Osteoid osteoma is a benign bone tumor. A few cases of metacarpal osteoid osteoma have been reported, but the phalanges are the most frequent sites in the hand, followed by the carpal bones. We report a case of an osteoid osteoma of the right first metacarpal bone in a 32-year-old woman. The clinical and radiographic findings along with the pathology results are presented. At the 1 year follow-up there was no evidence of recurrence. Finally, Osteoid osteoma of the metacarpal bones should be considered in the diagnosis of chronic pain in the hand of a young patient, presenting with or without a history of previous injury Copy Right, IJAR, 2017,.

Introduction:-Osteoid osteoma represents 10% of all benign bone tumors with a localization in the wrist and the hand in 6% to 13% of reported cases only [1,2]. The phalanges are the most frequent sites [3], followed by the carpal bone and finally the metacarpals which are the least common sites [4]. We report a cas of osteoid osteoma of the first metacarpal in a young patient and describe the clinical presentation, radiological findings and successful outcome after surgical excision of the lesion Case Report:-A 32 year-old woman, whitout any antecedent of injury, was referred to our hospital last year with history of pain in her first right finger. The pain increased at night and was reduced by non-steroidal anti-inflammatory agents. The physical examination was normal and the radiographs showed an extension of the metaphysis of the right first metacarpal bone (Figure 1a).
