Inguinal endometriosis: a rare entity of a common condition .

Abstract

A woman in her mid-40s experienced a painful lump in the right groin area for 5 years, with exacerbation during menstruation, coughing and sneezing. Initial treatment with depot methylprednisolone acetate injection was ineffective. 2 years later, at a different hospital, an endometriotic mass was identified in the right inguinal region, and excision was not performed because of the propensity for vascular injury; instead, three doses of depot medroxyprogesterone acetate significantly alleviated the pain. When she presented to our hospital, a provisional diagnosis of right inguinal endometriosis was made after an ultrasound examination. A multidisciplinary approach involving a surgeon was employed for excision surgery, with meticulous attention given to avoiding femoral vein injury.This case study underscores the importance of collaboration between specialties for accurate diagnosis and effective surgical management of inguinal endometriosis. Preoperative imaging is useful, but the final diagnosis can be confirmed only after surgical excision and histopathology.
