Endometriosis is characterized by the presence of ectopic implantation of endometrial tissue, normally functioning and hormone-sensitive. Extrapelvic involvement can occur in about 12% of women with the condition. Umbilical endometriosis has been reported to account for about 0.4% to 4.0% of all endometriosis and 30% to 40% of cases of cutaneous endometriosis. It is a rare case of a disease that presents important differential diagnosis with other umbilical papular disorders, which may be primary or secondary, neoplasic or inflammatory. This paper reports the case of a patient with no comorbidities, with a diagnosis of umbilical cutaneous endometriosis, based on anamnesis, clinical and histopathological examination, showing a good evolution after complete excision of the lesion. The definitive diagnosis is based on histopathology, but immunohistochemistry may be helpful as well as abdomen ultrasound, computed tomography and magnetic resonance imaging. Surgical management is the preferred treatment.
