Summary
Aneurysmal bone cysts (ABCs) are rare benign tumors. This study reports the first documented case of an ABC in the pisiform bone of the hand, successfully treated with surgery.
Area of Science:
- Orthopedic Surgery
- Oncology
- Hand Surgery
Background:
- Aneurysmal bone cysts (ABCs) are uncommon benign primary bone tumors.
- Hand involvement by ABCs is exceptionally rare.
- The pisiform bone is a particularly unusual site for ABCs.
Observation:
- A literature review revealed no prior descriptions of ABCs in the pisiform.
- The case involved a 19-year-old male with an ABC in the left pisiform bone.
- Diagnosis was confirmed through clinical and radiological evaluation.
Findings:
- Surgical excision was performed for the pisiform ABC.
- The patient experienced an uneventful recovery post-surgery.
- This case highlights the successful treatment of a rare bone tumor.
Implications:
- This report establishes the pisiform as a potential, albeit rare, location for ABCs.
- Prompt diagnosis and surgical treatment are crucial for favorable outcomes.
- Understanding this rare presentation is vital for managing risks like pathologic fracture and ulnar nerve compression.
