Diagnosis problems in a case of minimal deviation adenocarcinoma of the cervix.

We present the diagnostic problems in a case of minimal deviation adenocarcinoma of the cervix. Histopathologic exam of the tumor, made on serial sections, revealed a dense and profound proliferation of the glandular structures that were lined by endocervical type epithelia with minimal cellular and nuclear atypia. The aspect suggested the diagnosis of minimal deviation adenocarcinoma endocervical type; in order to confirm the diagnosis we immunohistochemical investigate the tumor for CEA, CA125, Ki67, ER and PR. The results indicated focal positivity for CEA, CA125 lack of immunostaining for ER and PR and Ki67 positivity with a low index of proliferation. We can conclude that all these markers are useful in the diagnosis, excluding the benign endocervical lesions.
