Anomaly of Omphalomesenteric Duct Remnant in a 5-year-old Male Child: A Case Report

Abstract

Umbilical polyps are the remnants of incomplete obliteration of the omphalomesenteric duct (synonymous to vitellointestinal duct). They are firm, reddish nodules found in the depth of the umbilicus which can often be mistaken for granulomas. In our index case, a 5-year-old male patient presented with umbilical mass from 4 month of life which on physical examination showed red, erythematous, single swelling. Ultrasonography diagnosed as umbilical granuloma. Excision was done and sent for Histopathological Examination(HPE).The final diagnosis of omphalomesenteric duct remnant consistent with umbilical polyp was made upon histopathological examination. The histopathology of Vitellointestinal Duct (VID) anomalies/omphalomesenteric duct remnant presents a complex diagnostic challenge for the pathologist.
