Open Method for Surgical Removal of Modeling Substance in a Patient with Iatrogenic Gluteal Allogenosis

Introduction: Surgical removal of modeling substances is the treatment of choice in iatrogenic allogenosis. This is a disease caused by the injection of substances misnamed “biopolymers” with high antigenicity and low histocompatibility. Symptoms can be local or general, leading to a systemic inflammatory autoimmune syndrome induced by adjuvants. Method: A patient operated by open method for the surgical extraction of allogenic substances in the gluteal region is described. Results: A 46-year-old female patient with a history of injection of more than 1000 ml of liquid silicone in both buttocks and face 11 years ago is presented. Two years later, she presented erythema, increased consistency, pruritus, and hyperemia, associated with general symptoms that limited her daily activities. She was diagnosed with an adjuvant-induced systemic inflammatory autoimmune syndrome and was admitted for surgical removal of the causative agent. Surgical extraction of alloplastic material in the gluteal region was performed for the first time in Cuba without local postoperative complications. Conclusion: Surgical treatment by the open biopolymer extraction method is deforming, but it is the only solution to improve the symptoms of iatrogenic allogenosis.
