This paper describes primary umbilical endometriosis, a rare condition defined by ectopic endometrial tissue in the umbilicus, and highlights the challenge of clinically diagnosing cutaneous endometriosis due to variable presentations. It reports a 50-year-old woman with no prior pelvic surgery who developed a painful umbilical nodule that bled in synchrony with her menstrual cycles. After total excision, histopathological examination established the diagnosis. This paper is centrally about endometriosis — specifically primary umbilical endometriosis presenting with menstruation from the umbilicus.

Abstract Primary umbilical endometriosis is a rare disorder and is defined as the presence of ectopic endometrial tissue within the umbilicus. The clinical diagnosis of cutaneous endometriosis remains challenging due to the variable clinical appearance and symptoms of the condition. A 50-yearold female patient with no history of previous pelvic surgery was admitted to our outpatient clinic because of a painful nodule on her umbilical region, bleeding with her menstrual cycle. After a total excision and histopathological examination of the patient’s lesion, the diagnosis of primary umbilical endometriosis was established. This case highlights the importance of including primary umbilical endometriosis in the differential diagnosis in women with a painful umbilical nodule.
