Endosalpingiosis is the presence of ectopic Müllerian-type epithelium resembling Fallopian tube epithelium. It usually appears as small glandular inclusions in various peritoneal sites or lymph nodes. Rarely, it is papillary in configuration, and lack of familiarity with this entity could lead to overinterpretation as a malignancy. We recently encountered a case of papillary endosalpingiosis found incidentally at laparotomy for ectopic pregnancy. Awareness of this entity is important, as it may be a diagnostic challenge.
