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.
骨外软骨瘤的发病机制、临床特征和组织学，以及文献综述表明，骨外软骨瘤是罕见的良性软骨肿瘤，最常发生于手足部位。本文描述了一例骨外软骨瘤患者，该患者掌侧腕部有一长期肿物，并伴有一次急性炎症发作，经抗炎药物治疗后炎症消退。X线片和计算机断层扫描显示存在软组织钙化。进行了切除活检，结果显示为良性小叶状软骨肿瘤，具有这些病变特征性的明显细胞增多和显著钙化。
