Background: A variety of skin manifestations have been associated with COVID-19 infection. Acral lesions on hands and feet, closely resembling chilblains, have been reported in association with COVID-19, which are nonspecific. These acro-ischemic painful lesions have been described mainly in asymptomatic and mildly symptomatic pediatric COVID-19 positive patients, without a precise pathogenetic mechanism.COVID-19-induced chilblains may portend an indolent course and a good outcome. In young patients, the IFN-1 response induces microangiopathic changes and produces a chilblain lupus erythematosus-like eruption with vasculitic neuropathic pain features. Objectives: This paper presented a case series of pediatric patients with COVID-19-related skin lesions and neuropathic-like pain. Methods: Clinical outcomes were collected from 11 patients diagnosed with painful erythematous skin lesions with neuropathic-like pain and positive IgG for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Results: It is a mildly symptomatic condition not related to severe pain rates, and it is treated with paracetamol due to the transitory nature of the problem, which provides good results. Conclusions: A particular point of interest is skin lesion manifestation as a further indirect sign of SARS-CoV-2 infection. Due to the initial manifestation of chilblains in pauci-symptomatic pediatric patients, they need to be immediately tested and isolated. Chilblains can be considered a clinical clue to suspect SARS-CoV-2 infection and help in early diagnosis, patient triage, and infection control.
Background: Cutaneous manifestation of COVID 19 in children has not yet been reviewed systematically and hence this review gives a future direction to the clinicians to be vigilant for skin presentations during such pandemic. Methodology: The review was done as per the guidelines of PRISMA and literature search was done on PubMed database using keywords as COVID-19, children and skin in different combinations. Articles published in English with cases of age 1 month to 18 years were eligible. The outcome included varied aspects of cutaneous and COVID-19 infection. The review protocol was not registered. Results: Of 51 publications identi ed, 13 studies containing 149 children met the eligibility criteria. Acrally located erythematous maculopapular lesion was the most common nding in 138 children. Erythema multiforme, varicella like exanthem and Kawasaki disease like presentations were reported in the rest of the cases. The duration of the skin lesion was 1-2 weeks in 43%. Skin biopsy done in 18 cases revealed super cial & deep perivascular and peri-eccrine lymphocytic in ltrate & lymphocytic vasculitis. RT-PCR was positive in 13.8% cases. Serological markers for HSV, parvovirus B19 analyzed across various studies, were found negative, except for mycoplasma pneumoniae in 2 of 20 cases tested. Discussion: Clinicopathologic analysis established chilblains like lesion in 43% cases with no con rmed etiology like cold exposure, autoimmune dysfunction, drug reaction, or viral infection. The usual cephalocaudal spread of a viral exanthem was also missing. However, a low number of discussed cases was a limitation of the study. Conclusion: In the absence of any con rmed etiology for such cutaneous manifestations, the possibility of COVID-19 should be explored and evaluated thoroughly during such pandemic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
