Diagnóstico e tratamento do impetigo não bolhoso em paciente pediátrico: relato de caso clínico

Abstract

Impetigo is a superficial bacterial skin infection caused by Gram-positive bacteria, common-ly affecting children aged 2 to 5 years, although it can occur at any age. Clinically, impetigo is divided into two forms: bullous and non-bullous. Bullous impetigo is characterized by the formation of large, fragile blisters. In non-bullous impetigo, there is the presence of vesicles and pustules that, after rupture, give rise to meliceric crusts. The clinical case described reports a 12-year-old patient, with a history of psoriasis and atopic dermatitis, who pre-sented with scaly and painful vesicular lesions on the lip and mouth, without a precipitating factor, associated with systemic symptoms. After the symptoms persisted and through the use of laboratory tests that indicated a bacterial infection, the pathology was diagnosed as non-bullous impetigo. The treatment was carried out with the use of antibiotics, photody-namic therapy and hygiene measures, resulting in significant improvement and hospital discharge after five days. Thus, it is noted that the patient presented a typical picture of non-bullous impetigo, with the presence of vesicles and pustules that, after rupture, result-ed in the characteristic “honey-colored crusts” of impetigo. However, there are some diver-gences in the literature, highlighting the severity of the case due to the presence of painful symptoms, systemic symptoms and the most affected age group. The case highlights the importance of differential diagnosis between impetigo and other skin infections, as well as appropriate therapeutic management to avoid complications and promote complete recov-ery.
