Abstract: Solitary bone lesions involving the lesser digits are a rare entity. Without pain but significant deformity the rightdiagnosis can be challenging. A 14 years old boy was admitted with a painless enlargement and clubbing involving the distal phalanx of the right great toe. X-rays were normal, only computer tomography and MRI showed a small round structure in the distal phalanx. Because of progression and unknown dignity a surgical excision was performed. Histologic examination of the painless lesion found an osteoid osteoma. No malignant change or recurrence appeared and the patient remained free of symptoms 2 years after operation.
