[Perineal neoplasms].

The literature on perineal neoplasms is reviewed and their incidence, the method and effectiveness of their surgical treatment analyzed. The prognosis of perineal neoplasms is tragic: according to published data 50% of the patients die within two, 92% within four years. The benign or malignant nature of perineal tumours can be judged only on the basis of histological tests. Attention is drawn to the necessity of the early surgical removal of perineal tumours. In the case of a 66-year old woman the histological diagnosis was gelatinous adenocarcinoma. To the best of the knowledge of the authors no similar case has been reported in the literature.
