Type-2A multiple endocrine neoplasia (MEN-2A) syndrome is a rare autosomal dominant inheritance disease characterized by the presence of pheochromocytoma (PHEO), medullary thyroid carcinoma (MTC), and parathyroid adenoma or hyperplasia. In patients with MEN-2A, PHEO is frequently asymptomatic and bilateral, and MTC is multifocal, usually representing the first manifestation of the disease.

Herein, we present the scholar clinical case of a 38-years-old woman with MEN-2A syndrome addressed for clinical examination and primary biochemical investigation following the diagnosis of a mutation in codon 634 of gene RET exon 11. Patient showed increased plasma normetanephrine (14.7 nmol/l, normal <10.9), noradrenaline (680 ng/l, normal <400), adrenaline (257 ng/l, normal <90), dopamine (64 ng/l, normal <50), chromogranin-A (114 ug/L, normal <100), and calcitonin values (241 ng/L, normal <10). At clinical examination, small non-toxic goiter (afterwards confirmed by cervical ultrasonography) was...
