The general outline of the thyroid gland is preserved but the right lobe is grossly enlarged by nodules of tumour tissue; there are areas of necrosis present. The left lobe appears normal. The tumour is compressing the trachea.
This woman presented at the age of 72 with increased difficulty in swallowing and occasional episodes of dyspnoea which became acute and she was admitted in a state of anxiety because of difficulty in breathing. Before a tracheotomy she had a cardiac arrest and subsequently developed a respiratory arrest which was irreversible. She had known of a swelling in her thyroid gland for some 50 years. At autopsy, metastatic deposits were found in lung; heart, adrenals and local lymph nodes.
