Mesenchymal chondrosarcoma (MCHS) is a highly aggressive, malignant, cartilaginous tumor that represents about 1% of all chondrosarcomas. Only about 50 cases of MCHS of the jaw have been reported in the English-language literature; maxillary tumors are much more common than mandibular tumors. We present a new case of MCHS of the mandible that arose in a 22-year-old woman whose initial two biopsies did not reveal the features of the tumor. The diagnosis was made only after an incisional biopsy.
间叶性软骨肉瘤（MCHS）是一种侵袭性很强的恶性软骨肿瘤，约占所有软骨肉瘤的1%。英文文献中仅报道了约50例颌骨MCHS；上颌肿瘤比下颌肿瘤更为常见。我们报告一例发生于一名22岁女性的下颌骨MCHS新病例，该患者最初的两次活检未显示出肿瘤特征。仅在切开活检后才做出诊断。
