Gianotti–Crosti syndrome (GCS), also known as papular acrodermatitis of childhood and infantile papular acrodermatitis, is a skin disease in children that is characterized by a rash on the legs, buttocks, and arms. It is often associated with viral infections.

Causes

GCS is often associated with viral infections, including hepatitis B, Epstein-Barr virus, cytomegalovirus, coxsackievirus, echovirus, adenovirus, enterovirus, rotavirus, parainfluenza virus, respiratory syncytial virus, mumps virus, influenza virus, and human immunodeficiency virus.

Symptoms

The primary symptom of GCS is a rash that appears on the arms, legs, and buttocks. The rash is often symmetrical and may be accompanied by fever, fatigue, and malaise. Other symptoms may include lymphadenopathy, hepatomegaly, and splenomegaly.

Diagnosis

The diagnosis of GCS is primarily based on the clinical presentation. Laboratory tests may be used to identify the underlying viral infection. A skin biopsy may be performed in some cases to confirm the diagnosis.

Treatment

There is no specific treatment for GCS. The condition usually resolves on its own within a few weeks. Treatment is primarily supportive and may include antihistamines to relieve itching and analgesics to relieve pain.

Prognosis

The prognosis for GCS is generally good. The condition usually resolves on its own within a few weeks. However, in some cases, the rash may persist for several months.
