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.
