Abstract

Tailgut cysts in retrorectal or presacral space are rare and the derivatives of the embryonic post-anal gut. It is thought to arise from vestiges of embryonic hindgut. The lesions were usually multicystic and lined by a variety of epithelial types, including ciliated columnar, mucin-secreting columnar, transitional, and squamous epithelium. Tailgut cyst has been found in men and women of various ages but is more common in women and is usually associated with middle age. They may be the source of the chronic perirectal symptoms and rarely undergo malignant change, so early diagnosis and accurate evaluation is important. Complete surgical resection should be considered because of a long term risk of malignant change. We report two cases of tailgut cyst.
