Scaphoid enchondroma.
Enchondromas are rarely found in carpal bones. This paper reports a case with scaphoid enchondroma and reviews three cases from previous literature. Three of the patients with scaphoid enchondromas presented with pathologic fractures after traumatic events. Each enchondroma had characteristic histopathologic findings. It is important to realize that although enchondroma is usually a painless lesion, it weakens the cortex of the involved bone, facilitating fracture. Thus, when cystic scaphoid fractures are encountered, enchondroma must be part of the differential diagnosis.
