DRESS, the maverick among SCARS: A case series-based review of literature

DRESS is a potentially life-threatening severe cutaneous adverse reaction (SCAR). Historically, it was most frequently linked with phenytoin and was initially described as phenytoin hypersensitivity syndrome; however, it was later found to be caused by various other medications, with the commonest been aromatic anticonvulsants, allopurinol and sulfonamides. The severity of this entity is related to systemic involvement, which can result in multiorgan failure and death. The diagnosis of DRESS, especially in the early stages, remains challenging and elusive due to its heterogeneous clinical presentation and the complex course of the disease with different patterns depending on the causal drug. The most important step in the management of DRESS is early diagnosis and immediate cessation of the suspected offending drug along with oral steroids or immunosuppressants to control the disease. We describe the varying presentation and management of six adults with DRESS from a tertiary care hospital, observed over a two-year period with a brief review of the literature.
