Introduction:

Endometriosis is one of the most frequent gynecological pathologies, understood as an intrapelvic implantation of endometrial tissue, sensitive to hormonal influence in most cases. At the extrauterine level, it is characterized by the presence of endometrial glands and stroma in the non-gynecological organs or tissues. However, the skin corresponds to one of the sites with the least frequency of implantation, either primary or secondary, with the incidence of cutaneous endometriosis being calculated at the umbilical level in <1% of the cases.

Case presentation:

A 36-year-old female patient presented to the General Surgery department with a two-year history of dark brown, raised skin lesions in the umbilical region, which she described as painful, and bleeding at the time of the menstrual cycle. Despite having been resected twice, the condition still persisted.

Discussion:

Umbilical primary cutaneous endometriosis represents 0.5%-1.0% of all patients with ectopic endometriosis, with the navel being one of the least common implantation sites. This condition affects about 5%-15% of women of childbearing age, and 3%-5% women of menopausal age. The most common clinical presentation is based on the palpable mass, umbilical bleeding, regular or irregular abdominal pain. Associating extrapelvic endometriosis with the presence of pelvic endometriosis, only about 20% of the patients will have the latter.
