Head & Neck Case Review

January, 2020


A 74-year-old woman presented with respiratory failure. The patient had a 3-month history of cough and progressive dyspnea with rapidly increasing neck swelling. CT Imaging revealed massive thyromegaly and lymphadenopathy with metastases to the lung, liver, kidney, and iliac bone. Patient underwent thyroid surgical resection to relieve the airway compression. Gross examination of the thyroid showed diffuse replacement by multiple masses, the largest measuring 7.6 × 5.3 × 2.7 cm, with infiltrative borders and extension into surrounding adipose tissue. H&E slides and immunostains are shown.
