title: [Osteoid osteoma on distal phalanx tip of second toe, without scintigraphy fixation].
abstract: Osteoid osteoma is a very small painful, benign tumor, located preferentially on long bones. Cases on the phalanxes of the toes are very rare. Pain takes up nearly all the clinical presentation. Poor clinical signs and atypical location make diagnosis difficult and delayed. Sometimes, it can be confused with local infection. Various additional tests are described to help diagnosis. Technetium 99-m scintigraphy coupled with CT is the key exam with high sensitivity and morphological accuracy. We report on the case of a 10-year-old boy with an atypical location of osteoid osteoma on the distal phalanx tip of the second toe, without scintigraphy fixation and obvious nidus on X-ray and CT scan.
