[Radiogenic sarcoma of the thyroid (author's transl)].

A sarcoma in the region of the thyroid, observed 30 years after radiotherapy in a patient with syringomyelia is presented. Even after low dose radiation in childhood and adolescence tumours of the thyroid frequently can be diagnosed. They rarely occur in adults, because apparently of a long latent period. This case is thought not to be a specific thyroid tumour.
