Recognition and timely adequate treatment of erythema multiforme remain a major challenge. In this review, current diagnostic guidelines, potential pitfalls, and modern/novel treatment options are summarized with the aim to help clinicians with diagnostic and therapeutic decision-making. The diagnosis of erythema multiforme, that has an acute, self-limiting course, is based on its typical clinical picture of targetoid erythematous lesions with predominant acral localization as well as histological findings.

New all-oral direct-acting antivirals (DAA) have changed the hepatitis C virus (HCV) treatment landscape. Given that dermatologists frequently encounter HCV-infected patients, knowledge of the current treatment options and their utility in treating HCV-associated dermatologic disorders is important. In addition to highlighting the new treatment options, we review four classically HCV-associated dermatologic disorders - mixed cryoglobulinaemia (MC), lichen planus (LP), porphyria cutanea tarda (PCT) and necrolytic acral erythema (NAE) - and examine the role for all-oral direct-acting antiviral (DAA) regimens in their treatment.

In addition to its contributing role in the development of chronic liver diseases, chronic hepatitis C virus (HCV) infection is associated with extrahepatic manifestations, particularly, cutaneous-based disorders including those with pruritus as a symptom. Pruritus is frequently associated with the development of chronic liver diseases such as cholestasis and chronic viral infection, and the accumulation of bile acids in patients' sera and tissues as a consequence of liver damage is considered the main cause of pruritus. In addition to their role in dietary lipid absorption, bile acids can trigger the activation of specific receptors, such as the G protein-coupled bile acid receptor (GPBA/ TGR5). Read More

Background: Chronic hepatitis C (CHC) infection causes a wide range of immune mediated hepatic and extrahepatic manifestations. Cutaneous manifestations constitute a major portion of the latter group. Host immune response to the virus - particularly regulatory T lymphocytes - is important in determining the outcome of the infection and the possibility of extrahepatic manifestations. Read More

Vasculitis is a remarkable presentation of the extrahepatic manifestations of HCV. According to the presence or absence of cryoglobulins it is subdivided into two main types: cryoglobulinemic vasculitis and non cryoglobulinemic vasculitis based on the attribution of vasculitis to serum cryoglobulins as a pathogenic factor. The attribution of cryoglobulinemia to HCV represents a success story in the history of immunology, microbiology, and clinical medicine. Read More

Porphyrias are a group of metabolic disorders, which result from a specific abnormality in one of the eight enzymes of the heme biosynthetic pathway. These have been subdivided based on the predominant site of enzyme defect into hepatic and erythropoietic types and based on clinical presentation into acute neurovisceral and cutaneous blistering porphyrias. This review focuses on hepatic porphyrias, which include acute intermittent porphyria (AIP), variegate porphyria (VP), hereditary coproporphyria (HCP), aminolevulinic acid dehydratase deficiency porphyria (ADP), and porphyria cutanea tarda (PCT).

The association of chronic hepatitis C virus (HCV) infection with a wide spectrum of cutaneous manifestations has been widely reported in the literature, with varying strength of epidemiological association. Skin diseases which are certainly related with chronic HCV infection due to a strong epidemiological and pathogenetic association are mixed cryoglobulinemia, lichen planus and porphyria cutanea tarda. Chronic pruritus and necrolytic acral erythema are conditions that may share a possible association with HCV infection, while several immune-mediated inflammatory skin conditions, such as psoriasis, chronic urticaria and vitiligo, have been only anecdotally reported in the setting of chronic HCV infection.

Serum sickness and polyarteritis nodosa are predominantly associated with hepatitis B infection, whereas mixed cryoglobulinemia associated vasculitis and porphyria cutanea tarda are more frequently seen in hepatitis C infection.

Objective: Cryoglobulinemic vasculitis (CV) involving small- and medium-sized vessels is very frequently associated with hepatitis C virus and may be responsible for multiple organ involvement and skin ulcers (SU). Skin ulcers are often non-healing cutaneous lesions, possibly complicated by local infection and gangrene; they may severely affect the patients׳ quality of life and the overall prognosis. Therefore, the treatment of cryoglobulinemic SU is particularly challenging in the clinical practice. Read More

During the course of chronic hepatitis C virus (HCV) infection, various extrahepatic manifestations of autoimmune disorders may occur, including arthralgia/arthritis, sicca complex, purpura, cutaneous ulcer, and thyroid dysfunction. In addition, the prevalence of circulating autoantibodies is high among patients with HCV infection. Commonly detected autoantibodies in HCV-infected patients include rheumatoid factor, antinuclear antibody, anti-SSA/anti-SSB antibody, cryoglobulin, antineutrophil cytoplasmic antibody, anti-smooth muscle antibody, anti-liver and anti-thyroid autoantibodies.
