Abstract: We report a case of multiple endocrine neoplasia (MEN) type 2A and summarize the clinical characteristics,
diagnosis and treatment of this condition. The diagnosis of MEN type 2A relies on a comprehensive evaluation of the findings
of ultrasound, CT and laboratory examinations, and early diagnosis and treatment is critical to improving the prognosis.
Genetic testing of RET is the gold standard for diagnosis of MEN type 2A and 2B. Surgical intervention currently remains the
primary choice of treatments of this disease.
