Abstract
A clinicopathological study of 6 cases of cloacogenic carcinoma and review of the literature was undertaken. These tumors arise from transitional epithelium of the pectinate line. The tumors are often deceptive in the beginning and may often resemble small abscesses, fissures or fistulas. Often they appear outside the mucosa and skin. Histologically, they are well, moderately or poorly differentiated. Local excision is adequate for small noninfiltrate tumors. Pelvic radiation, combined with surgery for lesions > 2 cm with local extension and/or pelvic nodes, controls the pelvic disease. Well and moderately differentiated tumors have a better prognosis than squamous cell carcinoma. Overall survival rate is .apprx. 50%. Cure rate depends on the size of the lesion, differentiation of tumor, depth of invasion, duration of the symptoms, nodal involvement, lymphatic or vascular invasion and contiguous organ invasion. Cloacogenic carcinoma is a better term than other names used in the literature for this tumor.
