It occurs in up to 15% of menstruating women and often goes undetected. Some cases of soft-tissue involvement have been reported, particularly in the skin and subjacent tissues of surgical scars. However, we came cross a 42-year-old female patient with millimetric focal lesions in a groin hernia sac. A case report and a review of the literature are presented. Although definitive diagnosis still requires biopsy, the patient’s cyclic symptoms and history of previous uterine surgery should suggest the correct diagnosis.\nSimilar content being viewed by others\nReferences\nKamio M, Nagata T, Yamasaki H, Yoshinaga M, Douchi T (2009) Inguinal hernia containing functioning, rudimentary uterine horn and endometriosis.
