    Author: Abdel Aleem A, el Sheikh S, Mokhtar A, Ghafouri H, Saleem M.
    Journal: Z Kinderchir; 1985 Oct; 40(5):303-7. PubMed ID: 4072431.
    Abstract:
    We present 5 uncommon cases: One case of perineal canal in a female; two cases of perineal groove in females, one with normal anus and another with ectopic perineal anus. Two cases of perineal canal in males. The canal is deep in the perineum, runs forward above the root of scrotum, close to the floor of the urethra (which is normal), and opens on the undersurface of the penis. One of them is associated with covered anus incomplete with anocutaneous fistula as well opening on the scrotal raphe. In all 5 cases the perineal canal or gutter opens posteriorly in the ectodermal anal canal, immediately below the line of anal valves. A third look to the origin of these conditions will be discussed versus the 1st and 2nd looks of Stephens and Chatterjee. Embryological and histopathological studies will support our point of view.
