This paper describes a lip filling technique that administers hyaluronic acid using microcannulas. This technique considerably reduces the number of punctures compared to the conventional method, which uses needles. In addition, the microcannula’s blunt tip reduces the risks of intravascular injection of the substance and of disrupting key structures such as vessels and nerves. The results obtained by the authors confirm the less frequent occurrence of adverse effects and a high degree of physician and patient satisfaction.

Persistent Intermittent Delayed Swelling (PIDS) due to hyaluronic acid implantation is an immune-mediated inflammatory reaction resulting from immunogenic phenomena to the filler itself, and its ability to retain water, thus configuring local edema. Viral or bacterial infections can trigger the condition. As with many infectious diseases, COVID-19 may have several signs and symptoms on the skin that are not yet fully understood, but many associated skin manifestations have already been described. Through this case report, we report the novelty of an ETIP-type reaction triggered by SARS-CoV-2 infection.

A Covid-19, doença causadora de síndrome gripal e insuficiência respiratória aguda, vem demonstrando provocar danos a diversos outros órgãos e sistemas. Várias manifestações dermatológicas já foram descritas. Relatamos um quadro de alopecia areata (AA) desencadeada possivelmente pela Covid-19 em paciente que, apesar de ter seu RT-PCR para SARS-CoV-2 negativo, apresentou IgM reagente e sintomatologia clássica relacionada à doença. Acreditamos que a Covid-19 possa ter desencadeado resposta imunológica autoimune, com a consequente produção de interferons, que levou ao quadro de AA.

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.
