Umbilical Endometriosis in a Surgically Naïve Multiparous Young Female.

The existence of functional endometrial tissue outside the uterus is known as endometriosis. It is a benign estrogen-dependent gynecological condition that affects 5%-10% of women who are of reproductive age. Endometriosis often affects the ovary and fallopian tubes, although it can also occur in nonpelvic areas. The most typical location for extra-pelvic endometriosis is the abdomen. Umbilical endometriosis is a rare condition accounting for 0.5%-1.0% of all cases of endometriosis. In 3% of cases, there is a chance of malignant change. This disorder's precise etiology is uncertain. Recurrent discomfort and swelling around the umbilicus are the classic manifestations. In this instance, we describe a patient with primary umbilical endometriosis (PUE) who had cyclical bleeding and swelling over the umbilicus and was surgically naive. This case will demonstrate how, particularly in surgically naïve instances, diagnosis of PUE is frequently delayed due to ignorance of the entity.
