A case report of Villar’s nodule in a woman without surgical history

Abstract

Villar’s nodule is an umbilical endometriosis without anterior or ongoing pelvicendometriosis. The primitive location of this nodule at the umbilical level is rare. Its etiopathogenesisremains unclear.PRESENTATION OF CASE: We report a case of umbilical endometriosis with unusual clinical expressionin a woman in the reproductive years with no surgical history and no known history of endometriosis.Endometriosis manifested as progressive transformation of the normal umbilicus into several small nod-ules, with bleeding coinciding with the menstrual cycle. The diagnosis was confirmed by histology andsurgical treatment consisted of omphalectomy.DISCUSSION: Umbilical endometriosis is a rare disease that occurs naturally in patients with pelvicendometriosis. Etiopathogenesis of the disease is still unclear. In our patient, the appearance of the nodulewas impressively, by a gradual transformation of the normal aspect of the umbilicus, into several small,slightly pigmented, firm, painful and concomitantly bleeding nodules during periods of menstruation. Inthe literature, this multinodular or budding form would be of exceptional observation.CONCLUSION: The characteristics of the umbilical tumor, associated with the cyclical nature of tumorbleeding in a patient without previous history of endometriosis, strongly suggest the diagnosis of Villar’snodule, but the confirmation is still histological. The treatment is always surgical and recurrence is veryrare
