Thyroid nodules are common and their incidence has increased due to various factors. Systematic approach to the work-up of thyroid nodules is necessary to decrease overdiagnosis as well as over treatment. Applying the trifecta of history, physicial examination and high-resolution ultrasound (HRUS) as well as fine needle aspiration biopsy (FNAB) with added TSH measurement is important in the work-up. HRUS is a central part in the diagnostic approach, being able to risk classify nodules and selecting nodules for FNAB. Systematic analysis of aspirates is necessary to simplify communication between cytologists and clinicians.
