Photopheresis, also called extracorporeal photopheresis, is a form of apheresis and photodynamic therapy in which blood is separated to isolate the buffy coat of white cells and platelets, chemically treated with the light-sensitizing compound 8-methoxypsoralen, exposed to ultraviolet A light, and then returned to the patient; the treated cells appear to induce a cytotoxic effect on T-cell formation once returned. Introduced in a 1987 New England Journal of Medicine publication, it is now a standard United States Food and Drug Administration therapy for cutaneous T-cell lymphoma, and evidence, though largely observational, suggests it may also help treat graft-versus-host disease and epidermolysis bullosa acquisita when other treatments have failed.
