Summary
Primary carpal bone tumors are rare, accounting for 0.16% of bone neoplasms. Osteoid osteoma was the most common benign tumor, while hemangioendothelial sarcoma was the most common malignant type.
Area of Science:
- Orthopedic Oncology
- Hand Surgery
- Radiology
Background:
- Primary neoplasms of the carpal bones are exceptionally rare.
- Understanding their prevalence and characteristics is crucial for diagnosis and treatment.
Purpose of the Study:
- To determine the prevalence and characteristics of primary carpal bone neoplasms.
- To identify common tumor types and locations within the carpal bones.
Main Methods:
- Retrospective review of 44 primary carpal bone tumors from a larger cohort of 26,800 bone neoplasms.
- Histologic slide and radiographic review for 36 and 29 cases, respectively.
Main Results:
- Prevalence of primary carpal bone tumors was 0.16%.
- 86% of tumors were benign, 14% malignant, with a younger average age for benign lesions (32 years) vs. malignant (58 years).
- Osteoid osteoma was the most frequent benign tumor (11 cases); hemangioendothelial sarcoma was the most common malignant neoplasm (3 cases). Scaphoid and capitate bones were the most common sites.
Conclusions:
- Primary carpal bone tumors are rare but should be considered in cases of unexplained wrist pain, particularly in younger individuals.
- Early consideration aids in timely diagnosis and management of these uncommon neoplasms.
