Abstract 한글 요약
[INTRODUCTION AND IMPORTANCE] Multiple Endocrine Neoplasia Type 2 (MEN2) is a rare autosomal dominant neoplastic syndrome resulting from RET gene mutations, marked by medullary thyroid carcinoma (MTC) and increased risk of other endocrine tumors. MEN2 includes subtypes MEN2A, MEN2B, and familial MTC. Prophylactic thyroidectomy is recommended for MEN2A due to high MTC risk.
[CASE PRESENTATION] A 38-year-old woman with a family history of thyroid cancer presented with headaches, sweating, and palpable breast mass. Exam revealed skin lesions. Lab abnormalities and imaging indicated a large adrenal mass and thyroid nodules. Inconclusive biopsies led to left adrenalectomy, confirming pheochromocytoma. Subsequent total thyroidectomy revealed MTC.
[CLINICAL DISCUSSION] This case represents rare MEN2B presentation, featuring MTC, pheochromocytoma, mucosal neuromas, and marfanoid habitus. Genetic testing for RET mutations is crucial with a positive family history. MEN2A individuals undergo prophylactic thyroidectomy due to high MTC risk. Although rare, pheochromocytoma can be an initial MEN2 manifestation, indicated by paroxysmal symptoms. Surgical resection is the treatment.
[CONCLUSIONS] The patient's successful adrenalectomy followed by total thyroidectomy confirmed MTC. Thorough evaluation, including inconclusive initial findings, emphasizes imaging, and biopsies. Early detection and appropriate management optimize MEN2 outcomes.
