaphyseal region of growing bones. Although it is the most prevalent benign tumor of the skeleton, its occurrence in the foot is uncommon, and involvement of the toe phalanges is rarely encountered. We present the case of a 16-year-old male who developed a progressively enlarging bony swelling over the third toe of the right foot, resulting in claw toe deformity and difficulty with footwear. Clinical and radiological assessment identified a pedunculated lesion originating from the proximal phalanx. Surgical excision of the mass, combined with correction of the associated deformity, was performed successfully. Histopathological examination confirmed the diagnosis of osteochondroma. The patient achieved good functional recovery with no evidence of recurrence during follow-up. This report draws attention to an unusual presentation of osteochondroma and emphasizes the importance of considering osseous lesions in the evaluation of acquired toe deformities.
