中文摘要

目的 为腮腺多形性腺瘤腺体切除范围提供病理学依据。方法 通过显微镜对25例原发腮腺多形性腺瘤连续病理切片的观察,尤其是重点观察和测量腺瘤包膜外浸润、出芽生长情况,并探讨有无原发多中心分布。结果 ①包膜外浸润及出芽生长的具体扩展范围为:0·09~0·29 mm,远小于腺体部分切除的安全边界(5~10 mm)。②原发多中心分布2例,但具有分散程度小、有统一融合包膜的特点。结论 腮腺多形性腺瘤瘤体外5~10 mm的腺体部分切除,可以达到根治的效果。

英文摘要

Objective The purpose of this studywas to offer pathological reasons for partial parotidectomy adopted in pa- rotid pleomorphic adenoma treatment.Methods Continuous slices from 25 cases of primary parotid pleomorphic adenoma were carefully examined and the extra-envelope infiltration, the budding and the primary multi-centerwere measured and recorded.Re- sults The range of extra-envelope infiltration and buddingwas limited in 0·09~0·285 mm out of tumor capsules, whichwas far less than the safe boundary(1 cm)of the partial parotidectomy. Two cases with multi-centers were found, but all the centers were aggregated together and encapsulated in a united envelope.Conclusion Partial parotid parotidectomy is a safe method and can remove the tumor completely in parotid plemorphic adenoma treatment.
