Primary carcinoma of the vagina is relatively rare among female genital malignancy, and early cancer is much more rare. Out of a total of 65 cases of vaginal cancer treated in the Cancer Institute Hospital, Tokyo, there were four cases of early cancer.
Average age of patients with vaginal cancer is approximately the same, compared to those with cervical carcinoma, and there was a tendency for them to have married young and a high rate of no experience in pregnancy or delivery. The lesion was present in the posterior upper third of the vaginal wall in the majority, and the four cases of early cancer had the lesion in the posterior vornix. Cytological examination was most useful for the diagnosis of early cancer and the above four cases showed positive cytological findings. The cytodiagnostic evidence in these four cases was chiefly parabasal type of malignant cells similar to cervical carcinoma in situ, and a mixture of parabasal type malignant cells and keratinizing atypical cells.
