This is a form of cutaneous polymorphism including red or pinkish lumps, bumps and specific lesions with sympathetic distribution, especially in the extremities of the extremities. Multicellular erythema usually occurs in adults aged 20-40. Although it has been observed in all ages.
Patients may experience itching or burning in the area of the lesions. Individual lesions in the form of multiple red or pink molecules begin with acute margin and then become papular lesions. These papules may gradually be enlarged and become plaques with a diameter of several centimeters. The central portion of the papules or plaques slowly turns to dark red, brown or purpura, and the crevasse or blister appears in the center of the lesions.
In mild form, skin lesions peak within 1-2 weeks and usually disappear within 2-3 weeks, but may persist for up to 6-5 weeks. In severe form, there are many lesions around the skin and the mouth, which sometimes requires hospitalization.
Oral antihistamines and topical steroids can improve symptoms. Also, in people with synchronous or recent infections, the use of HSV, early treatment with an antiviral agent may reduce the number and duration of cutaneous lesions.
Causes of illness
Among the infectious agents that cause the disease are germs and orph, bacteria such as mycoplasma and fungi. Among the drugs, the most common cause of this disease is sulfonamides (cotrimoxazole). Other drugs such as phenytoin, barbiturates, penicillins, and prophylactic drugs can also cause the disease.
In the mild and classical form of multiform multicellular erythema, lesions of the skin are characterized by the target lesion (red-laced lesions with a pale-centered object similar to the shooting target). Often, however, skin lesions also occur in many other forms, such as reddish bumps or juicy, large skin rinds. The name of this disease is due to its various forms, erythema multiforme, which means redness is a polymorphism. The location of these lesions is more at the extremities of the organs (forearms and back of the hands, legs and legs). Pink to red lesions are often associated with moderate pruritus. Definitive diagnosis with biopsy.
