Adenomyomatous, lower uterine segment and endocervical polyps in cervicovaginal smears

To the best of our knowledge, the specific features of polyps in cervicovaginal smears have not been described; that fact prompted us to undertake this study. Fifty-seven cases of polyps below the uterine fundus with cytohistopathologic correlations were analyzed. The tissue diagnoses were 2 cases of adenomyomatous, 2 cases of lower uterine and 53 cases of endocervical polyps. In the cervicovaginal smears, adenomyomatous polyps presented as cohesive fragments with frayed edges, revealing spindle cells with bipolar cytoplasmic processes. Lower uterine segment polyps showed peculiar tissue fragments composed of several fractured arterioles connected by sheets of small stromal cells. Endocervical polyps presented as smooth-bordered, polypoid tissue fragments, lined at the outermost layer with simple columnar cells, sandwiched within a pale intermediate zone and packed at their inner core with numerous small, dark stromal cells. This specific finding, however, was observed in only one case. The remaining 52 patients had no specific findings in their smears.
