Gianotti Crosti syndrome is a skin disorder that can be caused by various viruses, including hepatitis B, Epstein-Barr, and HIV. It appears as papules on the skin, mainly affecting children. Treatment is usually unnecessary, but antihistamines or antibiotics may be prescribed to control symptoms.
Gianotti Crosti syndrome is a skin disorder most commonly associated with the hepatitis virus. The condition, however, can be caused by any of many other viruses. Gianotti Crosti syndrome takes its name from a pair of Italian dermatologists, Agostino Crosti and Ferdinando Gianotti, who first described it. There are several alternative terms; they include acrolocated papulovesicular syndrome, infantile papular acrodermatitis, and infantile papular acrodermatitis.
The main cause of Gianotti Crosti syndrome is any of the three hepatitis viruses that trigger the trio of infectious diseases called hepatitis A, hepatitis B, and hepatitis C. The most common of the three viruses linked to Gianotti Crosti syndrome, however, is the hepatitis B virus (HBV). Other implicated viruses include Epstein-Barr virus, enterovirus, adenovirus, echovirus, and human immunodeficiency virus (HIV). Infections with bacteria such as Streptococcus and Mycoplasma pneumoniae and immunizations for diseases such as polio, measles and influenza are known to cause the disease.
Gianotti Crosti syndrome usually manifests itself as solid bumps called papules that appear on the skin. Each measuring 0.04 to 0.39 inches (1 to 10 millimeters) in diameter, the bumps can be itchy or itchy, although this feature is quite rare. The papules match the color of the skin or show a brownish appearance. Later, though, the bumps, particularly those located on the legs, begin to turn purple, an event attributed to leaky capillaries. In some cases, the rash may have a red color.
Some of the most common sites for bumps are the face, buttocks, arms and thighs. Children between the ages of six months and 12 years make up the main group affected by Gianotti Crosti syndrome. Additionally, doctors have theorized that the bumps that appear exclusively on the face could be caused by the Epstein-Barr virus.
The appearance of papules as indicative of Gianotti Crosti syndrome is typically sudden. Despite this, Gianotti Crosti syndrome is considered a self-limiting disease in the sense that it disappears after a certain period of time. The bumps can stay anywhere from two weeks to four months. Furthermore, it is classified as a harmless condition, as it does not have the ability to cause significant harm to a person’s health.
Therefore, treatment is rarely, if ever, needed. Treatment is typically used only to control some of the symptoms. For example, doctors prescribe oral antihistamines or soothing lotions to reduce itching. In some cases, when associated conditions such as strep throat develop, patients may be prescribed antibiotics.
