The symptoms of a sympathetic pheochromocytoma are related to sympathetic nervous system hyperactivity. [10] The classic triad includes headaches (likely related to elevated blood pressure, or hypertension ), tachycardia /elevated heart rate, and diaphoresis (excessive sweating, particularly at night, also known as hyperhidrosis ).

Multiple endocrine neoplasia type 2 (also known as "Pheochromocytoma (codons 630 and 634) and amyloid producing medullary thyroid carcinoma", [1] "PTC syndrome," [1] and "Sipple syndrome" [1]) is a group of medical disorders associated with tumors of the endocrine system.
This variant can cause medullary thyroid cancer and pheochromocytoma. Presentation can include a Marfanoid body, enlarged lips, and ganglioneuromas. [citation needed] MEN 2B typically manifests before a child is 10 years old. Affected individuals tend to be tall and lanky, with an elongated face and protruding, blubbery lips.

When the same type of tumor is found in the adrenal gland, they are referred to as a pheochromocytoma. They are rare tumors, with an overall estimated incidence of 1 in 300,000. [1] There is no test that determines benign from malignant tumors; long-term follow-up is therefore recommended for all individuals with paraganglioma. [2]
Pheochromocytoma; Paraneoplastic syndromes, in endocrine oncology: symptoms from any type of functioning (that is, hormone-producing) endocrine tumor; such tumors secrete excess hormones in a way that is homeostatically senseless, thus disrupting homeostasis (in any of many diverse ways, depending on which hormone, what dosage, and which location)
