Osteoid osteoma of the pisiform: A case report

Background: Osteoid osteoma is an uncommon benign bone-forming tumor of the musculoskeletalsystem but it is the most common primary bone tumor of the carpal region. However, only seven cases ofits pisiform involvement have been described.Case: We present a 19 year-old male patient with osteoid osteoma of the pisiform which initially couldnot be detected in any diagnostic study for long standing wrist pain. The patient was treated withexcision and curettage. In 1 year of follow-up, the patient was asymptomatic without recurrence.Conclusion: In cases with long standing ulnar wrist pain, one should consider osteoid osteoma of thepisiform in differential diagnosis. If an OO is suspected, thin slice CT scan in initial evaluation would bevaluable in preventing the patient from misdiagnosis or delay in diagnosis.© 2016 Turkish Association of Orthopaedics and Traumatology.
