Multifocal follicular carcinoma of thyroid following radiotherapy for Hodgkin's disease

A 21-year-old white male developed multifocal follicular carcinoma of the thyroid gland 17 years after receiving neck irradiation (3000 rad) for Hodgkin9s disease. The tumour was unique in that follicular carcinoma has not previously been reported as having a multifocal origin, even after high dose radiotherapy.
