[ report about a rare case of tail gut cyst [TGC] in a 90- year-old man with sacrum ulceration]

ABSTRACT

Tail gut cyst [TGC] is a non common cystic lesion with post anal origin which is occurred in retro rectal region. In this article we studied a 90-year-old man with a tail gut cyst who presented with post sacral ulcer. The patient did not cooperate well with taking history. For further evaluations the patient underwent surgical treatment for detriment and the region was drained off and repaired. At operation retro rectal cystic mass was excised for pathologic studies. Although the incidence of malignancy in TGC is extremely rare, it should be considered in differential diagnosis of retro rectal tumors especially in middle-aged women
