Overview
Common physical exam findings of pheochromocytoma include tachycardia, hypertension, and orthostatic hypotension.
Physical Examination
Appearance of the Patient
- Patients appear tired, weak, sweaty with anxious appearance[1].
- Patients may appear quite well in asymptomatic patients.
- Patients may appear flushed due to associated increase in erythropoietin secretion.[2]
- Patients may appear obese due to complicated type2 DM and Cushing syndrome.[3]
Vital Signs
- Tachycardia with a regular pulse. The irregular pulse occurs in supraventricular tachycardia.
- Tachypnea/bradypnea if malignant secondaries 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
Head
- Abnormalities of the head may include:
- Facial flushing
- Scleral icterus if liver malignant secondaries affected liver functions.
- MEN2 patients associated with mucosal neuromas show multiple lips and tongue neuromas.
Neck
- Congested neck veins in cardiomyopathy associated patients.[4]
- Lymphadenopathy if malignant secondaries found in the neck (firm, a rapid increase in the size of the node and painless). Prevalence of malignancy in lymph node biopsies performed is 60%.[5]
- Thyromegaly/thyroid nodules if MEN patient associated with medullary thyroid malignancy.[6]
Lungs
- Asymmetric chest expansion / Decreased chest expansion if malignant secondaries are found in the lung.
Heart
- Chest tenderness upon palpation in MEN1 patients associated with hyperparathyroidism.
- Palpation: Pericardial 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.
