Abstract: Thyroid FNAC is very common but its interpretation is difficult. A 16‑year‑old female patient presented with a single thyroid nodule. A cytologic diagnosis of follicular neoplasm was made on fine needle aspiration cytology (FNAC). Papanicolaou and May–Grunwald–Giemsa staining showed high cellularity, abundant micro-follicles, cell crowding and uniform nuclear morphology. Reporting was done according to Bethesda system. The distinction between Follicular neoplasm and Nodular goiter is the most common differential diagnostic problem in solitary nodules as cytological appearances overlap. Findings were suggestive of follicular neoplasm which is rare in this age group.
