Osteoid Osteoma of Proximal Phalanx of the Index Finger of the Right Hand

Osteoid osteoma is a benign bone forming tumor of the growing skeleton that is most often seen in young men. It represents by pain and radiologic appearance of anidus surrounded by osteosclerosisthat occurs mostly in long bones of the lower extremity. Occurrence of this tumor in the hand is an uncommon condition. We present a 23-year-old man with an osteoid osteoma in the proximal phalanx of the right index finger. The radiological examination showed a lytic lesion with irregular border with a central sclerotic nidus and also sclerotic changes around the lytic lesion and bone expansion in the proximal phalanx of the right index finger. He was suffering from a history of pain and swelling of his finger since 8 months. The pain disappeared after surgical excision of nidus. The patient was pain-free and there was no evidence of recurrence at 15 months follow up.
