We report the case of an umbilical polyp, derived from omphalo-mesenteric remnants in an one-month-old female child. This rare abnormality results from a closure defect of the vitelline duct. The vitelline duct normally closes between the 5th and the 7th weeks of intra embryonic development but can lead to several pathologies in case of closure defects, giving rise to abdominal (Meckel diverticulum, vitelline cyst) or umbilical symptoms (umbilical fistula, umbilical sinus and umbilical polyp). These disorders have a 2% incidence, and may induce clinical symptoms of varied gravity ranging from clinical silence to acute abdomen. We seized the opportunity of this rare clinical observation to review the nosology of vitelline duct defects at the light of embryologic data.
我们报告了一例脐息肉病例，该息肉源于一名1个月大女童的卵黄管遗迹。这种罕见的异常是由于卵黄管闭合缺陷所致。卵黄管通常在胚胎发育的第5至7周之间闭合，但如果存在闭合缺陷，可能会导致多种病理情况，引发腹部症状（梅克尔憩室、卵黄管囊肿）或脐部症状（脐瘘、脐窦和脐息肉）。这些疾病的发病率为2%，可能引发从无症状到急腹症等不同严重程度的临床症状。我们利用这一罕见的临床观察机会，根据胚胎学数据对卵黄管缺陷的分类学进行了回顾。
