Local cutaneous reaction induced by subcutaneous interleukin-2 and interferon alpha-2a immunotherapy following ABMT.

Immunotherapy using subcutaneous injections of recombinant interleukin-2 (IL-2) and recombinant interferon alpha-2a (IFN-alpha) for advanced hematologic and solid tumors is rapidly developing. We report five patients with Hodgkin's and non-Hodgkin's lymphoma who developed a local cutaneous reaction consisting of inflammatory painful nodules with a central multiloculated vesicle at the site of sc injections of IL-2 and IFN-alpha immunotherapy following ABMT. This is the first report of a local cutaneous adverse reaction induced by IL-2 and IFN-alpha immunotherapy following ABMT.
