“Aren’t many people with onychomycosis? Why did mine turn into a tumor? Could it be a mistake?” With the diagnosis report, Aunt Li was reluctant to believe that she Diagnosed with malignant melanoma.

Aunt Li, 58 years old, three years ago discovered that she had a dark “line” on her right big toe “, it didn’t hurt or itch at first, so Aunt Li didn’t care. Also getting bigger,looks like “nail fungus”. Aunt Li went to the pedicure shop for nursing care, but the technician said that it could not be repaired and she had to go to the hospital. Aunt Li still ignored it and did not follow the advice of the technician.

As of early February today,the big toenail has turned black, Aunt Li was flustered and came to the hospital for examination. The result was diagnosed by dermoscopy and pathological examination, and it was actually Malignant melanoma!

In this regard, the doctor reminds: malignant melanoma is often “silent” in the development process, and it rarely occurs itching, infection, pain and other symptoms. If it is found that the nails are abnormally black and are not painful or itchy, you need to seek medical attention in time to find out the cause, so as not to miss the opportunity for treatment.

First, “onychomycosis” and “melanoma”, don’t be foolishly confused

“Onychomycosis, one infection infects two”, in people’s impression, besides affecting the appearance and infectivity, onychomycosis does not seem to do much harm to the human body, but on Aunt Li’s body, The mediocre onychomycosis turned out to be the “forward” of melanoma, which made her puzzled. In fact, graying and blackening of the nails is sometimes a signal of cancer, but onychomycosis does not turn into a malignant tumor.

Onychomycosisis a type of onychomycosis. Onychomycosis, as the name suggests, is caused by fungal infections, such as: yeast, dermatophytes, molds, etc. There are two ways of fungal infection, one is the spread of tinea pedis, and the other is body-skin contact infection, called Onychomycosis, also known as onychomycosis, is also known as “chicken feet wind” in traditional Chinese medicine.

Melanoma is a skin tumor caused by the malignant proliferation of melanocytes. It is normal skin lesions, pigmented nevus malignant transformation. The black line produced by melanoma is often more than 3 mm, and the nail symptoms are mostly concentrated in the thumb, index finger and other parts of the hands and feet, and it can cause skin lesions around the nail, < /strong>This is also the biggest difference from simple onychomycosis.

Although melanoma can also cause symptoms similar to onychomycosis or nail lesions, there is no clear relationship between onychomycosis and melanoma in terms of pathological mechanism. Not to be confused.

• There are 4 kinds of nails, beware of the signs of cancer

< span>When the body tissue becomes cancerous and affects the nails, it can often be judged by the color, texture and shape of the nails. Special attention should be paid to these four situations:

①Black or red patches on the skin near the nails;

②Unexplained broken or raised nails;

③Black or red longitudinal plaques appear on the nail itself;

④The proliferation of “unidentified objects” in or around the nails.

If the above abnormal changes occur in the nails, you should be alert to the signs of cancer, and go to the hospital in time for dermoscopy, chest CT, and cardiac color Doppler ultrasound to investigate the cause.

Second, nails are “signal lights” for health, so pay attention to these abnormalities

Small fingernails (toenails) are located at the ends of the limbs. Systemic diseases can easily affect the blood supply and growth of the fingertips, resulting in changes in the appearance and shape of the fingertips and nails. Some extensive skin lesions can also affect the nail plate and periungual tissue, resulting in changes in the color, texture and shape of the nail plate, and even peeling off in severe cases, affecting the appearance and function.

When the following 4 symptoms appear on the nails, you must pay attention to observation, seek medical treatment and treatment in time.

1. Color faults

The nails of healthy people generally maintain a stable shape and The color will also recover quickly after being pressed and discolored, so the fault of the nail color is often related to the disease. When one half of the nail is white and the other half is red, pink, or brown, it may be associated with chronic kidney disease, medically known as lint Saigon’s nail, the enlargement of the originally tiny white crescents on the nails, may also be affected by kidney disease.

In addition, black spots appear on the nails, forming a contrast between black and white, called black nails< span>, it may be the melanin deposition caused by freckled nevus or nevus on the nail matrix, which is not harmful to health, but it may also be caused by the same melanoma as Aunt Li, and it should be screened in time.

2, abnormal discoloration

The nail itself is white and transparent, but under the influence of blood, the appearance is generally red or pink. When the color of the nail changes, it indicates the arrival of disease. The original red color of the nail fades or moves to the upper end, showing gray or white, which may be related to anemia, liver cirrhosis, acute blood loss, etc. The nail turning blue may indicate the risk of stroke .

In addition, dead blackmay be a weakened heart, kidney disease , gastric bleeding and other diseases, withered yellowmay be a side effect of liver and gall disease or indigestion,Dry whitemay indicate insufficient blood and respiratory diseases. If there is no large area of ​​discoloration, just white spotsor it means excessive fatigue and calcium deficiency; Red spotsmay signal a skin disorder, high blood pressure, or heart disease.

3. With transverse grooves

The nails may appear crescents at different growth stages , dents, transverse striations, etc., while transverse grooves may indicate disease. The indentations that run across the surface of the nail are medically named “Bauer’s lines”, and appear to be caused by nail cells stopping dividing Yes, the root cause may be malnutrition, pneumonia, measles, heart disease, etc. Therefore, you should seek medical attention to find out the cause of such symptoms.

4. The appearance of a clubbed finger

The clubbed finger does not necessarily represent a disease. But it is a typical symptom of many diseases, so it should also be prepared. In normal fingers, the angle formed between the fingernail and the first joint is 160 degrees after straightening, while club fingers are usually greater than 180 degrees and look similar to a pestle< /strong>, hence the name.

The clubbing may be related to cardiovascular disease, gastrointestinal disease or lung disease. During treatment, symptoms can be checked in a targeted manner. If there are no obvious symptoms, it can be To general medical examination, diagnosis.

Third, the more “crescents” on the nails, the better?

In life, people give special meaning to the “crescent”, “horizontal” and “dent” on the nails, especially the infinite reverie brought by the crescent. Let people see it as a sign of good luck and good fortune. However, this view is not supported by science.

The so-called “crescent moon” is actually a new nail. Because keratin leukocytes have just been produced, they have not fully grown into nails, which is medically called “keratinization”. At this time, keratin leukocytes are generally gathered in the middle part of the bottom of the nail, and the number of the outer side decreases, so it looks like a “crescent moon”.

Strictly speaking, everyone has crescents,and the number and shape of crescents depends on genetics and how fast the nails grow , has nothing to do with human health.

Although modern medicine has made great progress, it is only a glimpse into the mystery of the human body. For the connection between some diseases and symptoms, There is still room and necessity for continued exploration. In life, people should also maintain a reverence for life, learn to observe their own symptoms, and use medical knowledge to protect their health! #Health Star Project# # Yao Zero Zero Project#
