Extra-cutaneous manifestations of neutrophilic dermatosis are exceptio
nal and diverse: they consist of inflammatory infiltrates with neutrop
hil polymorphonuclears, without evidence of infectious agents. Localis
ations to the lung are the most frequently observed. A single observat
ion of spleen involvement has been reported in a case of sneddon-Wilki
nson's disease. Herein we report the case of an aseptic splenic absces
s during the course of a Sweet's syndrome.
