Recurrent osteoid osteoma of the lunate: a case report and review of the literature.

Osteoid osteoma is a benign tumour of bone that rarely localises in the carpal bones. Its treatment by curettage and bone grafting is considered to be curative and its recurrence is thought to be rare. We report a case of an osteoid osteoma of the lunate, which recurred seven years after the initial operation. Recurrent osteoid osteoma of the lunate bone has not been reported in the literature. We present this case report for its atypical presentation and diagnostic difficulty and also to alert the readers of the possibility of an osteoid osteoma as a cause of the chronic unexplained wrist pain in young adults.
