A usually benign, well-encapsulated, lobular, vascular tumor of chromaffin tissue of the adrenal medulla
or sympathetic paraganglia. The cardinal symptom, reflecting the increased secretion of EPINEPHRINE and norepinephrine
, is hypertension
, which may be persistent or intermittent. During severe attacks, there may be headache
, palpitation, apprehension, tremor
of the face
in the CHEST and abdomen
, and paresthesias of the extremities
. The incidence
of malignancy is as low as 5% but the pathologic distinction between benign and malignant pheochromocytomas is not clear. (Dorland, 27th ed; DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1298)
