Squamous papilloma of the cervix uteri. A two year prospective cytological study.

Squamous papilloma of the cervix uteri were found in 27 patients from 147,813 consecutive cervical smears, an incidence of 1 : 5,475. These were young women (16 to 35 years of age), 17 (63%) of whom were pregnant. When this group was compared with a matched control group, a statistically significant increase in trichomonad infections and a reduction in fungal infections were observed. Smears from every patient with cervical papilloma showed dysplasia of squamous cells which, with one exception, regressed to a lesion of lesser severity, or reverted to normal. The role of cytology, histology and clinical history in the diagnosis and management of this lesion is discussed.
