BACKGROUND: @entity957 of the thyroid is a rare @entity5 that needs to be distinguished from other @entity5 . CASES: Two males aged 65 and 68 years presented with an enlarged right lobe of the thyroid. Thyroid scintigraphy revealed a cold nodule. @entity5 was suspected. Fine needle aspiration (FNA) revealed numerous clusters and isolated malignant cells, dyskeratotic cells and deposits of eosinophilic granular keratin material. Subtotal thyroidectomy was performed. Histologic findings confirmed the cytologic diagnosis of @entity957 . CONCLUSION: @entity957 of the thyroid is a rare @entity5 . FNA findings of this @entity5 were not reported before. FNA study cannot help to differentiate primary from metastatic @entity957 of the thyroid.
