Umbilical Polyp: Report of Two Cases and Review of the Literature

臍部息肉:兩病例報告及文獻回顧

摘要


我們報告兩個有關臍部息肉的病例,分別為九歲女孩及21歲男孩。臍息肉是一種先天性病灶,主要是因臍—腸系膜管(omphalomesenteric duct)在肚臍脫落後未完全閉合而造成。此病灶主要是發現於孩提時期,尤其是自出生到一歲左右,而老年人較罕見。巨視觀下臍息肉看起來像小而帶有紅色的小腫塊但很少有出血現象。在此我們提出兩個病例,分別為0.6公分的突出性微紅色節結及0.5公分的似肉芽腫的息肉,他們均是自小就發現有病灶。因為臍息肉可能合併Meckel氏憩室及肚臍與腸道之間形成漏管,所以臨床醫師務必先謹慎排除其潛伏的病灶,才能實施簡單的外科手術切除以為治療的基本原則。

並列摘要


We report two patients, ages 9 years and 21 years, with umbilical polyp. An umbilical polyp is a congenital lesion resulting of incomplete closure of the omphalomesenteric duct and becomes apparent after the umbilical cord is detached. This lesion is usually found in childhood, at birth or arising during infancy, very rare in older. It is a reddish tumor of a few millimeter and seldom bleed. We reported two cases presenting with a reddish protruding 0.6-cm nodule and an ulcerative granuloma-like 0.5-cm polyp over the umbilical region, respectively, since their childhood. We consider it important to study every case in detail in order to exclude possible underlying embryonal anomalies such as Meckel's diverticulum and umbilical enteric fistula. The lesion was treated by simple surgical excision if without underlying abnormalities and was confirmed pathologically.
