These spots can have multiple causes ranging from acute skin infections to serious conditions. They may appear as tiny red bumps with scaly skin or even flat patches. Sometimes, these spots can be accompanied by swollen skin and pus-like discharge.
However, the symptoms and appearance vary according to the underlying condition. Therefore, it is necessary to learn the causes of these spots. Keep reading to learn more about it.
What Causes Red Spots On Skin

Leukemia
Leukemias are serious cancers that affect the blood and bone marrow. When leukemia affects the skin, you notice small bumps and spots on the skin called leukemia cutis (1). These bumps or spots appear as red or purplish-red dots or patches, sometimes darker in color. It affects the layers of the skin and tissue beneath it.
Symptoms of leukemia include:

Treatment
In this case, seeking medical care is important. Treatment for red spots due to leukemia typically involves chemotherapyi tailored to the specific type of cancer.

In some instances, radiation therapy may be used for more challenging cases or to alleviate symptoms.
Cherry Angioma
Cherry angiomas are the most common type of skin growth caused by blood vessels. They look like small, bright red bumps with a pale ring around them. They usually appear as multiple spots on the trunk or upper arms and legs and are rarely found on the face, hands, or feet.
Symptoms of cherry angioma include:
- Red, flat spots and grow into 1 to 5 mm red bumps
- May bleed if injured
- May turn blue in some cases
- Treatment
These spots are usually asymptomatic but may bleed if injured. Some people may choose to remove them for cosmetic reasons or to prevent bleeding. The treatment to remove small spots involves local anesthesia followed by electrocauterizationi . Larger spots are typically treated with shave excisioni combined with electrocauterization.
Heat Rash
A heat rash may result in small, red, itchy, and prickly spots on the skin. It typically appears in areas where sweat collects, such as the groin, chest, back, arms, and armpits (5).The spots appear as tiny blisters, about 1 to 2 mm in size, and affect adults and newborns typically under 2 weeks old.
Symptoms of heat rash include:
- Groups of small, firm, and flesh-colored bumps

It is best recommended to consult a dermatologist to check which type of heat rash you have and what is the best course of action.
Keratosis Pilaris
This condition typically manifests as small bumps around the hair follicles with redness. People with keratosis pilaris have red, bumpy skin that isn’t painful or itchy (6).

Sometimes, treatments like retinoids or vitamin D creams and chemical peels with glycolic acid may also help improve the condition.
Contact Dermatitis
This is a common skin allergy triggered by contact with an allergen or irritant, resulting in an itchy, red rash (7). Symptoms typically appear 1 to 3 days after exposure to the trigger and peak around 3 to 4 days later.

Treating contact dermatitis depends on its main cause and how bad the symptoms are. Mild to moderate cases of dermatitis usually get better if you avoid whatever caused the irritation. This means you may have to avoid harsh chemicals in skin products, nickel or gold jewelry, certain foods, or medicines that may trigger allergic reactions. You can also use over-the-counter 1% hydrocortisone cream if the symptoms are mild. If that does not help, consult a doctor who can prescribe stronger steroid creams if needed.
Atopic Dermatitis
Atopic dermatitis is the most common chronic inflammatory skin disease and a type of eczema. The condition’s symptoms vary by age. Infants develop swollen bumps and plaques, sometimes with blisters or crusts, on the scalp, face, and arms or legs while adults often have thickened skin patches, mainly on the hands.

Symptoms of atopic dermatitis include:
- Swollen, red bumps
- Plaques with blisters or crusting
