title: Pheochromocytoma with angiomatous features. A case report and ultrastructural study.
abstract: A functional pheochromocytoma of the adrenal gland but with an angiomatous histologic pattern was studied by light and electron microscopy. Although this tumor had typical clinical and gross anatomic features, its light microscopic appearance was unique and, to our knowledge, has not been previously described. Fine structural study provided insight into the intracellular pathways of catecholamine granule formation.
