Rare case of Inguinal Endometriosis Lump : Case Report and Literature review

Background : Endometriosis is usually found in intrapelvic structures such as the ovaries, peritoneum, gynecological organs and the pouch of Douglas. We report an unusual case of endometriosis in the right inguinal region. \nCases : A 36-year-old woman with a history of laparoscopic surgery for endometriosis 4 years ago complained of catamenial pain and a mass in the right inguinal region, and her symptoms fluctuated with the menstrual cycle. An indistinct firm mass palpable in the right inguinal region. Ultrasound examination revealed a 2 × 1 cm mass in front of the pubic area on the lower edge of the rectus abdominis muscle. In a patient with an inguinal subcutaneous mass who complains of periodic changes in symptoms, endometriosis should be considered in the differential diagnosis. \nConclusion : The low incidence of inguinal endometriosis is one of the considerations in the different diagnosis of painful inguinal hernias in the inguinal area in women with childbearing age. The diagnosis of endometriosis can be demonstrated clearly on High-Definition Ultrasound by trained personnel. Surgery is the optional treatment and is curative in this case. \nKeywords: Endometriosis; extra pelvic endometriosis; Inguinal subcutaneous Lump ; Inguinal Endometriosis, Inguinal Hernia
