[Synchronous polyneoplasia of the thyroid gland: problems of diagnosis and therapy].

Thyroid carcinoma concurrent with synchronous polyneoplasia is quite rare and not fully understood. There are 15 cases of such carcinoma on the records of the Center (2000-2005) (papillary and medullar - 9, papillary and follicullar -3, papillary and anaplastic - 1, papillary - 1 and unidentified well differentiated carcinoma - 1). Still another patient had a combination of Hodgkin's disease (nodular sclerosis, cellular stage) and papillary microcarcinoma dicceminated to lymph nodes. Problems of diagnosis and therapy are discussed.
