title: [Cloacogenic carcinoma. Radiological appearance during double-contrast enema].
abstract: Radiographic appearances at double contrast enema of 8 cases of anorectal cloacogenic carcinoma are described. In all cases tumor was radiologically identified as a neoplastic lesion, but the correct histologic diagnosis was not reached in any case. Radiological features of the cloacogenic carcinoma are: the evident submucosal mass, the poor mucosal involvement and the eccentricity of the lesion. However, the characteristics of the tumor are not peculiar and radiologic diagnosis of the nature of tumor can only be suspected.
