TipsForWomens sheds light on this rare disease.

Gianotti-Crosti syndrome or infantile papular acrodermatitis

Gianotti-Crosti syndrome or Gianotti-Crosti disease is a benign disease that mainly affects children between 1 and 5 years old. It is characterized by a rash that usually begins with the lower and upper limbs and then on the trunk and abdomen. This rash takes the form of small pink pimples with a diameter that varies between 5 and 10 millimeters. The itching (or pruritus) that accompanies the rash is the most bothersome symptom for little patients.

This disease usually occurs after a viral infection (Epstein-Barr virus, infectious mononucleosis (MNT), hepatitis A virus, hepatitis B virus, adenovirus 1 and 2, cytomegalovirus, echovirus 8, Coxsackie virus A16, respiratory syncytial virus). More rarely, it follows a vaccination.

If Gianotti-Crosti syndrome is an underlying consequence of a more serious pathology such as hepatitis B, certain symptoms such as jaundice or enlargement of the liver (hepatomegaly) may be observed.

What treatments for Gianotti-Crosti disease?

In most cases, the disease is mild and resolves itself within 1 to 6 weeks. The doctor or pediatrician may prescribe medication to relieve the itching if the child is uncomfortable.

If the underlying cause is more serious, the treatment will depend on the pathology in question.

Regarding the son of Mandy Moore, it was, a priori, a benign cause. The actress said she was relieved by the diagnosis and the proposed treatment (steroid cream and Benadryl, an antihistamine) to relieve her baby.
