1/3. psoriasis herpeticum: three cases of Kaposi's varicelliform eruption in psoriasis.BACKGROUND: Kaposi's varicelliform eruption (KVE), first described in 1887 by Moritz Kaposi, refers to a disseminated cutaneous infection with herpesvirus type 1 or 2, vaccinia virus, or coxsackievirus A16 in a patient with another underlying dermatosis. When herpesvirus type 1 or 2 is the pathogenic virus, the term "eczema herpeticum" is used, independent of the underlying dermatologic diagnosis that preceded the eruption. KVE is most often seen in patients with underlying atopic dermatitis, but has also been seen in association with other papulosquamous and acantholytic disorders. However, eczema herpeticum rarely occurs in patients with psoriasis. OBSERVATIONS: We present the clinical and laboratory findings of three patients in whom KVE developed during inpatient hospitalization for a psoriatic flare. These patients each had comorbidities that may have increased susceptibility to KVE. CONCLUSIONS: KVE may rarely occur in patients with psoriasis. Erythroderma, systemic sepsis, therapy with immunosuppressant drugs, such as methotrexate and systemic steroids, and therapy with systemic retinoids may possibly increase susceptibility to KVE.- - - - - - - - - - ranking = 1keywords = herpesvirus (Clic here for more details about this article) |
2/3. eczema herpeticum. Treatment with methylene blue and light.kaposi varicelliform eruption due to herpes simplex virus (eczema herpeticum) is a serious disease in infants, with occasional fatal outcome. Photoinactivation therapy consisting of local application of methylene blue followed by light exposure resulted in rapid improvement both clinically and virologically. methylene blue, at a concentration of 10(-5)M was found to be viricidal to herpesvirus in the light but not in the dark.- - - - - - - - - - ranking = 0.5keywords = herpesvirus (Clic here for more details about this article) |
3/3. eczema herpeticum caused by herpesvirus type 2. A case in a patient with darier disease.This, to our knowledge, is the first documented report of eczema herpeticum due to infection with herpesvirus hominis type 2. The virus was isolated from a patient with known darier disease who developed kaposi varicelliform eruption. Recent increases in the incidence of infection with type 2 herpes simplex as well as the high frequency of recurrence with this virus make this infection of potential significance in patients with preexisting cutaneous disease.- - - - - - - - - - ranking = 2.5keywords = herpesvirus (Clic here for more details about this article) |
