A Swollen Red Leg: Sweet’s Syndrome

Abstract

Neutrophillic dermatoses comprise a range of conditions where the hallmark is histologic infiltrate of neutrophils. Ranging from skin disorders such as acute generalised exanthematous pustulosis or subcorneal pustulosis (Sneddon Wilkinson) which affect the epidermis, the neutrophilic infiltrate can affect the dermal portion such as in Neutrophillic urticaria, Sweet’s syndrome, or eccrine neutrophilic hidradenitis, or it can affect both epidermis and dermis such as in pyoderma gangrenosum. Many times the diagnosis of a neutrophilic dermatosis poses a challenge as the main differential are infectious diseases and a high degree of suspicion needed. Generally, the diagnosis is reached with clinical and dermatopathology correlation. We present the case of an 87-year-old woman with swollen red leg in whom the diagnosis posed a challenge
