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 2 5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 0 9～ 0 2 9mm ,远小于腺体部分切除的安全边界 (5～ 10mm)。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～ 10mm的腺体部分切除 。
Objective\ The purpose of this study was to offer pathological reasons for partial parotidectomy adopted in parotid 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_center were measured and recorded.Results\ The range of extra_envelope infiltration and budding was limited in 0 09～0 285 mm out of tumor capsules, which was 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.
