Medullary Carcinoma Thyroid surgery associated with Multiple Endocrine Neoplasia Type 2B (MEN 2B): a case report

MEN2B syndrome is a syndrome associated with systemic malignancies such as carcinoma of the thyroid and pheochromocytoma. An 18-year-old male patient with a neck mass was admitted to the Besat hospital in Sanandaj in 2015. In the clinical examination we found a long and delicate face, multiple lesions in the tongue, cheek and lips, atrophy of the temporal mandibular, and mandible protrusility in the x-ray. It was remarkable that a positive family history was not found and there were no signs and symptoms of pheochromocytoma. According to the pathology, MEN2B syndrome and final diagnosis of medullary thyroid carcinoma was confirmed and total thyroidectomy surgery and left incomplete thymectomy was conducted. With detection of non-endocrine symptoms of MEN2B and prophylactic thyroid surgery, we may expect a better prognosis. Most cases of medullary thyroid carcinoma associated with the syndrome occur in the age of 20 years. And there is a more possibility of invasion to the surrounding tissues. This condition was introduced in accordance with the patient's condition.
