粘液表皮样瘤是由Stemarf氏在1945年做为涎腺肿瘤的一种特殊类型而提出的,早期将其分为良性及恶性两型,后来Foote及Frazell氏提出组织学上良性粘液表皮样瘤仍有转移的可能性,因此目前多数作者都将粘液表皮样瘤按恶性肿瘤治疗。发生在大诞腺的粘液表皮样瘤一般认为是起源于导管上皮细胞,发生在小涎腺者则起源于导管上皮细胞或者粘液上皮细胞。
Mucoepidermoid tumors were proposed by Stemarf as a special type of salivary gland tumors in 1945. They were divided into benign and malignant types in the early stages. Foote and Frazerl later proposed histologically benign mucoepidermoid tumors. There is still a possibility of metastasis, so most authors currently treat mucoepidermoid tumors as malignant tumors. Mucinous epidermoid neoplasias that occur in the major mucinous glands are generally thought to originate from ductal epithelial cells, and in the parotid glands they originate from ductal epithelial cells or mucous epithelial cells.
