Multiple squamous cells in thyroid fine needle aspiration: Friends or foes?

ConclusionThyroid aspirates with predominance of squamous cells cannot be classified in the current Bethesda categories. Even when interpreted as atypical or equivocal, the squamous cells present in our small case series were mostly benign. The only malignant case was easily identified cytologically because of its higher degree of differentiation. The most common pitfall for atypical squamous cells in these aspirates was squamous metaplasia in the setting of Hashimoto thyroiditis and degenerative changes. Diagn.
