Age spots

Introduction to age spots Age spots are brownish black, mostly between 1 mm and 10 mm in diameter, ranging in size. Large spots can reach 2-3 cm in diameter. Most of them are not higher than the skin, and some large spots () can also be higher than the skin. It is flat, it is composed of lipofuscin pigment, which occurs on the exposed skin of the elderly, the back of the hand, the calf, the back of the foot, the trunk, etc., people used to call it "life spot", medically known as Senile pigmented spots (). Age spots are not only found in the skin, but also in the heart, blood vessels, liver and internal gland, affecting the normal function of each organ. Therefore, for age spots, it must not be taken lightly. basic knowledge The proportion of illness: 0.84% (the probability of illness in the elderly over 60 years old is 0.84%) Susceptible people: the elderly Mode of infection: non-infectious Complications: stains

Senile plaque

Cell metabolism (25%):

The first one believes that after entering the old age, the cell metabolism is reduced, the body fat is easily oxidized, and the aging pigment is produced. This pigment can not be excreted, so it is deposited on the cell body to form senile plaques.

Metabolism in the body (35%):

The second is that when people reach old age, their metabolism begins to decline, the decline of cell function is accelerating year by year, the blood circulation is also slow, and the changes in the diet structure and the ratio of plant fat intake. Disorders and other reasons have prompted a tiny brown particle called lipofuscin that accumulates in the basal cells of the skin. This brown particle is a product of lipid peroxidation, and aging tissue cells lose their proper The decomposition and rejection function causes excess brown particles to accumulate in the local cell basal layer, thereby forming age spots on the surface of the human body.

Superoxide dismutase (15%):

The third reason is that the activity of superoxide dismutase with anti-peroxidation in the aged is reduced, and the free radicals are relatively increased. The free radicals and their induced peroxidation react to the long-term toxicity of the organism.

Other (5%):

In addition, the formation and quantity of senile plaques are affected by many factors, some are related to congenital genetic factors, some are related to a lack of certain nutrient factors, and some are related to certain physical factors, such as ultraviolet radiation, which can promote age spots. appear.

Age spot prevention

1, should pay attention to eating spicy food and irritating food in daily life.

2. Try to avoid sunlight.

3. Keep your face clean.

4, quit bad habits, such as smoking, drinking, staying up late.

5. Drink plenty of water and eat more vegetables and fruits.

Senile plaque complications Complications

Under normal conditions, age spots will not cause any harm to the body. No reports of plaque-related complications have been reported. However, if senile plaques are widely present in a short period of time, or a seborrheic keratosis rash is found, it is hard to touch. , keratosis or bleeding, itching symptoms, should go to the hospital in time to rule out the possibility of malignant skin disease or other diseases.

Symptoms of age spots Common symptoms Face spots on the face, dark spots, skin pigmentation, dark spots, light brown spots

Occurs in the face of the elderly, the back of the hand, the calf, the back of the foot, the trunk and other normal bare skin. The age spots are not only found in the skin, but also in the heart, blood vessels, liver and internal gland, affecting the various organs. The function is normal, therefore, for age spots, it must not be taken lightly.

Age spot examination

Diagnosis can usually be made based on clinical symptoms. For inflammatory or irritated skin lesions, pathological examination may be performed to rule out the possibility of basal cell tumor or squamous cell carcinoma or even malignant melanoma.

Pathological examination: A pathological morphological method used to examine pathological changes in organs, tissues or cells of the body. In order to investigate the pathogenesis of organs, tissues or cells, a pathological examination method can be used to examine the pathological changes, to explore the causes, pathogenesis, pathogenesis and development of the lesions, and finally to make pathology. diagnosis. Pathological morphology examination method, first observe the pathological changes of the gross specimen, and then cut a certain size of the diseased tissue, pathological histological method to make a pathological section, further examination of the lesion with a microscope.

Diagnosis of age spots

Diagnostic criteria

The diagnosis points of this disease include:

1, more common in the elderly.

2, the spots are brownish black, the diameter is mostly between 1 mm and 10 mm, the size varies, the large spots can reach 2-3 cm in diameter, most of them are not higher than the skin, and some large spots () can also be higher. The skin is flat.

3, good for the elderly face, hand back, calf, foot back, trunk and other ordinary bare skin.

Differential diagnosis

The disease is combined with clinical and pathological diagnosis, and the diagnosis is not difficult.

However, some of the early damages are like flat warts and must be distinguished from flat warts.

The keratotic lesions that occur at the exposed site are easily confused with senile keratosis (or solar keratosis).

Deep damage to the pigment should be distinguished from sputum cell sputum.

Inflammation or irritated damage can be similar to basal cell tumor or squamous cell carcinoma or even malignant melanoma. In this case, biopsy or surgery should be performed for pathological examination to identify.
