Guillain Barre syndrome (GBS) as a complication of hyaluronic acid (HA) exposure is an extremely rare occurrence. We report a case of GBS, acute motor sensory axonal neuropathy (AMSAN) variant, after a HA breast enhancement procedure. A 41-year-old lady underwent a HA breast enhancement procedure from an unlicensed beautician and developed anaphylaxis followed by bilateral breast abscess and neurological deficits involving both motor and sensory components. The AMSAN variant of GBS was diagnosed from the cytoalbuminologic dissociation and nerve conduction study. Her GBS and breast abscess were managed with plasmapheresis and bilateral mastectomy. In this case, GBS was highly suspected to be caused by HA with possible impurities. To the author's knowledge, the association between HA and GBS has not been reported or known, and further studies are required to establish this association. To prevent mortality and morbidity, breast enhancement procedures should be performed by trained professionals with properly vetted products.
