Osteoid osteoma of the distal phalanx of the finger: a diagnostic challenge.

Abstract

Osteoid osteomas of the distal phalanx of fingers are uncommon. An extensive review of the literature indicates that the diagnosis of osteoid osteoma of the distal phalanx is often delayed for several months to years (average 34.3 months). Pain is the most common finding (92 percent), followed by swelling and clubbing (75 percent). Relief of pain by aspirin was indicated in 10 patients (42 percent). Multiple operations were done in 7 patients prior to the appropriate diagnosis and treatment. A typical case report is presented to illustrate the difficulties in diagnosis and treatment of this benign bone tumor. A better awareness of this tumor may prevent unwanted delays in diagnosis and unnecessary operations.
