[Tumors of the sacrococcygeal region (author's transl)]

In the world literature is reported about 584 tumors of the sacrococcygeal region, 484 of them are analysed exactly. The symptoms of the various tumors are about the same, pain and nerval irritation were seen in the most cases. Rectal-digital examination mostly leads to diagnosis. Computertomography is of special diagnostic value since some years. Because of the localisation of the tumor therapy often is difficult. Operation is the only way to remove the tumor and should be done so radically as possible. Radiation therapy may induce malignant degeneration. Adjuvant chemotherapy till now is without of any any effect. In the paper we report about the very seldom malignant meningeoma of the sacrum, in the literature we could not find any other case. Besides this and the 584 cases of the literature there is reported about 4 other own cases of sacrococcygeal tumors, one neurofibroma and three giant cell tumors of the Os sacrum.
