title: Diffuse large B-cell lymphoma in the thyroid gland associated with primary hyperparathyroidism.
abstract: We report a case of primary hyperparathyroidism associated with a malignant lymphoma in the thyroid gland. A 68-year-old woman was admitted to hospital with a cervical mass. Ultrasound and computed tomography (CT) revealed a hypoechoic, multinodular tumor in the left thyroid gland. A gallium-67 citrate scintigram revealed intense radioisotope uptake in the thyroid tumor. Histological examination of biopsy specimens indicated that this tumor was a large B-cell lymphoma. The coexistence of parathyroid adenoma in this patient was revealed by a sestamibi scintigram, performed prior to chemotherapy. Following the complete remission of the lymphoma by chemotherapy, we carried out an excision of the single parathyroid adenoma. To our knowledge, this is the first report to describe a malignant thyroid lymphoma associated with primary hyperparathyroidism.
