Allergy to muscle relaxants is a known entity. Several drugs can be incriminating for both major and minor allergic reactions in the perioperative setting. These reactions are either of immunologic origin (IgE mediated anaphylaxis) or related to direct stimulation of histamine release (anaphylactoid reactions). Atracurium besylate, an intermediate acting non-depolarizing neuromuscular blocking agent (NMBA), belonging to the tetrahydroisoquinolinium class, is associated with allergic reactions, including severe anaphylaxis. We present a unique mechanism (the tourniquet effect of a blood pressure cuff) for local cutaneous allergy to intravenous atracurium in a breast cancer patient, which is further reinforced by postoperative allergologic work-up. Eternal vigilance and high degree of suspicion are advocated to diagnose and manage such reactions.
