Diagnosis of Candida thyroiditis by fine needle aspiration.

Infective thyroiditis is an uncommon condition, and fungal infection of the thyroid gland is rare. We present a case of Candida thyroiditis in a patient with leukaemia and review the three previous reports of this entity in the world's literature. We conclude that Candida thyroiditis should be considered in immunosuppressed patients with known infection who develop fever and neck pain, that gallium scanning may help localise the infection to the thyroid gland; that fine needle aspiration is a useful diagnostic test, and that thyroid dysfunction is common with Candida thyroiditis.
