title: Umbilical endometriosis with giant degenerated uterine leiomyomas: A case report.
abstract: •We present an unusual case of umbilical endometriosis and huge uterine leiomyomas with marked hydropic and cystic degeneration.•Although umbilical tumors are uncommon, the differential diagnosis should include umbilical endometriosis, particularly in reproductive-age women.•Umbilical endometriosis can be suspected from the clinical presentation, but the diagnosis should be confirmed with histological examination.
