[The incidence rate of thyroid microcarcinoma during surgery benign disease]

Thyroid microcarcinoma are well-differentiated tumors less than 1 cm in diameter. A retrospective analysis was performed on patients operated of benign thyroid disease at the Center for endocrine surgery, Institute of endocrinology, Clical Center of Serbia in Belgrade, from January 1st to December 31st 2004, in order to establish the incidence of microcarcinoma. Indications for surgery were euthyroid multinodular goiter in 201 patients, thyroiditis in 31, thyroid adenoma in 178, Graves disease in 89 and Plummers disease in 79 patients. The results of this study, demonstrate that in 13.4% of the patients operated for goiter, 6.4% operated for thyroiditis, 5.6% for thyroid adenomas, 9.0% for Graves disease and 7.0% of the patients operated for Plumers disease, the presence of a microcarcinoma was noticed in the definitive histopathologic examination. The results obtained are in line with the current knowledge of high incidence of thyroid microcarcinoma.
