Co-occurrence in the same patient is exceedingly rare, with a frequency as low as 5 cases per 100 000. This case presents the first instance of a patient simultaneously afflicted with both types. Endometriosis involves the ectopic presence of endometrial tissue, with primary umbilical endometriosis (PUE) localised in the umbilicus without prior surgery, and IEM affecting the inguinal canal. In a nulliparous woman in her early 30s, lacking surgical history, the diagnosis of PUE, IEM and pelvic endometriosis was made following presentation with chronic pelvic pain and a painful umbilical nodule. This report aims to delineate the presentation, diagnosis and surgical management of patients with umbilical and IEM, shedding light on these rare manifestations.\n- Obstetrics, gynaecology and fertility\n- Obstetrics and gynaecology\nStatistics from Altmetric.com\nFootnotes\nContributors SH, MS, RP and AB-R were responsible for drafting the text, sourcing and editing clinical images, investigation results, drawing original diagrams and algorithms and critical revision for important intellectual content.
