Overview

The histological analysis in de Quervain's thyroiditis may show inflammatory cell infiltration and hurthle cells. Fine needle aspiration cytology helps to differentiate between the benign and malignant nodules.

Other Diagnostic Studies

Fine needle aspiration cytology

Fine needle aspiration is usually done under ultrasound guidance and the sample is sent for cytology. It helps to differentiate benign thyroid nodules from the malignant lesions.

Microscopic Pathology

Microscopically, thyroid glands in de Quervain's thyroiditis may show:

• Destruction of the follicular epithelium.
• Loss of the follicular integrity.
• Patchy distribution of non-caseous granulomas.
• Granuloma comprises of colloid, small lymphocytes, neutrophils, and macrophages with or without epithelioid features.
