title: Subperiosteal osteoid osteoma of the hamate: a case report.
abstract: Osteoid osteoma is uncommon in the hand. The lesion can arise from either cortical or cancellous bone or subperiosteally. The latter localization is extremely rare in the hand, with only 4 reported cases in the English-language literature. Furthermore, characteristic radiographic findings of a central lucency surrounded by reactive sclerosis often emerge only late in the process, or not at all. Consequently, the diagnosis of osteoid osteoma of the hand can be delayed. We report a case of a subperiosteal osteoid osteoma of the hamate in which the diagnosis was delayed 2 years.
