Repurposing Historic Drugs for Neutrophil-Mediated Inflammation in Skin Disorders.

Neutrophil-mediated inflammation is a key feature of immune-mediated chronic skin disorders, but the mechanistic understanding of neutrophil involvement in these conditions remains incomplete. Dapsone, colchicine, and tetracyclines are established drugs within the dermatologist's therapeutic armamentarium that are credited with potent anti-neutrophilic effects. Anti-neutrophilic drugs have established themselves as versatile agents in the treatment of a wide range of dermatological conditions.

While atypical, the development of psoriatic plaques over vascular malformations in children is plausible and should not necessarily prompt clinicians to perform costly or invasive procedures.

HLA-Cw6 Polymorphism in Autoimmune Blistering Diseases.

Autoimmune blistering diseases of the pemphigus and pemphigoid groups are immune-mediated disorders due to circulating pathogenetic autoantibodies. Multiple human leukocyte antigen (HLA) genes have been associated with predisposition to these disorders. HLA-Cw6 is involved in antigen presentation processes and has been linked to psoriasis.
