自１９８３年６月～１９９３年６月，我院共收治卵巢粘液性囊腺瘤患者１８６例，合并腹膜粘液瘤者１２例，约占６．４％。其中９例手术时肿瘤已破溃，３例为卵巢粘液性囊腺瘤单纯切除术后复发，全部病例均有腹腔广泛转移及大量胶冻样腹水。外观酷似晚期恶性肿瘤，但其肿瘤结节的组织学形态为良性，细胞分化良好，其预后与晚期癌相比有明显区别，所以应重视其良性特点，积极进行治疗。 From June 1983 to June 1993, 186 cases of ovarian mucinous cystadenoma were treated in our hospital, and 12 cases had peritoneal myxoma, accounting for 6.4%. Of the 9 cases, the tumor had been ruptured at the time of surgery, and 3 cases had recurrence of ovarian mucinous cystadenoma after simple resection. All the cases had extensive peritoneal metastasis and a large amount of jelly-like ascites. The appearance resembles advanced malignant tumors, but the histological morphology of the tumor nodules is benign and the cells are well differentiated. The prognosis is obviously different from that of advanced cancers, so we should pay attention to its benign characteristics and actively treat it.
