Summary
This case study details a rare instance of multifocal osteoid osteoma in a 31-year-old man, affecting the capitate and metacarpal bones. Recurrences highlight the challenges in completely eradicating these bone tumors.
Area of Science:
- Orthopedic Surgery
- Oncology
- Pathology
Background:
- Osteoid osteoma is a benign bone tumor typically presenting with localized pain.
- Lesions are commonly found in the long bones of the lower extremities.
Observation:
- A 31-year-old male presented with osteoid osteoma of the right capitate.
- A recurrence at the capitate required a second surgery, followed by a third osteoid osteoma in the right third metacarpal.
Findings:
- Pathological examination confirmed the nidus of osteoid osteoma in all excised specimens.
- Osteoid osteoma of the capitate is exceptionally rare, and multifocal occurrences are even more unusual.
Implications:
- While incomplete excision can explain tumor relapse, the pathogenesis of true recurrence in multifocal osteoid osteoma remains unclear.
- This case underscores the diagnostic and therapeutic challenges associated with rare presentations of osteoid osteoma.
