[Gluteal fistulo-gummatous syndrome (malignant dysembryoma)].

Abstract

The authors present the case of a 61 years old patient with fistulo-gummutous lesions with ulcer formation and pus formation in the right buttock, loss of weight and asthenia. The lesions appeared six months after a violent blow on the right buttock. General examination of the ano-rectal region, including sigmoidoscopy and fistulography, together with histo-pathological examination, revealed the existence of a perirectal muciparous carcinoma developing on embryonic glanduilform remains, situated in the right perinee-rectal region. The special interest of this case resides in its rareness and the unusual clinical appearance of gummatous fistula.
