Overview
Common physical exam findings of pheochromocytoma include tachycardia, hypertension, and orthostatic hypotension.
Physical Examination
Appearance of the Patient
Vital Signs
- Tachycardia with regular pulse. Irregular pulse occurs in supraventricular tachycardia.
- Tachypnea / bradypnea if malignant secondaries found in lung
- Rapid strong equal pulse
- High blood pressure with normal pulse pressure
- Hypotension occurs due to fluid contraction
Skin
- Jaundice if liver malignant secondaries affected liver functions.
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
- Jugular venous distension
- Lymphadenopathy if malignant secondaries found in neck (firm , rapid increase in size of the node and painless)
- Thyromegaly / thyroid nodules if MEN patient associated with medullary thyroid malignancy[1]
Lungs
- Asymmetric chest expansion / Decreased chest expansion if malignant lung secondaries are found in lung
Heart
- Chest tenderness upon palpation in MEN1 patients associated with hyperparathyroidism
- Palpation: Pericordial 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 constioation or hirschsprung disease
- Abdominal tenderness in the lower abdominal quadrants in MEN2 patients with hirschsprung disease[2]
- 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.[3]
Back
- Point tenderness in MEN1 patients with hyperparathyroidism
