Acral peeling as the sole skin manifestation of COVID-19 in children

Membranous desquamation of the hand in a 7-year-old boy with mild COVID-19

A 7-year-old Japanese boy was diagnosed with coronavirus disease 2019. He developed intermittent fever and headache, and the symptoms improved by Day 3. However, he developed membranous desquamation without erythema or swelling on the right hand on Day 4, which improved without treatment.

Epidemiology and clinical evolution of non-multisystem inflammatory syndrome (MIS-C) dermatological lesions in pediatric patients affected by SARS-CoV-2 infection: A systematic review of the literature

COVID-19 can present with a range of skin manifestations, some of which specific of the pediatric age. The aim of this systematic literature review was to determine the type, prevalence, time of onset, and evolution of cutaneous manifestations associated with COVID-19 in newborns, children, and adolescents, after excluding multisystem inflammatory syndrome in children (MIS-C). PubMed, Tripdatabase, ClinicalTrials, and Cochrane Library databases were searched using an ad hoc string for case reports/series and observational studies, published between December 2019 and February 2022. Study quality was assessed using the STROBE and CARE tools. Seventy-three (49 case reports/series and 24 studies) out of 26,545 identified articles were included in the analysis. Dermatological lesions were highly heterogeneous for clinical presentation, time of onset, and association with other COVID-19 manifestations. Overall, they mainly affected the acral portions, and typically presented a favorable outcome. Pseudo-chilblains were the most common.

CONCLUSIONS

Mucocutaneous manifestations could be the only/predominant and early manifestation of COVID-19 that could precede other more severe manifestations by days or weeks. Therefore, physicians of all disciplines should be familiar with them.

WHAT IS KNOWN

• A variety of cutaneous manifestations have been reported in association with COVID-19. • Urticaria, maculopapular, or vesicular rashes can occur at any age, while chilblains and erythema multiforme are more common in children and young patients.

WHAT IS NEW

• Skin lesions related to SARS-CoV-2 infection often show a peculiar acral distribution. • Mucocutaneous lesions of various type may be the only/predominant manifestation of COVID-19; they could present in paucisymptomatic and severely ill patients and occur at different stages of the disease.

Acral manifestations associated with infection

Acral lesions are well-known physical findings in various infectious disorders. Although they are often overlooked, they can be the key to the diagnosis of the underlying disease. Considering this, we present an overview of various infectious causes of acral lesions in childhood. In addition, we discuss their characteristic presentation, evolution, and appropriate treatment. To our knowledge, this is the first review covering viral, bacterial and mycotic causes.

Top 10 acral skin manifestations associated with COVID-19: A scoping review

COVID‐19‐associated cutaneous manifestations are one of the most important and relatively common extra‐respiratory presentations of SARS‐COV‐2 infection. The exact identification and classification of these lesions can facilitate the accurate diagnosis and treatment. There are several case reports and small case series which describe cutaneous lesions in hands and feet. Currently, there is no scoping review about acral skin manifestations associated with COVID‐19. This paper covers the COVID‐related acral skin manifestations in 10 entities including acral papulo‐vesicular eruption, acral urticarial lesion, acral non‐inflammatory purpura and necrosis, acro‐ischemia associated COVID‐19, acral vasculitis, chilblain‐like lesion (COVID Toe), acral erythema multiform (EM) like lesion, hand and foot skin lesions associated with multisystem inflammatory syndrome in children (MISC), acral peeling conditions and red half‐moon nail sign. Future studies should focus on exact investigation of etiologies of these lesions including role of immune senescence, environment, gender, immunogenetics and relation of these lesion with major organ involvements.

Dermatological Manifestations Associated with COVID-19 Infection

The severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) causing the 2019 coronavirus disease (COVID-19) has infected millions in recent years and is a major public health concern. Various cutaneous manifestations of the COVID-19 disease have been identified. Skin is a mirror to internal disease and can be the presenting sign of COVID-19 disease. Several cutaneous manifestations can indicate severe COVID-19 disease. In the present scenario, physicians should know the various cutaneous manifestations of COVID-19 disease for early diagnosis and proper management of the disease.
