ABSTRACT
Sweet's syndrome encompasses a variety of neutrophilic dermatosis characterized by acute onset of erythematous, edematous, painful papules, plaques and nodules associated with systemic symptoms, peripheral blood leukocytosis and histological findings of dense neutrophilic infiltrate. Ten patients were diagnosed during a period of one year. The patient population consisted of 7 females and 3 males with mean age of 47.6 years ranging from 32 to 60 years. An associated disorder was observed in 6 patients which were diabetes, hypothyroidism, hypertension and inflammatory bowel disease. Two cases of pregnancy associated disease were observed. Cutaneous lesions consisted of erythematous plaques or nodules. Lesions were located mainly on the face, neck and upper extremities. All biopsy specimens demonstrated a dermal infiltrate composed predominantly of neutrophils. Seven patients were treated by oral corticosteroids and three by oral dapsone, all for a period of 6 weeks
