Acute generalized exanthematous pustulosis

Disease definition

A rare toxic dermatosis disease characterized by the rapid development of numerous, nonfollicular, sterile, pinhead-sized pustules on an edematous and erythematous base, predominantly occurring on the trunk, intertriginous and flexural areas, with rare, mostly oral, mucosal involvement. Acute onset of fever (>38°C), peripheral blood leukocytosis, and mild eosinophilia are accompanying features. Systemic involvement, with hepatic, renal or pulmonary dysfunction, occasionally occurs. Histologically reveals characteristic spongiform, subcorneal and/or intraepidermal, pustules, as well as marked edema of the papillary dermis, a perivascularly accentuated, neutrophil-rich inflammatory infiltrate, and intrapustular or intradermal eosinophils.
