Th yroid cancer accounts for approximately  of total cancer cases in developed countries. Th e aim of this study has been to analyze the histopathological variants of thyroid tumours with regard to gender and age. Despite their relative rarity in our material, they exhibit a wide range of morphological patterns and biological behaviour. During the period from -,  biopsy cases of thyroid tumours, which were fi xed in buffered neutral formalin and embedded in paraffi n, have been reviewed. Tissue sections (μm thick) were cut and stained with hematoxylin and eosin (H&E). Follicular adenomas have been found in ,  of cases, thyroid carcinomas in , , whereas thyroid secondary carcinomas have been found in ,  of cases. As far as histological variants of thyroid carcinomas are concerned, most frequently found were papillary carcinomas in , of cases; followed by follicular carcinomas in , of cases; follicular variants of papillary carcinomas in , of cases; medullary carcinomas in , of cases, while anaplastic and Hurthle cell carcinomas have been found in , of cases each. All histological variants of thyroid tumours occurred more frequently in women than in men. Papillary carcinoma has been found in  of female cases. Th yroid tumours in our material mainly occurred in the third, the fourth and the fi fth decade of life. Our data indicate that apart from the fact that papillary carcinomas, well diff erentiated, and characterised by relatively good prognosis, were most frequent variants, certain morphological variants of it were associated with poor prognosis.
