Multiple Endocrine Neoplasia Type 2b: A Rare Case Report
Multiple endocrine neoplasia Type 2b is a rare syndrome caused by mutations in RET proto oncogene. It is a rare case, which
is found 1 in 30,000. We report a case of 23-year-old male patient with goiter, right lower chest pain, paroxysmal spells and
hypertension. On examination, mucosal neuromas and Grade 2 hard goiter were observed. Patient’s thyroid profi le was normal.
Fine-needle aspiration cytology thyroid showed medullary carcinoma of the thyroid. Calcitonin levels were found to be elevated.
Contrast enhanced computed tomography neck showed 28 mm × 20 mm heterogeneous mass in the right lobe of the thyroid.
Histopathology and immune histochemistry confi rmed the pheochromocytoma.
