Hypersensitivity reaction to hyaluronic acid dermal filler concomitant with coronavirus infection - case report

The incidence of hypersensitivity reactions to dermal fillers with hyaluronic acid is between 0.3 and 4.5% being mediated by T lymphocyte. Influenza-like illnesses can trigger immunological reactions at the site of the filler. The authors report a case of a patient who presented a hypersensitivity reaction to the filler concomitant with a SARS-COV-2 infection. With the large-scale growth of procedures with fillers, there has been an increase in allergic reactions, making their identification essential for adequate treatment, minimizing the deleterious consequences to the patient.
