Radiation-associated recurrent parathyroid adenoma.
Recurrent parathyroid adenoma occurred in a patient who had received radiation treatments to the lateral aspect of the pharynx for lymphoid hyperplasia at the age of 10 years. The interval between the development of the first and second adenomas was 20 years. Although an association between head and neck irradiation and primary hyperparathyroidism is known, we believe this to be the first report of recurrent hyperparathyroidism in an irradiated patient.
