Myxofibrosarcoma has been recently described as a distinct histological entity and commonly affects the extremities and trunk of the elderly. It is, however, rare in the head and neck (2.8%) region, and we are unaware of any reports of it presenting as a parotid mass. The epitheloid variant accounts for less than 3% of myxofibrosarcomas. We report a case of a 78/F presenting with an epitheloid myxofibrosarcoma in the parotid gland. The clinical presentation was of a parotid lump of 9-month duration, and the diagnosis was made following thorough histological assessment. We present what we believe to be the first reported case of a (epitheloid) myxofibrosarcoma affecting the parotid gland and highlight its diagnostic features and outcome of treatment.
黏液纤维肉瘤最近被描述为一种独特的组织学实体，常见于老年人的四肢和躯干。然而，它在头颈部（2.8%）区域罕见，且我们未意识到有任何关于其表现为腮腺肿块的报道。上皮样变型占黏液纤维肉瘤的比例不到3%。我们报告一例78岁女性患者，其腮腺出现上皮样黏液纤维肉瘤。临床表现为持续9个月的腮腺肿块，经全面组织学评估后作出诊断。我们呈现了我们认为首例报道的累及腮腺的（上皮样）黏液纤维肉瘤病例，并强调其诊断特征和治疗结果。
