Be careful not to confuse coffee spots with any disease

The light brown patches that can be found at birth of coffee spots range in color from light brown to dark brown, but the color of each patch is the same and very uniform, the depth is not affected by sun exposure, the size varies from a few millimeters to tens of centimeters, the boundary is clear, and the surface texture is completely normal. The presentation is very similar to that of freckles, with an abnormally high amount of melanin in the epidermis, but the number of melanocytes is normal.

To distinguish coffee spots from freckles, it is recommended to go to a regular specialist hospital.

Like physiologic coffee spots, pathological coffee spots can appear in newborn babies and increase in number throughout childhood. Coffee spots can appear on any part of the body and do not disappear once they appear. If you want to make the coffee spots disappear, you have to go to the hospital for treatment.

Pathological coffee spots also have some characteristics that physiological coffee spots do not have. In general, pathological coffee spots are more regular in shape, generally oval or willow-leafed, while physiological coffee spots are generally irregular in shape. Of course, irregular coffee spots are not necessarily physiological coffee spots, and regular coffee spots are not necessarily pathological coffee spots.

The specific type depends on the inspection.

In addition, pathological coffee spots are usually larger in size and appear in large numbers. If a child has six or more coffee spots with a diameter of more than 1.5 cm, there should be a high suspicion that the child's coffee spots are pathological. There is a high probability that pathological coffee spots will develop into neurofibromas, and once neurofibromatosis occurs, it cannot be completely **.

Coffee spots, also known as coffee au lait spots, are similar in color to the color of coffee mixed with milk, and are more common pigmentation ** diseases, 10% to 20% of normal people can see a single coffee spot at birth. The color of the coffee spots ranges from light brown, tan to dark brown, but the color of each piece is the same and very uniform, the depth is not affected by sunlight, the size is from a few millimeters to tens of centimeters, the boundary is clear, and the surface texture is completely normal.

The cause of coffee spots is mainly a manifestation of a lesion, which can appear at birth, or gradually appear later after birth, and increase in size throughout childhood, coffee spots are hereditary ** diseases.

Melanocytes and keratinocytes in pigmented plaques in this disease are hyperactive, producing a large amount of melanin and forming pigmented plaques.

Women after the age of 30, facial attacks are more serious erythema, inflammatory papules, nodules, pustules and other acne-like lesions, according to the effect of acne ** is not obvious, if accompanied by prolonged menstruation or intermittent amenorrhea, obesity, constipation and other symptoms, then it is necessary to do a **B ultrasound examination to see if it is "multi-hu shed ovarian cyst".

Cultivation techniques. Peach leaf coral is a dioecious plant, which is cultivated with a combination of male and female plants with multiple seeds. When repotting in the spring, pay attention to root and shoot pruning. Transplanting should be carried out in spring or during the rainy season.

In summer, the soil is moist and shaded. Fertilize once a month, and increase phosphorus and potassium fertilizer 1 or 2 times in autumn.

Peachleaf coral grows vigorously and is extensively managed. Cultivation can use peat soil (2 parts) and coarse sand (1 part) mixed soil, before planting to apply a small amount of basal fertilizer, during the growth period every 3 4 weeks to water 1 liquid fertilizer, and keep the potting soil moist, placed in semi-shade, avoid direct sunlight. Keep greenhouse temperatures above 10 in winter and reduce watering.

Rarely susceptible to pests and diseases. [5]

It can be propagated by sowing method and cuttings, and for varieties that are difficult to survive by cuttings, seedlings can be used as rootstocks for grafting. The best time is in the mildew rainy season in May and June, and the semi-lignified branches of the current year are selected, 15 cm long, leaving 2 leaves, and the survival rate is more than 95%.

Pest control. Peach leaf coral is a negative plant, not tolerant to strong sunlight, midsummer poison daily to make its young leaves burn seriously, resulting in young leaves curled and yellow or leaves scorched, seriously affecting the growth of plants, some pathogenic bacteria take advantage of the void to enter, further cause infectious diseases, now some lesions can be seen in the fruiting body of the fungus. Rhododendron is a semi-negative plant, and its scorched leaf disease is similar to the above, and the young leaves are more serious, which causes a large number of abnormal defoliation of plants. [6]

It is mainly harmed by anthracnose and brown spot, and when cultivated indoors, there are red spiders and scale insects. Prevention and control methods: Due to the sudden and strong wind and rain in midsummer, it is necessary to remove the existing diseased leaves and fallen leaves on the ground in time and destroy them on the spot, so as to avoid the existing pathogens from expanding the scope of infection by wind and rain; Strengthen management, enhance the growth potential of trees, and improve the disease resistance of plants; Spraying inhibits the development and spread of the disease, chlorothalonil 800 times liquid, Markor 3000-4000 times liquid, sprayed once every 7-10 days.

6] Dutch iron is an evergreen woody plant that can reach a height of 10 meters in its native region (warm regions of North America) and a plant height of 1 to 2 meters in potted plants. width about 8-10 cm; The leaves are leathery, tough, entire, green, sessile, and are commonly propagated by cuttings.

Coffee spots are a type of pigmented birthmark, due to the increase in melanocytes and keratinogenesis in the epidermis, the melanocytes are hyperactive, producing a large amount of melanin, forming pigmentation. The melanocytes in the epidermis determine the color of **, if there are more melanocytes than the normal value, it will lead to **abnormalities and the formation of coffee spots. **Coffee spots are recommended to go to a regular hospital**, which can ensure the **effect, I wish you soon**.

Coffee spots are mostly hereditary** diseases and have nothing to do with sun exposure. Coffee spots are persistent pigmented spots of varying size, round, oval, or irregularly shaped with a smooth surface. Coffee spots are mostly light brown to dark brown spots or patches, like a mixture of coffee and milk, so they are also called café au lait spots.
