Soft tissue chondromas are benign tumors, generally of the hands or feet, very rarely of the head and neck region. Repeated microtrauma may be as an initiating factor. The authors describe a case of a soft tissue chondroma of the chin in a 58-year-old male who had used a continuous positive airway pressure face mask for obstructive sleep apnea for 3 years. The patient presented with a hard mass on his chin for 1 year. Computed tomography imaging showed a heterogeneous enhancing mass, with calcification in the subcutaneous layer. Intraoperatively, the mass was beneath the mentalis muscle and abutted the mental nerve, without bone involvement. The diagnosis was a soft tissue chondroma. The patient recovered fully, without recurrence. The primary cause of soft tissue chondromas is unknown. The authors consider that continuous use of a continuous positive airway pressure face mask may play a role in the etiology.
软组织软骨瘤是良性肿瘤，通常发生在手或脚，很少发生在头颈部。反复的微创伤可能是一个起始因素。作者描述了 1 例 58 岁男性颏部软组织软骨瘤病例，该患者因阻塞性睡眠呼吸暂停使用持续气道正压通气面罩 3 年。患者因颏部硬块就诊 1 年。计算机断层扫描成像显示皮下层有混杂强化肿块，伴有钙化。术中，肿块位于颏舌肌下方，紧邻颏神经，无骨受累。诊断为软组织软骨瘤。患者完全康复，无复发。软组织软骨瘤的主要病因尚不清楚。作者认为持续使用持续气道正压通气面罩可能在其发病机制中起作用。
