Overview
The hallmarks of pheochromocytoma is recurrent episodes of sympathetic symptoms. The most common symptoms of pheochromocytoma include episodes of palpitations, sweating and headaches. Less common symptoms include cardiomypathy, episodic hypotension, symptoms of other multiple endocrine neoplasias associated diseases such as that of medullary thyroid cancer and hyperparathyroidism.
History and Symptoms
The hallmark of pheochromocytoma is recurrent episodes of palpitations, sweating, and headache.
History
Patients with pheochromocytoma may have a positive history of:
- Recurrent attacks of palpitations
- Headache and sweating
- Paroxysmal changes in blood pressure
- Family history of pheochromocytoma
- Family history of syndromes- MEN 2A, MEN 2B, NF1, VHL
Common symptoms
Common symptoms of pheochromocytoma are secondary to sympathetic nervous system hyperactivity. Symptoms usually subside in less than one hour and they may include:
- Palpitations especially in epinephrine producing tumors.[1]
- Anxiety often resembling that of a panic attack
- Sweating
- Headaches
- Paroxysmal attacks of hypertension but some patients have normal blood pressure
- Pheochromocytoma may be asymptomatic and discovered incidentally after screening for MEN patients
Less common symptoms
Less common symptoms of pheochromocytoma include:
- Cardiomyopathy: dyspnea on exertion, leg swelling, painful hepatomegaly.[2]
- Episodic hypotension.[3]
- Pheochromocytoma patients may show symptoms of other diseases associated with syndromes such as:
