ABSTRACT
Multiple endocrine neoplasia Type 1 (MEN-1) is an inherited syndrome characterized by the development of endocrine tumors of the pancreas, parathyroid, and pituitary glands. Mesenchymal tumors and adrenal neoplasms might also accompany this syndrome. However, the syndrome is rarely associated with thyroid tumors in contrary to the multiple endocrine neoplasia Type 2 that includes medullary thyroid carcinoma. This case study presents a 44-year-old woman who was diagnosed with MEN-1 on the basis of her clinical characteristics, laboratory data, and the presence of endocrine tumors. Follicular thyroid carcinoma was detected in the patient when she was being operated for nodular goiter, 12 years ago. We report this rare case which is likely the third case in the available scientific literature.
