摘　　要：目的 :研究女阴侵袭性血管粘液瘤的临床特点与病理特征 ,以免误诊漏诊。方法 :对女阴侵袭性血管粘液瘤 2例行手术切除 ,并行光镜和免疫组化检查。结果 :术中见肿瘤呈无包膜生长 ,剖面苍白色、胶质样 ,有粘液性间质分隔。 1例因肿瘤浸润周围组织 ,术后持续性反复出血 ,且于 5月内复发。病检示瘤细胞呈梭形或星形排列于粘液样背景中 ,核无异形性或分裂相 ,其间有中等以上厚壁血管。免疫组化染色示Vimentin(+ )、S10 0 (- )。结论 :侵袭性血管粘液瘤罕见 ,侵袭性与复发性是其重要的临床特点。术前了解肿瘤浸润范围十分必要。治疗以扩大的局部外阴切除为宜 ,并需长期随访。Objective:To study aggressive angiomyxoma of the vulva occuring in women as well as its clinical and pathological characteristics for avoiding misdignosis and missing diagnosis.Method:A detail clinical and pathological analysis was performed on two patients with aggressive angiomyxoma after operations.Results:Rowing with nonencapsulation, the tumour was segregated by myxoid stroma.The cut surface showed a soft,gray white,colloid.In the second case ,there was continuous hemorrhage repeatedly after operations in that tumors had infiltrated into peripheral tissue elapsing within five months.Histologically,the tumour was composed of spinde shaped or stellate shaped cells in myxoid stroma with medium sized, thick walled vessels.There was no nuclear atypia or mitotic activity.Immunohistochemically,vimentin was positive and S 100 protein was negative.Conclusion:Aggressive angiomyxoma is a distinctive and rare soft tissue tumour. It is necessary that the infiltrating range of tumour should be understood before opperations.The recommended treatment of aggressive angiomyxoma of the vulva is wide local excision with tumour free margins and long term follow up is needed.
