粘液表皮样肿瘤(mucoepidermoidtumor)又称粘液表皮样癌(mucoepider-moid carcinoma),是较常见的涎腺恶性肿瘤。自1945年Stewart 等将其从广义的混合瘤中分出,创用粘液表皮样肿瘤一名以来,文献报告的病例数以千计。许多作者从临床及组织学表现、组织化学、超微结构等方面进行了大量研究,从而对其生物学行为有了逐步深入的了解。但在其组织学分型及治疗方面尚存一些分歧。现综合有关文献作一简要介绍。一、发病概况粘液表皮样肿瘤约占所有涎腺肿瘤的3～15%,在大涎腺肿瘤中,约占5～10%,其中90%发生于腮腺,其余发生于颌下腺。在
Mucoepidermoid tumor, also known as mucoepidermoid carcinoma, is a common malignant tumor of parotid gland. Since Stewart et al. separated it from the mixed tumors in a broad sense in 1945, since the creation of a mucoepidermoid tumor, the literature has reported thousands of cases. Many authors have conducted extensive researches in clinical and histological performance, histochemistry, ultrastructure, and other aspects, which have led to a gradual understanding of their biological behavior. However, there are some differences in histological classification and treatment. The relevant literature is briefly summarized. First, the incidence profile of mucous epidermoid tumors account for about 3 to 15% of all salivary gland tumors, in the salivary gland tumors, accounting for about 5-10%, of which 90% occurred in the parotid gland, the rest occurred in the submandibular gland. in
