Maculopapular skin eruptions associated with Covid-19: A systematic review

In this systematic review, we anticipated in summarizing clinical features, histopathological hallmarks, and possible pathology behind the maculopapular skin eruptions occurring in Covid-19 patients. A literature search was executed using MEDLINE/PubMed and Embase databases for articles published till 20 November 2020. All eligible articles including observational studies, case reports, and case series reporting the maculopapular skin lesion in Covid-19 patients were included. Data were obtained for 354 Covid-19 patients presenting with maculopapular lesions from 40 studies. The mean age of these patients was 53 years, and with 42% of them being male. These maculopapular lesions differed considerably in terms of distribution and appearance, ranging from diffuse erythematous maculopapular lesions to scattered erythematous macules coalescing into papules to maculopapular lesions in plaques. The mean duration of the lesion was 8 days. These lesions were frequently localized on trunks and extremities. Superficial perivascular dermatitis with lymphocytic infiltrate was a histopathological hallmark of these lesions. As these skin lesions may have a possible association with diagnosis, management, prognosis, and severity of the disease, all health practitioners need to be well acquainted with these Covid-19 skin lesions. Also, in the middle of this worldwide pandemic, early identification of this eruption may help manage this infection's further spread.
