Reactive gastropathy, chemical gastropathy also called gastritis of « C type » or "chemical gastritis" is an abnormality in the stomach caused by chemicals, e.g. bile, alcohol, and characteristically has minimal inflammation. Cause
Reactive gastropathy has a large number of causes, including:

Alcohol use disorder. Bile reflux, such as may be seen post-Billroth II. NSAIDs. Diagnosis
The diagnosis is by examination of tissue, e.g. a stomach biopsy. Relation to gastritis
Reactive gastropathy is morphologically distinct entity  that can be separated from gastritis, which by definition has a significant inflammatory component. As a reactive gastropathy may mimic a (true) gastritis symptomatically and visually in an endoscopic examination, it may incorrectly be referred to as a gastritis. Even aware of the underlying etiology of the pathologic process, e.g. NSAID use, the label "chemical gastritis" is applied to a chemical gastropathy. See also

It is more common in children between the ages of one and ten years old. The condition has become more common in the United States since 1966. But having an infection is not a reason to keep a child out of school or daycare. Signs and symptoms
Molluscum contagiosum lesions are flesh-colored, dome-shaped, and pearly in appearance. They are often 1–5 mm in diameter, with a dimpled center. Molluscum lesions are most commonly found on the face, arms, legs, torso, and armpits in children. Adults typically have molluscum lesions in the genital region and this is considered to be a sexually transmitted infection; because of this, if genital lesions are found on a child, sexual abuse should be suspected. These lesions are generally not painful, but they may itch or become irritated. Picking or scratching the bumps may lead to a spread of the viral infection responsible for molluscum contagiosum, an additional bacterial infection, and scarring. In some cases, eczema develops around the lesions.Individual molluscum lesions may go away on their own within two months and generally clear completely without treatment or scarring in six to twelve months. Mean durations for an outbreak are variously reported from eight to about 18 months, but durations are reported as widely as six months to five years, lasting longer in immunosuppressed individuals. Transmission
As the name implies, molluscum contagiosum is extremely contagious.
