Expression of the von Hippel-Lindau Tumor Suppressor Gene in Nonneoplastic and Neoplastic Lesions of the Thyroid.

abstract：:Synchronous occurrence of medullary and papillary carcinoma of the thyroid gland is very rare. We describe two cases of synchronous medullary and papillary carcinoma of the thyroid. In both cases, medullary carcinoma and papillary carcinoma were separate in the thyroid but mixed in some of the lymph node metastases. A...

The key pathogenetic feature is the activation of thyroid-specific T-cells by properly presented endogenous thyroid antigens. There is strong indication that thyrocytes themselves present self-antigens, based on the finding of antigen prese...
