Intermetatarsal osteochondroma in a pediatric patient: a rare case of chronic foot pain and surgical resolution

Osteochondroma involving the metatarsals is extremely rare, often presenting diagnostic and clinical challenges due to its atypical anatomical location and potential biomechanical complications. The patient, a 10-year-old boy, presented with a 2-year history of dorsal foot pain exacerbated by walking, which was unresponsive to immobilization and analgesia. Radiographic findings revealed a bony mass extending from the medial cuneiform to the first metatarsal, causing a widening between the first and second metatarsals. Given the significant effect on daily activities and persistent pain, surgical excision was performed. Intraoperatively, the lesion was consistent with osteochondroma, and complete resection was performed. His recovery was uneventful, with symptom resolution and improved functional outcomes at routine follow-up. Osteochondromas can cause pain, deformity, and restricted movement when located in weight-bearing areas. In intermetatarsal osteochondroma, surgical excision is warranted for symptomatic relief and functional improvement.
