Hallux Osteoid Osteoma: A Case Report and Literature Review

Osteoid osteoma is a benign bone tumour that mostly affects males in the second and third decade of their life. The lesion mainly occurs in long bones, usually in the femur and tibia, causing severe localized pain that is worse at night and responds to nonsteroidal anti-inflammatory drugs (NSAIDs). Diagnosis is usually made on the basis of history and radiographic findings. However, in more unusual locations as the hand and foot, diagnostic issues can arise. Treatment often includes complete removal of the tumor. We present a 22 year old male with osteoid osteoma involving the distal phalanx of the hallux. To our knowledge very few cases of great toe osteoid osteoma have been reported in the literature.
