Osteoid osteoma is a benign tumor originating from osteoblasts, and it is mostly seen in long bones of lower limbs. The distal phalanx of the foot is an atypical location for an osteoid osteoma, and lesions occurring in this location may be a diagnostic challenge. A 22-year-old man presented with a complaint of severe pain on the second distal phalanx of his right foot. An osteoid osteoma was suspected after radiologic evaluation. The lesion was surgically excised and removed completely by curettage. Histopathologic evaluation confirmed the diagnosis of an osteoid osteoma. The patient was followed-up for a 9-month period without any symptoms or recurrence.
