Umbilical endometriosis is an extremely rare type of endometriosis, with an incidence of 0.5% to 1% of all endometriosis cases. This report describes a case of umbilical endometriosis that developed in the absence of previous abdominal or uterine surgery. Clinical diagnosis of umbilical endometriosis is difficult and the differential diagnosis of umbilical lesions can be confusing, thus a high level of clinical suspicion is required.
