title: Painless osteoid-osteoma in phalanx of finger. A case of unusual presentation and symptomatology.
abstract: 1. Painless osteoid-osteoma is a very rare entity but must be considered. 2. Finger localization for this tumor has been reported in very few cases. Differential diagnosis with other tumors or osteomyelitis should be kept in mind. 3. Eng block excision in similar cases should be seriously considered. 4. While the reason for the absence of pain in some cases has not been precisely determined, the lack of nerve fibers in this case suggests that this may be an important factor.
