Although liposarcoma is the second most common soft-tissue sarcoma in adults, it is exceedingly rare in the head and neck. According to our MEDLINE search, only 11 cases of liposarcoma of the parotid gland have been reported since 1968. We report a new case of primary atypical lipomatous tumor/well-differentiated liposarcoma of the parotid gland in a 77-year-old man. Because only a very limited number of case reports and small series have been published on liposarcoma in the head and neck, we also provide a review of the literature on this uncommon disease entity.
尽管脂肪肉瘤是成人中第二常见的软组织肉瘤，但在头颈部极为罕见。根据我们对医学文献数据库（MEDLINE）的检索，自1968年以来，仅报道了11例腮腺脂肪肉瘤。我们报告了1例77岁男性腮腺原发性非典型脂肪瘤样肿瘤/高分化脂肪肉瘤的新病例。由于关于头颈部脂肪肉瘤的病例报告和小样本系列研究发表数量非常有限，我们还对这一罕见疾病实体的文献进行了综述。
