Concurrent Adrenal Pheochromocytoma and Papillary Adenocarcinoma of the Thyroid in a 20-Year old Man

Abstract

A 20-year-old man was admitted to Kyushu University Hospital with complaints of severe headache and episodic hypertension (200/100 mmHg). Ultrasonograms and computed tomographs revealed tumors in the left adrenal region and in the right lower lobe of the thyroid gland. Total thyroidectomy and left adrenalectomy were performed. The excised thyroid tumor and adrenal tumor were pathologically diagnosed as papillary adenocarcinoma and pheochromocytoma, respectively. A chromosome analysis revealed no karyotypic abnormality. Whereas the world literature records such occurrences in women, this is the first report of a simultaneous occurrence of pheochromocytoma and papillary adenocarcinoma of the thyroid in a young man.
