Abstract
Three enteric‐type neoplasms of the lower female genital tract are described; an enteric adenocarcinoma of the cervix, an enteric adenocarcinoma of the vagina and a tubulo‐villous adenoma of the vagina. The two adenocarcinomas were characterized by the presence of columnar cells with a prominent brush border and an abundance of goblet cells. The tubulovillous adenoma was identical to similar lesions found in the large intestine. The criteria for diagnosis of an enteric adenocarcinoma of the female genital tract are discussed and it is concluded that the histochemical demonstration of o‐acetylated sialomucin is the most specific marker of intestinal differentiation. It is suggested that enteric tumours of the cervix arise from foci of gastrointestinal metaplasia. Enteric tumours of the vagina are more likely to develop from cloacal remnants.
