Pathophysiology

Pathogenesis

The exact pathogenesis of de Quervain's thyroiditis is unclear. Cytotoxic T cell recognition of viral and cell antigens presented in a complex leading to thyroid follicular cell damage has been proposed as the pathogenesis of de Quervain's thyroiditis. De Quervain's thyroiditis is usually preceded by a viral prodrome. Various viral infections are associated with the de Quervain's thyroiditis including mumps, adenovirus, Epstein–Barr virus, coxsackievirus, cytomegalovirus, influenza, echovirus, and enterovirus.

Genetics

• De Quervain's thyroiditis is associated with the histocompatibility antigen (HLA) B35.
• In some cases of De Quervain's thyroiditis HLA B15/62 positivity was also reported.

Pathology

The primary pathology of de Quervain's thyroiditis is:

• Destruction of the follicular epithelium
• Loss of the follicular integrity
