Acute febrile neutrophilic dermatosis with genital involvement.

More than 80 cases of acute febrile neutrophilic dermatosis have been published since Sweet in 1964 described the syndrome. Besides skin eruptions, some patients have mucous membrane lesions involving mouth and lips. This report describes a patient with a pustular eruption consistent with Sweet's syndrome, who is believed to be the first with involvement of genital mucosa.
