We present the case of a 38-year-old woman with a progressively tender swelling of the thyroid gland, who was treated as Riedel's thyroiditis based on two fine needle aspirations and a core biopsy. She was later found, on partial thyroidectomy, to have nodular sclerosis classical Hodgkin's lymphoma.
Keywords: ear; malignant and benign haematology; nose and throat; thyroid disease.
