Insights
Necrolytic acral erythema (NAE) is a skin condition uniquely linked to Hepatitis C virus (HCV) infection. Early skin lesion recognition can lead to earlier HCV diagnosis, improving patient outcomes.
Area of Science:
- Dermatology
- Hepatology
- Infectious Diseases
Background:
- Hepatitis C virus (HCV) is a major cause of chronic liver disease in the US.
- Cutaneous manifestations are common in HCV infection, including vasculitis and lichen planus.
- Necrolytic acral erythema (NAE) is a distinct skin condition associated with HCV.
Observation:
- NAE typically presents as chronic, acral, erythematous, and psoriasiform lesions.
- Acute NAE presentations are rare and may have atypical features.
- NAE can precede a formal diagnosis of HCV infection.
Findings:
- NAE is a unique cutaneous marker for HCV infection.
- Dermatologists can suspect HCV based on NAE skin findings.
- Early NAE detection may facilitate earlier HCV diagnosis.
Implications:
- Recognizing NAE can lead to earlier diagnosis and treatment of HCV.
- This highlights the importance of dermatological evaluation in suspected HCV cases.
- Dermatologists play a key role in identifying patients with undiagnosed HCV infection.
Abstract:
Hepatitis C virus (HCV) infection is the most common chronic blood-borne viral infection in the United States. Well-described cutaneous manifestations of HCV infection include polyarteritis nodosa, porphyria cutanea tarda, type II cryoglobulinemia-associated vasculitis, pruritus, erythema nodosum, urticaria and urticarial vasculitis, lichen planus, and erythema multiforme. First described in 1996, necrolytic acral erythema (NAE) is now recognized as a cutaneous acral eruption uniquely associated with HCV infection. Most patients present with chronic, acral, erythematous, and psoriasiform lesions. Acute presentations of NAE are rare and patients may present with atypical clinical features; in these cases, suspicion for HCV infection may be delayed for weeks to months until more classic chronic lesions develop. In many cases, NAE presents before the patient has been diagnosed with HCV infection, which allows dermatologists the unique opportunity to suspect and diagnose HCV infection based on skin findings alone.
