| Popis: | Cloacogenic carcinoma is a relatively rare lesion that arises from the cloacogenic zone of the anorectal junction. This tumor has a very high malignant potential if it is not diagnosed and aggressive therapy is not applied early.Although cloacogenic carcinomas differ in histopathology from the more common adenocarcinomas of the rectum and squamous cell carcinomas of the anus, there are no characteristic clinical signs or symptoms. However, the roentgenologic features are fairly typical and an early diagnosis can be made if these subtle but significant features are recognized in the barium enema examination.Furthermore, metastases of cloacogenic carcinoma to regional lymph nodes can be detected by lymphangiography.Even though the cloacogenic tumor has been a recognized clinicopathologic entity for more than a decade, it is relatively unknown to radiologists; yet, early roentgenologic diagnosis of the tumor as well as detection of regional metastases can be made.This report deals with the roentgenologic dia... |
