 Thyroid nodules and thyroid cancer rarely appear in Graves’ disease.  In contrast, in Hashimoto’s thyroiditis is commonly nodular goiter, and described the association of thyroid cancer often. nosing-pediatric-thyroid-cancer_08.html

 Evaluation of thyroid morphology in Graves’ and Hashimoto’s diseases.  To study the frequency of thyroid malignant processes in Basedow-Graves’ disease.  Evaluation of possible correlation between the antithyroid treatment and nodular goiter in Basedow-Graves’ disease.

The retrospective study included 145 patients with Graves’ disease and 100 with Hashimoto’s hospitalized in Clinic of Endocrinology, Department of Targu-Mures, between January 2009 and December 2013.

We followed:  Hormonal assessment: TSH, free-T4, free-T3  Antithyroid antibodies: TRAb, anti-TPO  The results of: -thyroid ultrasonography (US) - fine needle aspiration biopsy - histopathological examination  Specific treatment followed.

BASEDOW Thyroid morphology in graves disease. 35% was nodular goiter and 65% diffuse goiter

HASHIMOTO

In basedow, 30% of the nodular goiter was uninodular, and 70% multinodular.

It is possible to be a correlation between the antithyroid treatment and the forming of nodular goiter. In our study, 64% of the pacients with nodular goiter received chronic antithyroid treatment

In our study, 2% of the thyroid nodules was malignant. And the type of thyroid cancer was in 100% papillary carcinoma thyroid.

 At one time, thyroid cancer in Basedow-Graves’ disease was considered to be extremely rare, but this perception is beginning to change. Several studies have reported both an increased incidence of nodules and of thyroid cancer in patients with Graves' disease, with cancer rates varying from as low as 1% to as high as 9% of cases Ultrasonographic screening for detection of thyroid cancer in patients with Graves' disease.

Management of simple nodular goiter: current status and future perspectives. Endocr. Rev 2003;24: Many studies have been published in wich the ability to predict whether a thyroid nodule is benign or malignant on the basis of US findings was evaluated. There is no evidence in the literature to suggest that malignancy is based on nodule size.. In our study we found a nodule size of less than 1 cm to be significant for malignancy.( 1) Several US features have been foun to be associated with an increased risk of thyroid cancer, including the presence of microcalcification However, the sensitivities, specificities and negative and positive predictive values for these criteria are extremely variable from study to study..

 The feature with the highest sensitivity, in the range of 69.0%-75.0%, is solid composition.  The feature with the highest positive predictive value, 41.8%-94.2%, is the presence of microcalcifications.  The combination of factors improves the positive value to some extend.

 However thyroid nodules appear rarely in Graves’ disease, in our cohort it was met rather frequent, a possible explanation could be the methimazole therapy.  Thyroid nodules in Graves’ disease present a lower rate of malignancy.  Nodular goiter in Hashimoto’s thyroiditis appeared more frequently. Our study supports the results of others recent studies.
