Overview
Common physical exam findings of pheochromocytoma include tachycardia, hypertension, and orthostatic hypotension.
Physical Examination
Appearance of the Patient
- Patients may appear tired, weak, diaphoretic and anxious.[1]
- Patients may appear quite well if the disease is asymptomatic.
- Patients may appear flushed due to associated increase in erythropoietin secretion.[2]
- Patients may appear obese due to associated type2 diabetes mellitus and Cushing's syndrome.[3]
Vital Signs
- Tachycardia with a regular pulse. Irregular pulse may occurr in supraventricular tachycardia.
- Tachypnea if malignant secondaries are found in the lung. Dyspnea occurs in patients with complicated heart failure and cardiomyopathy.
- Rapid strong equal pulse
- High blood pressure with normal pulse pressure
- Hypotension occurs due to fluid contraction.
Skin
- Jaundice secondary to deranged liver function in case of metastasis to the liver.
Head
- Facial flushing
- Scleral icterus in case of metastasis to the liver
- MEN2 patients associated with mucosal neuromas show multiple lips and tongue neuromas.
Neck
- Congested neck veins in patients with cardiomyopathy[4]
- Painless lymphadenopathy if malignant secondaries found in the neck (rapid increase in the size of the node. Prevalence of malignancy in lymph node biopsies performed is 60%[5]
- Thyromegaly/thyroid nodules if MEN patients due to medullary thyroid cancer.[6]
Lungs
- Asymmetric chest expansion / decreased chest expansion if malignant secondaries are found in the lung.
Heart
- Chest tenderness upon palpation in MEN1 patients due to hyperparathyroidism.
- Palpation: Precordial heave especially at apex due to left ventricular hypertrophy in long standing patients.
- Auscultation: normal S1 and accentuated S2 due to high systemic resistance.
Abdomen
- Abdominal distention in patients with primary hyperparathyroidism associated constipation or Hirschsprung disease.
- Abdominal tenderness in the lower abdominal quadrants in MEN2 patients with Hirschsprung disease.[7]
- A palpable abdominal mass in the lower abdominal quadrant.
- Guarding may be present.
- Hepatomegaly if malignant secondaries found in liver.
- Diarrhea caused by gastrointestinal secretion of fluid and electrolytes, and flushing in medullary thyroid cancer patients.[8]
Back
- Point tenderness in MEN1 patients with hyperparathyroidism.
