Liesegang rings in the female genital tract. A report of three cases.

Three cases of Liesegang rings (LRs) within the female genital tract are reported; only one similar case has been previously documented. The patients were 32-57 years of age and underwent operations for ovarian endometriosis (two cases) and uterine leiomyomas (one case). Innumerable eosinophilic, acellular, ring-like structures, similar to previously described LRs, were found on microscopic examination and were confined to an endometriotic cyst (two cases) or the mucosa of a fallopian tube involved by chronic salpingitis (one case). Liesegang rings within the female genital tract, as in other sites, occur within cysts or within areas of inflammation. These structures have been confused with and should be distinguished from parasites and foreign material on histologic examination.
