Subcorneal pustular dermatosis (SCPD) also known as neutrophilic dermatosis is characterized by superficial pustular lesions.1 It was first described by Ian Sneddon and Darrell Wilkinson in 1956.1,2 The primary lesions are pea-sized pustules classically described as half clear, half pustular, flaccid blisters. The exact cause of SCPD is not yet known. It is a rare, chronic, relapsing pustular disorder with a predilection for flexural aspects of the limbs, trunk, and intertriginous areas. Usually it spares the face, palms, soles and mucous membrane. This condition is frequently seen in adults, especially in women, in the age group 40-50 years.3 In rare cases, unusual involvement of the face, palms, and soles has been described.4 Dapsone is the treatment of choice for SCPD. Others includes retinoids, colchicine, phototherapy with psoralen, ultraviolet A (PUVA), broad or narrow band UVB, corticosteroids and cyclosporine. The anecdotal use of tetracycline, minocycline, vitamin E, tacalcitol, infliximab, ketoconazole, mizoribine, mebhydrolin and mycophenolate mofetil.4 However this disease can occur rarely during the childhood. Only few pediatric SCPD are described in literature.5,6 We report a case of SCPD in a 3-year-old child which mimicked pustular psoriasis and was treated with topical dapsone showing good results.
