This document discusses the evaluation and management of benign thyroid disorders, focusing on solitary thyroid nodules. It outlines the clinical assessment, investigations including thyroid function tests, ultrasound, and FNAC biopsy. FNAC results are classified and the appropriate treatment is discussed based on classification. For solitary nodules with non-diagnostic or benign FNAC results, follow-up monitoring or surgery may be considered. Follicular or suspicious lesions require surgery and intraoperative evaluation due to the difficulty differentiating benign from malignant lesions on FNAC alone.
