Paratubal cysts are incidental, common and benign lesions with few cases of borderline tumor and adenocarcinoma been reported in the literature. Herein, we are discussing a case of an 85 years old woman who visited her Obstetrics and Gynecologist for a chief complaint of post-menopausal bleeding. Physical examination revealed a slightly enlarged uterus. The diagnosis of fibroids were made on ultrasound. A total hysterectomy with bilateral salpingo-oophorectomy was performed without complications. The gross examination of the specimen was most remarkable for multiple intramural fibroids and a right simple paratubal cyst meausirng 1 × 1 cm. Microscopical evaluation of the paratubal cyst showed a simple cyst lined by stratified cuboidal epithelium with mild cytologic atypia and no stromal invasion, findings consistent with serous borderline tumor rising in a paratubal cyst. Due to the small size of the tumor and its confinement to the cyst, a follow-up was advised. Serous borderline tumors arising in paratubal cyst are very rare with only eight cases reported in the literature. Their existence should be acknowledged to plan patient treatment and outcome.
输卵管旁囊肿是偶然发现的常见良性病变，文献中仅有少数交界性肿瘤和腺癌病例的报道。在此，我们讨论一例85岁女性患者，她因绝经后出血为主诉就诊于妇产科。体格检查发现子宫轻度增大。超声检查诊断为子宫肌瘤。行全子宫切除术加双侧输卵管卵巢切除术，无并发症。标本大体检查最显著的发现是多个肌壁间肌瘤和一个大小为1×1厘米的右侧单纯性输卵管旁囊肿。对输卵管旁囊肿的显微镜评估显示，囊肿为单层立方上皮衬里的单纯囊肿，有轻度细胞学异型性，无间质浸润，这些发现符合起源于输卵管旁囊肿的浆液性交界性肿瘤。由于肿瘤体积小且局限于囊肿内，建议进行随访。起源于输卵管旁囊肿的浆液性交界性肿瘤非常罕见，文献中仅报道了8例。应认识到它们的存在，以便规划患者的治疗和预后。
