Cytologic characteristics of adenoid cystic carcinoma of the cervix uteri.

Cytologic characteristics of three cases of adenoid cystic carcinoma of the cervix uteri are reviewed. The clusters of malignant cells tend to form large acini and mimic the pattern seen in histologic sections. The resemblance to cells of adenocarcinoma of the endometrium is noted. When the acinar pattern is recognized in cervical smears, adenoid cystic carcinoma of the cervix may be suspected.
