The most pertinent malignancies, to the plastic surgeon, associated with the degeneration of chronic inflammation include Marjolin's ulcer, breast implant-associated large cell lymphoma, radiation-induced sarcoma, and Kaposi's sarcoma. The cellular and genetic damage incurred by a prolonged inflammatory reaction is controlled by an increasingly understood cytokinetic system. Advances in understanding the chronic inflammatory cascade have yielded new therapeutics and therapeutic targets.
