title: Coexistence of multiple omphalomesenteric duct anomalies.
abstract: The omphalomesenteric duct is an embryonic structure which connects the yolk sac to the midgut. The omphalomesenteric duct attenuates between the 5th and 9th week of gestation. Failure of the omphalomesenteric duct involution, either partial or complete, results in various omphalomesenteric duct remnants including Meckel's diverticulum, patent vitelline duct, fibrous band, sinus tract, umbilical polyp and cyst. Omphalomesenteric duct remnants are present in 2% of the population but related diseases have seldom been reported in adults. The simultaneous presence of sinus tract, omphalomesenteric cyst, fibrous ligament and Meckel's diverticulum has, according to authors' knowledge, never been reported. We present a case of a 23 years old male with persisting umbilical discharge for 2 years in whom there was coexistence of the above mentioned anomalies of the omphalomesenteric duct.
