A Patient with an Atypic Neck Mass Lesion

Acta Endo (Buc) 2020, 16 (2): 232-235
doi: 10.4183/aeb.2020.232

An 81-year-old woman presented with a history of essential hypertension for eight years and an asymptomatic multinodular goiter that had been incidentally discovered on neck ultrasonography two years ago and an-isohypoechoic mass lesion located adjacent to the right lobe inferior pole of the thyroid gland. Parathyroid adenoma or lymphadenopathy were the differential diagnosis. After two years, the endocrine surgeon decided to operate her multinodular goiter and her probably benign lesion. Intraoperatively, the blood pressure and pulse rate increased markedly and intravenous antihypertensive treatment was administered. She was discharged after blood pressure control. A 2 mm micromedullary thyroid carcinoma with C-cell hyperplasia located on the left lobe of the thyroid was detected. The aforementioned mass lesion was also reported as typical cervical paraganglioma. Because of concomitant medullary thyroid carcinoma with C-cell hyperplasia and paraganglioma the patient was subjected to genetic counseling and molecular testing for hereditary cancer syndromes. A variation of the succinate dehydrogenase gene D (SDHD) NM_003002.3: c.325C> T (Gln109Term) has been reported as the disease-causing mutation. Herein we present a case diagnosed for neck paraganglioma and medullary thyroid carcinoma after an intraoperative hypertensive crisis.
