Introduction: Medullary thyroid carcinoma (MTC) is an uncommon thyroid malignancy arising from calcitonin-producing parafollicular cells. Micro-MTC is defined traditionally as MTC that measures ≤1 cm and represents a very rare entity. Ultrasound-guided fine-needle aspiration biopsy cytology (FNAB-C) sensitivity is about 63% for MTC and can be improved by measurement of calcitonin in the needle washout (FNA-CT). The value of FNA-CT in micro-MTC has not been studied. Our a...

Introduction: The Bethesda System for Reporting Thyroid Cytopathology (TBSRT) allows the correlation between six individual diagnostic categories with the risk of malignancy, and offers a standardized management algorithm for each category. Atypia of undetermined significance (AUS) and follicular neoplasm categories are considered indeterminate categories, with varying malignancy rates and subtypes.Aim: To establish the malignancy rate and subtype of can...
