Chondrosarcomas constitute the second-most-frequent malignant bone tumors, representing about 10% of all malignant bone tumors. The most frequent localizations comprise the trunk, pelvis and limbs. Metastatic disease usually occurs in the lung; metastases to other localizations are seen occasionally. Manifestation in the head and neck area, either as primary tumor or metastasis, is very rare. A case of parotid gland metastasis in multiple enchondromatosis secondary chondrosarcoma (CHOSA) G-III of the left femoral bone is presented. A 79-year-old male patient reported to our clinic with a rapidly progressing mass in the left parotid gland. A superficial parotidectomy was performed and the entire tumor resected. Histopathological examination revealed nodular infiltration of the parotid by chondrosarcoma consistent with metastatic disease. Review of the literature shows that this is the first report of such a case.
软骨肉瘤是第二常见的恶性骨肿瘤，约占所有恶性骨肿瘤的10%。最常见的发病部位包括躯干、骨盆和四肢。转移性疾病通常发生在肺部；偶尔也可见转移至其他部位。在头颈部区域，无论是作为原发性肿瘤还是转移瘤，其表现都非常罕见。本文报告一例左股骨多发性内生软骨瘤继发软骨肉瘤（CHOSA）G-III伴腮腺转移的病例。一名79岁男性患者因左腮腺肿物迅速增大前来我院就诊。行腮腺浅叶切除术并完整切除肿瘤。组织病理学检查显示腮腺被软骨肉瘤结节状浸润，符合转移性疾病。文献复习表明，这是此类病例的首例报道。
