Giant Malignant Pheochromocytoma: A Unique Case Report from Turkey

ABSTRACT

Catecholamine-secreting tumors are rare neoplasms that occur in less than 0.2% of hypertensive patients. While pheochromocytomas are rare neoplasms in the adrenal gland, giant pheochromocytomas are much less common. In this report, we present the case of a 38-year-old man who had a 29x18x12 cm giant malignant pheochromocytoma. During an examination for hematuria, a large mass was detected incidentally in the right adrenal gland of the patient. This mass was diagnosed as pheochromocytoma and proved to be one of the largest pheochromocytomas reported so far; hence, its notification has been considered significant for the medical and research professionals across the world.
