View detailsHenoch-Schönlein purpura
Henoch-Schönlein purpura (HSP) is a hypersensitivity vasculitis affecting small blood vessels throughout the body. It is primarily characterized by dark purple patches on the skin and mucous membranes, which may be accompanied by rash, joint pain, abdominal pain, and kidney damage. It is more common in children and adolescents, with a higher incidence in males than females. Common Questions Q: Is Henoch-Schönlein purpura an allergy? A: Henoch-Schönlein purpura is not an allergy. Henoch-Schönlein purpura is an older term that is still widely used, but IgA vasculitis is a more appropriate name. There is no involvement of "allergy." Therefore, using anti-allergy medications to treat "Henoch-Schönlein purpura" is also incorrect.

Café au lait spots, also known as café au lait macules, are named for their light brown appearance (resembling a mixture of coffee and milk). They are a relatively common pigmented skin condition. Café au lait spots are light to dark brown macules or patches with clear borders, ranging in size from a few millimeters to tens of centimeters, and can vary in shape. However, the skin texture remains normal. Café au lait spots do not become malignant and generally do not require treatment. However, if cosmetic concerns exist, laser treatment can be chosen, though recurrence is possible after treatment.
