β¦ Synopsis
Synchronous thyroid and thymic malignancy following childhood thymic irradiation has only been reported in two known cases previously, with a third case identified here. A rationale is presented for following these radiated patients as they age with thyroglobulin and thyroid-stimulating hormone (TSH) levels as a measure of risk of the development of nodular thyroid disease and, if such occurs, for an aggressive surgical approach. There exists a growing population at risk atributable to the success of radiation treatment of Hodgkin's and pediatric head and neck tumors. The question is raised regarding the theoretical benefits of thyroid suppressive therapy in this group at risk. With the instructive case presented, radical surgery for either thymic or thyroid carcinoma and careful monitoring for decades-late local recurrences of thymoma are suggested.

## Abstract ## Background Carcinoma showing thymic-like elements (CASTLE) is a rare tumour of the thyroid of thymic origin. The histological appearance of this tumour may be similar to that of squamous cell carcinoma of the thyroid, but outcome associated with CASTLE is more favourable. ## Method
The concentration of T-cell receptor rearrangement excision DNA circles (TRECs) in peripheral blood mononuclear cells (PBMCs) is currently known to be a marker of recent thymic emigrants. We evaluated the hypothesis that TREC values would be lower in childhood T-cell hematopoietic malignancies than
