“…Acute post-infectious pityriasis rubra pilaris is a variant of the juvenile form of pityriasis rubra pilaris (Griffiths type III) characterized by the absence of family history, acute course related to a previous febrile episode and good prognosis 12 . Clinically it may mimic other superantigenmediated diseases, such as scarlatiniform rashes or staphylococcal scald syndrome; however, its histology and treatment are different 13 . The exact etiology and pathogenesis of pityriasis rubra pilaris are still unknown.…”

Case description: 32-month-old boy, IgG positive for SARS-CoV-2, presented to the emergency department with dermatologic lesions. Clinical findings: Four days before admission, he presented skin eruptions with redness and pruritus on hands and feet. Generalized papular erythema was evidenced, upper extremities with diffuse erythematosquamous plaques, palmoplantar keratoderma, so he was evaluated by a dermatologist who diagnosed pityriasis rubra pilaris. Treatment and outcome: rehydrating cream, cetirizine 0.5 mg/kg/day every two days, and prednisolone 2 mg/kg/day in the morning. He was discharged after 14 days, the patient presented clinical improvement, but the erythematous lesion persisted on the trunk and extremities. In the evaluation, after three months, the patient did not show the described lesions, evidencing an improvement and clinical resolution of the dermatological problems. Clinical relevance: We report a patient with pityriasis rubra piloris associated with a post-infection by SARS-CoV-2 that had not been described before.

“…Clinical features may resemble other superantigen-mediated diseases, such as scarlatiniform rash, staphylococcal scalded skin syndrome, toxic shock syndrome or Kawasaki disease. 5 In conclusion, the association between COVID-19 and PRP may be coincidental, nevertheless viral infections have been proposed to be a triggering event for PRP pathogenesis. Further research is needed to confirm the correlation between SARS-CoV-2 infection and PRP.…”

“…4 This form is a variant of type III PRP characterized by: (I) no family history, (II) occurred after the first year of life, (III) an acute course preceded by symptoms of an infection, (IV) no clinical or laboratory abnormalities except those due to the initial infection, (V) scarlatiniform erythema followed by follicular papules with appearance of classical juvenile PRP weeks later and (VI) good prognosis but resolution may be slow, and no tendency toward recurrence. 5,6 In the literature, there are a few reports describing connections between PRP and both bacterial and viral infections. Clinical features may resemble other superantigen-mediated diseases, such as scarlatiniform rash, staphylococcal scalded skin syndrome, toxic shock syndrome or Kawasaki disease.…”

“…There were limited data regarding PCL and COVID-19. The United States CL Consortium and the EORTC CLTF established some general recommendations for the treatment of PCLs during the COVID-19 pandemic 5,6 while some authors suggested that PCL does not increase the risk of SARS-CoV-2. 7 As far as we know, this study is the first to describe the incidence and severity of COVID-19 among PCL patients.…”

Pityriasis rubra pilaris (PRP) is an uncommon papulosquamous dermatosis characterized by follicular, erythematous, hyperkeratotic papules coalescing to salmon-coloured plaques with islands of sparing. The disease tends to be self-limited and resolves spontaneously after a few years. In some cases, the disease is persistent. However, recurrence of this disease has rarely been described. An 8-year-old male was diagnosed with type III (classic juvenile) PRP. He was treated with acitretin, and his skin was clear after 6 months. He remained disease free for 6 years. At 14 years old, he was diagnosed again with type III PRP. His cutaneous manifestations were highly similar to his initial presentation. He was treated with acitretin and methotrexate concurrently and achieved skin clearance. Recurrence of type III PRP is possible although rarely described in the literature. Acitretin ± methotrexate therapy is effective at achieving skin clearance.
