Children with Gianotti-Crosti syndrome (papular acrodermatitis of childhood) usually present with an acute, symmetric, exanthematous, asymptomatic cutaneous eruption that develops over several days. The eruption typically lasts at least 10 days but can last longer than 6 weeks in more than 50% of patients. Complete resolution typically takes more than 2 months. Recurrences are rare, although a recurrent case associated with influenza virus vaccination has been reported. [37] Pruritus accompanies the eruption in 23% of patients.

Other symptoms related to the primary viral syndrome or underlying bacterial infection may include mild constitutional symptoms such as low-grade fever and malaise, pharyngitis and/or mucosal lesions, or symptoms of an upper respiratory tract infection. When associated with a hepatitis B virus, EBV, or CMV infection, an anicteric acute hepatitis may be present.

A case control study of 29 children with Gianotti-Crosti syndrome from Bologna, Italy demonstrated a higher prevalence of atopic dermatitis in patients versus controls (24.1% vs 6.8%). They also found that patients were more likely than controls to have elevated levels of total and specific immunoglobulin E and a family history of atopy. [38]
