Transitional-cell cloacogenic carcinoma of the anal canal: Case report.
A case is presented of transitional-cell cloacogenic carcinoma of the anal canal in a 66-year-old woman. Eight years previously she had received radiation therapy for early carcinoma of the uterine cervix, but there was no evidence of recurrence. The rectal carcinoma was therefore regarded as a second primary malignant tumor. This point in differential diagnosis was considered important because of its bearing on the plan of treatment. After abdominoperineal resection of the tumor, the prognosis seemed favorable.
