This paper reports a case of primary umbilical cutaneous endometriosis in a 38-year-old nulliparous woman with a seven-year history of infertility, severe dysmenorrhea, and a one-year history of monthly bleeding from a painful, multilobate cutaneous nodule at the umbilicus. Despite infertility-associated workup with normal hormonal profile and hysterosalpingogram, diagnosis was confirmed histologically after surgical excision, which had a good outcome. The paper also provides a review of related literature on cutaneous and atypical endometriosis presentations, while acknowledging diagnostic difficulty when patients are asymptomatic. This paper is centrally about endometriosis — it focuses on primary umbilical cutaneous endometriosis presenting with catamenial bleeding and confirmed histologically.

Abstract

Primary umbilical cutaneous endometriosis is a rare umbilical endometrioma that affects women who are within the reproductive age group. It may be associated with infertility and severe dysmenorrhea and can be difficult to diagnosed in an asymptomatic patient. We report a case of a 38-year-old nulliparous with seven years history of infertility and severe dysmenorrhea. Her hormonal profile assay and hysterosalpingogram results were normal while her husband semen analysis was also within normal range. She complained of monthly bleeding from a painful rubbery multilobate cutaneous nodule on the umbilicus of one year duration. She was diagnosed of cutaneous endometriosis. The diagnosis was confirmed histologically and she had surgical excision with good outcome.
