Soft tissue chondroma is a rare benign tumor of the cartilage. It occurs commonly in distal extremities of middle-aged patients. It is usually asymptomatic and grows slowly, making early diagnosis difficult. We report a 10-year-old patient with a 1-year history of a subungual soft tissue chondroma on her left fifth finger. The lesion arose from nail bed and distal nail matrix, resulting in nail dystrophy. Magnetic resonance imaging revealed a soft tissue tumor in the subungual region and soft tissue chondroma was diagnosed, based on histopathologic findings. Dermatologists should consider soft tissue chondroma in the differential diagnosis of subungual tumors of children.
软组织软骨瘤是一种罕见的软骨良性肿瘤。它常见于中年患者的四肢远端。通常无症状且生长缓慢，导致早期诊断困难。我们报告一名10岁患者，其左小指有1年的甲下软组织软骨瘤病史。病变起源于甲床和远端甲母质，导致指甲营养不良。磁共振成像显示甲下区域有一个软组织肿瘤，根据组织病理学结果诊断为软组织软骨瘤。皮肤科医生在儿童甲下肿瘤的鉴别诊断中应考虑软组织软骨瘤。
