[Post-traumatic osteoid osteoma of the hand. A rare cause of chronic pain. Case report and review of the literature].

One year after a nonspecific trauma and with a history of pain of four weeks only, an osteoid osteoma of the first phalanx of the left thumb was diagnosed in a 31-year-old man. The radiologic appearance as well as a bone scan were suggestive for an osteoid osteoma. The diagnosis was confirmed histologically after resection of the tumor. As indicated in the literature, osteoid osteoma of the hand is relatively rare. The symptoms and radiologic features (osteolytic nidus and sclerosis) of osteoid osteomas are independent of the tumor location. Surgery with resection of the nidus is the only known curative therapy. The etiological role of trauma is discussed and a review of the literature is done with 15 other cases of posttraumatic osteoid osteoma having been reported.
