Gianotti-Crosti Syndrome in a Child with Recent Covid-19 Infection: A Case Report

Gianotti-Crosti Syndrome is a rare skin disease affecting children at the first years of age. The condition is clinically featured by blisters on the skin of the legs, buttocks and arms. A history of viral infection preceding the disease was reported for many cases. A 12-month-old boy, free of any medical illnesses, was presented with a history of acute-onset rash for five days prior to presentation that was preceded by a history of fever for two days then subsided. The rashes appeared initially on his buttocks, then spread to his upper and lower extremities and trunk. The child had fever, sore throat and coryza symptoms with lethargy. A polymerase chain reaction (PCR) swab was taken to test for SARS-CoV-2, which was positive two weeks before rash onset. All symptoms resolved in 1 week with supportive therapy and the current rashes appeared two weeks later in the patient. Gianotti–Crosti syndrome may follow the active phase of infection for some cases. It should not be misdiagnosed with dermatological simple eruptive disorders. The clinical features for covid-19 associated infection are typical for the well-known clinical picture of the syndrome. The case was reported to improve clinicians’ awareness and help in better understanding and reporting cutaneous manifestations of COVID-19.
