Purpose: To report the case of a patient with multiple food allergies comorbid with multiple chemical sensitivity (MCS) who was misdiagnosed on various occasions, resulting in a negative impact on the patient’s personal and social life. Case Report: We present the case of a 43-year-old Colombian women with multiple food allergies concomitant with MCS. Symptoms started with a mild reaction to insecticides, car exhaust smoke, and perfumes and gradually evolved into a severe reaction to her environ- ment. She also presented recurrent episodes of clinical reactivity to foods and persistent elevated IgE levels, as well as several life-threatening anaphylactic reactions. Alternative and allopathic therapies were applied, but her symptoms persisted. Various diagnoses were made before the definitive diagnosis. Conclusion: MCS is an unusual entity of unknown pathophysiology that can, on rare occasions, coexist with food allergies. Early recognition and multidisciplinary treatment are required as these entities have a major impact on the patient’s quality of life. We present the first Latin American case regarding the association of the two diseases.
