Thyroid Nodules in Severely Obese Patients: Frequency and Risk of Malignancy on Ultrasonography.

: We aimed to compare the thyroid ultrasonographic findings of severely obese nonobese individuals, and the frequency, characteristics, and risk of malignancy in detected nodules.: Case-control study including 67 adults with severe obesity (body mass index [BMI] ≥ 35 kg/m) and 67 nonobese controls (BMI < 30 kg/m). The participants underwent ultrasound evaluation of the thyroid and cervical subcutaneous tissue.
