Red and flat skin spots, also known as macules, are discolorations without relief that can appear in various parts of the body. These spots can vary in size and shape and can be the result of several underlying causes. It is essential to know the different factors that can contribute to the appearance of flat red spots on the skin to determine the proper treatment and prevent possible complications.

A common cause of red flat skin spots is a condition known as petechia. Petechia are tiny spots, the size of a pin tip, which occur when the blood vessels located under the skin break, giving rise to small red or purple spots. These spots can be a sign of a more serious underlying disease, such as a hemorrhagic disorder or an infection.

  1. Ulcerative colitis
  2. Leukemia
  3. Thrombocytopenia

IMPORTANT: If you observe flat red spots on the skin that resemble petechiae and do not disappear when applying pressure, it is crucial that you look for medical attention quickly.

In addition to petechiae, another possible cause of flat red spots on the skin is a condition called cherry angiomas. Cherry angiomas are groups of small red or purple spots that may appear on the surface of the skin. These spots are usually harmless and appear frequently in adults over 30 years. However, if you notice any change in the size, shape or color of these spots, it is advisable to consult a health professional.

The treatment of flat red spots varies depending on the underlying cause. In some cases, no treatment may be necessary, especially if the spots are benign and are not associated with any other symptoms. However, for conditions such as petechiae or cherry angiomas that can be indicative of an underlying health problem, it is important to consult with a healthcare professional to determine the appropriate course of action.

Flat Red Skin Spots: Causes, Symptoms, and Treatment


  • Hyperpigmentation: flat red spots may appear on the skin due to an overproduction of melanin, the pigment responsible for skin color. This excessive melanin deposit can occur in response to sun exposure, hormonal changes or certain medications.
  • Capillary malformations: known as vascular birth marks, these flat red spots are caused by abnormal blood vessels near the skin surface. They are usually present from birth and, although they are harmless, may require treatment if they affect sel f-esteem or give rise to complications.
  • Acne or acne scars: acne outbreaks can leave flat red spots, commonly called pos t-inflammatory hyperpigmentation. These spots can persist for a prolonged period after the initial acne injury has been cured, so they require specialized treatment.

It is essential to consult a dermatologist to obtain a precise diagnosis and determine the specific cause of flat red spots on the skin. Only a trained medical professional can provide adequate guidance for the particular situation of each person.

Common Causes of Flat Red Skin Spots

1. 1. Allergic reactions: A possible cause of flat red spots on the skin is an allergic reaction. Exposure to certain allergens, such as food, medications or environmental irritants, can trigger an immune response in some people. This immune response can lead to the release of histamine, a compound that dilates blood vessels and causes skin redness and inflammation. It is itching, swelling and the presence of ranch or high protuberances can also accompany flat red spots.

  • Allergies: Allergies to substances such as pollen, domestic animals dandruff, certain foods or medications can cause flat red spots on the skin.

For example, a common fungal infection called Tiña Versicolor can lead to red or pinkish skin spots on the skin. Viral infections, such as measles or rubella, can also produce flat red spots that usually start on the face and spread to other areas of the body. The presence of other symptoms, such as fever, pain or swelling, can help differentiate between different types of skin infections.

  1. Bacterial infections: skin infections caused by bacteria, such as cellulite or impetigo, can cause the appearance of red and flat skin spots.
  2. Viral infections: certain viral infections, such as measles, rubella or roséola, can manifest as flat red spots on the skin.

Diagnosing Flat Red Skin Spots: Tests and Examinations

Flat red spots on the skin can be a common manifestation of various dermatological conditions, from benign skin conditions to more serious systemic diseases. When a patient develops flat red spots on the skin, healthcare professionals use a combination of tests and examinations to accurately diagnose the underlying cause of these spots.

Physical examination plays a crucial role in the initial evaluation of flat red skin patches. The healthcare professional visually inspects the spots, observing their size, shape, color and distribution on the body. Any associated symptoms, such as itching, pain, or peeling, are also evaluated. The patient’s medical history is reviewed, including known allergies, previous skin conditions, or recent exposure to irritants or allergens. This information helps the healthcare professional narrow down possible causes and determine the appropriate diagnostic approach.

Table 1: Common dermatological conditions associated with flat red skin spots

  • Dermatological condition Characteristics
    Allergic contact dermatitis Flat red spots accompanied by itching and localized inflammation
    Pityriasis rosea Oval-shaped scaly spots with a characteristic “Christmas tree” pattern
    Psoriasis Well-defined red plates covered with silvery scales
    lichen planus Flat, itchy, purplish-red bumps with thin white lines

    Further diagnostic testing may be necessary to confirm the suspected diagnosis and rule out other possible causes. A common procedure is a skin biopsy, in which a small sample of the affected skin is removed and examined under a microscope. This helps identify any characteristic changes or abnormalities in the skin layers. Blood tests may also be performed to evaluate specific markers or detect underlying systemic conditions associated with flat red spots on the skin. Allergy testing may be helpful if an allergic reaction is suspected to be the cause.

    Treatment Options for Flat Red Skin Spots

    1. Topical creams and ointments: One of the most common treatment options for flat red spots on the skin is the use of topical creams and ointments. These products often contain ingredients such as hydrocortisone, retinoids, or benzoyl peroxide, which can help reduce inflammation and improve the appearance of spots. It is important to follow the instructions of a healthcare professional or the product label when using these topical treatments.

    1. Hydrocortisone cream: This over-the-counter cream can help reduce the redness and itching associated with flat red patches on the skin. It is a mild steroid that works by reducing inflammation in the affected area. Apply a thin layer of cream to the spots twice a day, or as directed by a healthcare professional.
    2. Retinoid creams: A dermatologist may prescribe retinoid creams, such as tretinoin or adapalene, to treat flat red spots on the skin caused by acne or sun damage. These creams help eliminate dead skin cells, unclog pores and promote cell renewal, resulting in a smoother and more uniform complexion. Apply a small amount of cream to the spots once a day, following your dermatologist’s instructions.

    Note: It is important to avoid excessive sun exposure while using retinoid creams as it can increase sun sensitivity and cause sunburn. Always apply a broad-spectrum sunscreen with a high SPF when you go outside.

    2. Laser treatment:

    Laser treatment is another option to reduce the appearance of flat red spots on the skin. This procedure uses concentrated beams of light to destroy pigment-producing cells in the affected area, resulting in a more even skin tone. Laser treatment can be an effective solution for people with persistent or stubborn red spots. However, it is important to consult a dermatologist to determine if laser treatment is appropriate for your specific case.
