Challenges of Diagnosis and Treatment Choice in Riedel‘s Fibrosing Thyroiditis: Clinical Case Examples

Background . Clinically distinct Riedel’s fibrosing thyroiditis is extremely rare, accounting for only 0.05 % of histologically verified cases, as follows from the real clinical practice and literature. Classic typified by a marked compression syndrome, which may lack at initial disease stages. A problematic verification often conduces to diagnostic and, especially, therapeutic malpractice, illustrated two hereby analysed cases.
