No racial predilection is apparent for Gianotti-Crosti syndrome.


In children, males and females are equally affected. Reported cases in adults have been seen almost exclusively in females.


The onset of the eruption typically occurs in children aged 3 months to 15 years, with an average age of 2 years and a peak incidence at 1-6 years. Adult cases are rare but have been reported in women aged 17-46 years. [17, 32, 33, 34, 24, 35, 36]
