Skin, mucosa and nail findings in hospitalized pediatric patients with Coronavirus disease-2019 (COVID-19)()

BACKGROUND: Cutaneous manifestations of Coronavirus Disease-2019 (COVID-19) disease have not yet been fully described in hospitalized pediatric patients. OBJECTIVES: This prospective study aims to demonstrate the skin, mucosal, and nail findings of hospitalized children with COVID-19. METHODS: The authors included hospitalized pediatric patients. Two dermatologists examined skin, hair, nails, and mucosa. Patients with drug eruptions were excluded with an anamnesis, clinical and laboratory test results. RESULTS: Out of 46 enlisted patients, 19 (41,3%) patients displayed skin, mucosal or nail findings. Skin findings were seen on 14 (30.4%) patients. Ten (22%) patients presented skin findings matching described patterns. Half of the patients with patterned rashes had confluent erythematous/maculopapular/morbilliform rashes. Eleven out of 46 (23.9%) patients developed periorbital erythema and edema. Ten (22%) patients had at least one oral mucosal finding. One telogen effluvium, one blue nail, and one flag sign on nails were noticed. Nine (19.5%) patients out of 46 had developed MIS-C. MIS-C patients had mucocutaneous manifestations except one (88.8%). STUDY LIMITATIONS: The authors have detected a higher rate of mucocutaneous manifestations compared to out-patients with mild COVID-19 because the study is based on hospitalized patients only. CONCLUSIONS: Pediatric COVID-19 patients are more susceptible to developing mucocutaneous manifestations compared to adults. The authors propose COVID-19 should be acknowledged as one of the viral exanthem rashes of childhood. The authors noticed that the most common findings were periorbital erythema and edema. The confluent erythematous/maculopapular/morbilliform rashes appear to be the most common patterns associated with severe COVID-19.
