Mucinous adenocarcinoma of the endometrium with intestinal differentiation: a case report.
Mucinous differentiation of endocervical type has been well documented in endometrial carcinoma. However, we describe an unusual case of adenocarcinoma of the endometrium showing diffuse histological, immunohistochemical, and ultrastructural evidence of intestinal differentiation. Although intestinal differentiation has been described in mesodermally derived tissues including endocervix, ovary, and urinary tract, it has not been reported in normal endometrium. One previous case has been reported showing this pattern in endometrial carcinoma. Possible histogenetic mechanisms of this pattern are discussed.
