Overview
Common physical examination findings of psoraisis include erythematous, scaling papules and plaques on the skin.
Physical Examination
Appearance of the Patient
- Patient with psoriasis may look distressed and anxious.
Vital signs
- High-grade fever with generalized pustular psoriasis.[1]
- Tachycardia with regular pulse.[1]
- Tachypnea.
- Kussmal respirations may be present in patients with comorbid diabetes and DKA.
- High-output cardiac failure in erythroderma.[2]
Skin
- A diagnosis of psoriasis is usually based on the appearance of the skin. There are no special blood tests or diagnostic procedures for psoriasis. Sometimes a skin biopsy, or scraping, may be needed to rule out other disorders and to confirm the diagnosis. Skin from a biopsy will show clubbed rete pegs if positive for psoriasis.
- Psoriasis is a papulosquamous disease with variable morphology, distribution, severity, and course.
- It is characterized by scaling papules and plaques.
- Koebner phenomenon: Appearance of new psoriatic lesions at the site of skin injury.
- Woronoff’s ring: Ring of peripheral blanching skin around a psoriatic plaque.
- Auspitz’s sign: Small bleeding points seen upon disruption of a psoriatic scale.
Scalp
Extremities
Trunk
Face
Nail Psoriasis
Inverse Psoriasis
HEENT
- Scalp psoriasis may cause raised, reddish, often scaly patches.
- Ophthalmoscopic exam in psoriasis may show uveitis, more frequently in patients with arthropathy or pustular psoriasis.[3]
- Sensorineural hearing loss associated with psoriatic arthritis.
- Rinne test may be negative (abnormal).
- Weber test may show a quieter sound in the ear with the sensorineuronal hearing loss.
Neck
- Cervical Lymphadenopathy
Lungs
- Psoriasis has been known to be associated with COPD.[4]
- Exapnded/barrel shaped chest because of COPD.
- Bilateral decresed breath sounds.
- Bilateral wheezes.
- Egophony absent.
- Reduced tactile fremitus.
Heart
- The risk of arterial and venous vascular diseases (eg, myocardial infarction, thrombophlebitis, pulmonary embolization) is higher in sever psoriasis involving multiple areas of the body.[5]
- There may be a chance of getting high output cardiac failure to to erytheroderma.[5]
Abdomen
- No abdominal distention.
- No abdominal tenderness.
- No Hepatomegaly / splenomegaly / hepatosplenomegaly.
