There are many reasons why small red dots are found on the body. If the patient has a history of allergies with itching and scattered red dots on the body, it could be dermatitis or eczema. Red dots on the body can also be spider nevi, which often appear as small, early, scattered red dots when they appear. Radially dilated capillaries can be found next to the small red dots of spider nevus. The occurrence of spider nevus may be related to the liver system, such as hepatitis. In addition, there may be capillary hemangiomas, such as scattered or single red dots found on young children after birth. In young children, hemangiomas can become progressively larger with age and protrude from the surface of the skin. For small red dots on the body with these symptoms, it is important to go to the hospital early for treatment.
