Liesegang rings (LRs) are laminated precipitation structures well recognized in the field of chemistry. I present a rare case of a 53-year-old female who consulted for pelvic pain and abnormal uterine bleeding. The pelvic ultrasound revealed intramural and submucous uterine leiomyomas, and she underwent hysterectomy and bilateral salpingo-oophorectomy. Gross examination showed several paratubal cysts, which contained multiple eosinophilic concentrically spherical and oval structures of variable size compatible with LRs. In the female genital tract only 8 cases with LRs have been reported. This is the first documented case of LRs appearing in paratubal cysts. LRs formation should be taken into account during the histopathologic examination of paratubal cysts and not be misdiagnosed as a parasitic infection or foreign material within the female genital tract.
莱塞尔环（LRs）是化学领域中广泛认可的层状沉淀结构。我报告了一个罕见的病例，一名 53 岁女性因盆腔疼痛和异常子宫出血就诊。盆腔超声显示子宫壁内和黏膜下子宫肌瘤，她接受了子宫切除术和双侧输卵管卵巢切除术。大体检查显示多个输卵管旁囊肿，其中包含多个嗜酸性同心球形和椭圆形结构，大小不一，符合 LRs。在女性生殖道中，仅报道了 8 例 LRs。这是首例出现在输卵管旁囊肿中的 LRs 病例。在输卵管旁囊肿的组织病理学检查中应考虑 LRs 的形成，而不应误诊为女性生殖道内的寄生虫感染或异物。
