Umbilical endometriosis: A case report

Umbilical endometriosis is a rare disease with a prevalence of 0.5%-1%, which is more common at childbearing age in women. This condition normally presents as an over-6-cm mass, with localized symptoms and periodic pain in 81.5% of the cases. The symptoms include bleeding and inflammation.
The present case report is about a rare disease, i.e. umbilical endometriosis, in a female patient.
The patient was a 35-year-old woman treated for five years’ history of endometriosis, and presenting to Imam Reza Hospital. She had suffered umbilical pain, enlargement and change of color for three months before presentation. Two weeks before presentation, she had also experienced bleeding from the umbilicus once and ultrasound ruled out umbilical hernia. She had a fairly echogenic 15*15 mm subcutaneous mass.
Given the patient’s records and clinical history and the fact that umbilical bleeding is uncommon in adults, she was suspected to have an umbilical endometriosis and underwent surgery. The specimen sent for pathology also confirmed endometriosis.
