Extraskeletal chondroma of the hand. Case report and review of the literature.
The pathogenesis, clinical features, and histology of extraskeletal chondromas, along with a review of the literature, demonstrate that extraskeletal chondromas are rare, benign cartilaginous tumors found most frequently in the hands and feet. A case of extraskeletal chondroma is described in a patient who had a volar carpal mass of long duration, with an acute inflammatory episode that subsided with antiinflammatory medication. Roentgenograms and computed tomographic scanning revealed the presence of soft-tissue calcifications. An excisional biopsy was performed, revealing a benign lobular cartilage tumor with marked cellularity and prominent calcification that are characteristic of these lesions.
