RETRORECTAL CYST-HAMARTOMA - REPORT OF A CASE WITH ADENOCARCINOMA DEVELOPING IN ONE

Among the different pathologic structures of the presacro-coccygeal sp ace retrorectal cystic hamartomas are uncommon lesions. These cysts ar e most likely derived from remnants of the embryonic tail-gut although an association to teratomas may exist. We describe the clinicopatholo gic features of a retrorectal cystic hamartoma with malignant transfor mation in a 60 year old female patient. The literature is reviewed and etiology, diagnosis and operative management are discussed.
