Erythema multiforme: histological features and DermNet N

Recurrent erythema multiforme often is secondary to HSV-1 and -2 reactivation, although the HSV may be clinically silent.10 In a study involving 63 patients with erythema multiforme, HSV DNA was detected (by polymerase chain reaction in skin biopsy specimens) in 60 percent of patients with clinically diagnosed recurrent herpes-associated erythema multiforme and in 50 percent of patients with recurrent idiopathic erythema multiforme (defined as erythema multiforme with no clinical history of HSV infection or drug ingestion).19 In another study, researchers determined the genotype of HSV in cutaneous lesions of patients with herpes-associated erythema multiforme; 66.7 percent of cases were attributed to HSV-1, 27.8 percent to HSV-2, and 5.6 percent to HSV-1 and -2 coinfection.27 These results ref lect the seroprevalence of HSV-1 and -2 in the United States.28 However, most patients with HSV infection do not develop erythema multiforme. In addition, patients with herpes-associated erythema multiforme may have clinically apparent HSV reactivation without an episode of erythema multiforme or erythema multiforme without clinically apparent HSV infection.10,29Erythema multiforme is an acute, self-limited, and sometimes recurring skin condition considered to be a hypersensitivity reaction associated with certain infections and medications (Table 11,2).2,3 Previously, the condition was thought to be part of a clinical spectrum of disease that included erythema minor, erythema major (often equated with Stevens-Johnson syndrome [SJS]), and toxic epidermal necrolysis (TEN), with erythema minor being the most mild and TEN the most severe.4  An often-cited study from 1993 proposed a useful clinical classification of erythema multiforme, SJS, and TEN based on the pattern of individual skin lesions and the estimation of body surface area with detachment of the epidermis (i.e., blisters, denuded areas, or erosions) at the worst stage of the disease (Table 21,2,5,6).5 Although SJS and TEN may represent the same process with differing severity,6 erythema multiforme, with its minimal mucous membrane involvement and less than 10 percent epidermal detachment, now is accepted as a distinct condition. The remainder of this article will focus on erythema multiforme.NewsletterWhat to know about erythema multiformeMedically reviewed by Cynthia Cobb, DNP, APRN on November 26, 2018 — Written by Adrienne StinsonOverviewCausesDiagnosisTreatmentOutlookErythema multiforme is a skin immune reaction that an infection or medication can trigger. Its name combines the Latin “erythema” (redness), “multi” (many), and “forme” (shapes) and describes the main symptom, which is a rash on the body where each mark resembles a bullseye.

This hypersensitivity is mainly due to drugs and infections. It is clinically characterized by macular, papular and urticarial lesions. Target lesions are characteristic of this disease.Individuals with persistent (chronic) erythema multiforme will often have a lesion form at an injury site, e.g. a minor scratch or abrasion, within a week. Irritation or even pressure from clothing will cause the erythema sore to continue to expand along its margins for weeks or months, long after the original sore at the center heals.[citation needed]

If mycoplasma pneumonia is responsible for the rash, doctors may prescribe antibiotics such as a macrolide, tetracycline, or azithromycin.Recurrent erythema multiforme may be treated with continuous oral acyclovir (400 mg two times per day) even if HSV is not an obvious precipitating factor.6 Oral acyclovir has been shown to be effective in the suppression of recurrent erythema multiforme in a double-blind placebo-controlled trial.35 Valacyclovir (Valtrex; 500 to 1,000 mg per day) and famciclovir (Famvir; 125 to 250 mg per day) have greater oral bioavailability than acyclovir and may be tried in patients who have no response to acyclovir.4,36 The dosage of the antiviral may be reduced once the patient is recurrence free for four months, and eventually the drug may be discontinued. The dosage must be adjusted for patients with renal insufficiency.

The pathogenesis of herpes-associated erythema multiforme has been well studied and is consistent with a delayed-type hypersensitivity reaction.3,30 The disease begins with the transport of viral DNA fragments to distant skin sites by peripheral blood mononuclear cells. HSV genes within DNA fragments are expressed on keratinocytes, leading to the recruitment of HSV-specific CD4+ TH1 cells (helper T cells involved in cell-mediated immunity). The CD4+ cells respond to viral antigens with production of interferon-γ, initiating an inflammatory cascade.3 Drug-associated erythema multiforme lesions test positive for tumor necrosis factor α and not interferon-γ as in herpes-associated erythema multiforme lesions, suggesting a varying mechanism.30 CONCLUSIONS Erythema multiforme is a rare skin condition, easily diagnosed based on its characteristic clinical Erythema multiforme--etiopathogenic, clinical and therapeutic aspects

Categories: Pathology, Reaction to external agent The differential diagnosis (Table 330,32) of early erythema multiforme includes drug eruption, polymorphic light eruption, urticaria, urticarial vasculitis, viral exanthems, and other hypersensitivity reactions.32 Because erythema multiforme often resembles urticaria at the onset of the eruption, it is important to distinguish the clinical features. The individual lesions of erythema multiforme in typical cases are present and fixed for at least one week, and some evolve into target lesions.33 In contrast, the individual lesions of urticaria exist at the same site for less than 24 hours,8 and the centers of the lesions appear normal or as red as the borders.6 Target lesions with dusky or purpuric centers may resemble pityriasis rosea, lupus erythematosus, vasculitis, or figurate erythema.32 When bullous lesions are present, erythema multiforme must be distinguished from the autoimmune bullous diseases.31
