Why do i get temporary yellow skin? not yellow in the eyes but the whole body. i have no anemia, but a pheochromocytoma, what can it be? pheo related?

Pheochromocytoma: You need to get this pheo treated. The bursts of adrenaline can be fatal. The bursts of adrenaline can make your skin pale, which may be perceived as yellow, depending on your natural color. There are characteristic skin tingling sensations, or itching with pheo. Other hormones can be abnormal too (pth, calcitonin) in certain varieties of pheo. This condition is rare, so see your doctor.
