Abstract
Intestinal (tailgut) cysts or retrorectal cystic hamartomas are rare benign lesions that are included in the category of developmental cystic lesions. Their origin is still uncertain, although several hypotheses have been proposed to explain their development. They are located mainly in the presacral (retrorectal) space and predominately affect middle-aged women (40-60 years).
Taking into account location and histological characteristics, the main differential diagnoses include epidermoid cysts, duplication cysts and teratomas.
Malignant transformation of these lesions is rare and preferentially into adenocarcinoma and neuroendocrine tumors.
We present a case of an intestinal cyst associated with a well-differentiated neuroendocrine tumor (G1) in a 63-year-old woman.
