Cutaneous manifestations present in patients with COVID-19: a systematic review.

Abstract

Introduction: The first retrospective study conducted at the site where the COVID-19 pandemic started does not report cutaneous manifestations in patients. Subsequently, there was a report of 0.2% then 4.9% and 20.4% of dermatological conditions present in patients infected by the disease, however, they were always considered non-specific and unusual, so it is notorious that dermatology was not studied in infected patients. Objective: to analyze the cutaneous manifestations occurring in patients infected by COVID-19 by means of a systematic review Methods: this research details the cutaneous manifestations of the first studies carried out since 2020 by means of selection by inclusion and exclusion criteria. Results: they depend on several factors and it is possible to find pseudo-scabies type lesions, vasculo-purpuric lesions, urticaria, rash, maculopapular, acral lesions with erythema, livedo and necrosis, however, there is a key factor and it is that many times cutaneous manifestations could be confused with adverse reactions caused by drugs used to combat the disease. In spite of the results obtained in this review, the same determinants cannot be defined in children, since there are no reports of such manifestations that offer important data; there are only reports of erythematous maculopapular eczema, non-pruritic on neck and trunk, and urticaria. Conclusions: when having a first contact with a patient infected by COVID-19, a complete and integral approach of the patient should be carried out since there are numerous manifestations that guide the diagnosis and dermatology should not be overlooked in an infected patient.
