UNLABELLED: Pyoderma gangrenosum (PG) is a rare, poorly understood skin disease that occurs in all age groups. Less than 0.4% of patients are infants and represent a diagnostic challenge as early lesions may resemble other skin disorders. Here we report for the first time three siblings affected with PG all presenting during infancy. Unlike the older age group, the ulcers spared the legs but involved the buttocks, thighs and perianal area in all the infants. CONCLUSION: This is the first reported family with PG affecting three siblings suggesting autosomal recessive inheritance. The diagnosis may be more difficult in infants due to absence of underlying associated disorders and the tendency of the lesions to appear in areas where infants frequently have other dermatoses. PG characteristically involves the buttocks, thighs and perianal area and spares the legs.
