Cancers thyroidiens radio-induits

We describe thyroid carcinomas observed in two male patients after cervical irradiation in infancy. In the first case, irradiation was given for cervical angioma and in the second case, for enlarged thymus. A long time interval (16 and 43 years) elapsed between irradiation and the detection of the epitheliomas. The anatomopathological diagnosis was, for the first patient, papillo-vesicular epithelioma and for the second one, anaplastic carcinoma.
