Umbilical endometriosis mimicking as papilloma to general surgeons: A case report.

INTRODUCTION Cutaneous or umbilical endometriosis is a rare entity that is often overlooked because of chronic abdominal pain. We present a case of umbilical hernia that presented to the general surgeons due to chronic abdominal pain and nodule in the umbilicus, which was clinically diagnosed as umbilical papilloma. CASE PRESENTATION A 48-year old multiparous Caucasian woman presented with painful nodule in the umbilicus for two and half years. The nodule was excised and the histopathological diagnosis was umbilicus endometriosis. CONCLUSION Umbilical endometriosis is a very rare disease but should be considered as a differential diagnosis in women presenting with umbilical swelling.
