Melanoma 20, Melanoma melanoma

Melanoma: a type of tumor, mainly distributed on the surface, so it is also a pre-symptom of cancer, with a high mortality rate, and should be diagnosed in time. Melanoma occurs more often in middle-aged and elderly people, and it is more common in men than women.

It is common to develop the lower limbs and feet, followed by the trunk, head and neck, and upper limbs. Symptoms are mainly melanonodules that grow rapidly. Melanosis may occur at the beginning of normal**, or pigmented nevi may be hyperpigmented and darkened, followed by expanding lesion damage, increased hardness, and itching sensation.

Melanoma lesions may be raised, plaque-like, and nodular-shaped, while others may be mushroom-like or cauliflower-like. When it grows into the subcutaneous tissue, it appears as a subcutaneous nodule or lump, and if it spreads around, it appears as a stellate dark spot or small nodule. The most common manifestation is regional lymph node metastasis of melanoma, or even regional lymphadenopathy.

In the late stage, it metastasizes from the bloodstream to the lungs, liver, bones, and brain organs.

Pathology is recommended to rule out the possibility of melanoma, melanoma has a poor prognosis, and should be diagnosed as soon as possible so as not to delay the condition.

Dr. Wang Jinghua of the General Hospital of Nanjing Military Region solemnly reminded that because the patient cannot be seen face-to-face and cannot fully understand the condition, the above suggestions are for reference only, and the specific diagnosis and treatment must be carried out in the hospital under the guidance of the doctor! ）

Summary. Hello, dark spots on the nails are not necessarily melanoma. Because after the appearance of melanoma, it will generally grow faster, if you are more worried, you can go to the hospital for a pathological examination, you can make a clear judgment.

After melanoma is ruled out, a trace element test can be done in the hospital, because dark spots on the nails may be caused by a lack of trace elements, such as zinc deficiency and calcium deficiency, etc., if the diagnosis is confirmed in time, zinc and calcium supplementation can be relieved.

Hello, dark spots on the nails are not necessarily black marlinoma. Because after the appearance of melanoma, it will generally grow faster, if you are more worried, you can go to the hospital for a pathological examination, you can make a clear judgment. After melanoma is ruled out, a trace element cavity skin test can be done in the hospital, because the appearance of dark spots on the nails may be caused by a lack of trace elements, such as zinc deficiency and calcium deficiency, etc., if the diagnosis is confirmed in time, zinc supplementation can be relieved.

What is this?

I would like to ask you, how long has this been going on? Does it hurt? Does it affect walking?

According to your situation, subungual pigmented nevus, subungual hemorrhage, onychomycosis and other factors can be caused, the specific contents are as follows: 1. Subungual pigmented nevus: It is the position where the pigmented nevus grows at the root of the nail, which is a benign disease with abnormal proliferation of melanocytes on the nail matrix and aggregation of dark spots; When the width of the nail black line is 3mm, the nail black line widens significantly in a short period of time, and the nail plate of the nail black line is damaged, it is necessary to be alert to early malignant melanoma, and it is necessary to go to the hospital for histopathological examination, and if necessary, surgical resection.

2. Subungual hemorrhage: mainly bleeding caused by the squeeze of the nail by trauma, most of which do not need to be absorbed and relieved by themselves; A small number of patients have aplastic disorders, spring anemia and other diseases, and the early base will also cause subungual hemorrhage, so they can go to the hospital for a detailed examination. 3. Onychomycosis:

Mainly caused by fungal infection, it is a kind of athlete's foot, you can use urea ointment to soften the nails and scrape off the diseased nails, and apply antifungal drugs such as itraconazole, fluconazole, etc. to the affected area**.

Whether it is subungual bruising or melanoma can only be determined after further examination and diagnosis, just seeing subungual black stasis cannot be arbitrarily assumed that it is suffering from melanoma, it is recommended to go to the hospital for a comprehensive examination before making a judgment.

This is still some bruising, melanoma is not very likely, don't worry, this is still the case of wearing shoes and compression. The upper surgery of melanoma is the main one, and the combination of traditional Chinese medicine such as ginsenoside rh2 can reduce the complications of surgery and improve the effect of surgery.

It was subcutaneous bleeding, it must have been injured without thinking, it's fine! As long as there is no redness, swelling and pain, it will slowly absorb or push out the black ones as the nail lengthens ....... It may be a long time, about a few months. Wishing you health and happiness.

Melanoma often occurs in any part of the country and is a malignant tumor. A normal person's nails should be smooth, nail melanoma shiny, reddish. In the ** outpatient clinic, it can be seen that the nails of some patients have changed color, such as white, black, red, yellow, green, gray, etc.

Color changes are often associated with a number of disorders, in which the color of the nails becomes darker (i.e., black nails) and the darker ones become more and more extensive, and a high level of suspicion should be exercised because the main cause of black nails (usually in the thumb or toe) is subungual malignant melanoma and should be operated on as soon as possible**.

Metastasis and spread of malignant melanoma is extremely common, and nail melanoma is the first lymphatic metastasis, and the circulation spread occurs later, but once it occurs, it is easy to metastasize extensively. After a small number of patients have extensive metastasis, the whole body can become black, and grayish-blue, if metastasis has occurred, the prognosis is poor, if the disease can be operated in early and timely times, it can save lives, and the late stage is often not easy to control the development of the disease, so it is worth paying attention to and being vigilant.

Malignant melanoma is a highly malignant tumor, which is more common in **, accounting for the third place in **malignant tumors (accounting for 1% of cancer deaths in foreign statistics).

If you have a darkening of your nails, it may be melanoma**, or it may be caused by bruising or infection of your nails. It is recommended to go to the hospital for a re-examination, do not rub the nails excessively, keep **dry, if there is a malignant transformation, it is recommended to do surgery to remove it, don't worry too much.

Acral pigmented melanoma mainly occurs in the palms, soles of the feet and under the nails, the skin lesions in the radiation growth period are brownish, brown or black, not higher than the skin surface, if irregular brown or brown streaks can be seen under the nails from the nail bed to the proximal extension, the radiation growth period lasts for about 1 year, and if not treated in time, it enters the vertical growth phase, the lesion is a nodular bulge, the lymph node metastasis rate also increases, and the prognosis is also poor.

Differential diagnoses include basal cell carcinoma, seborrheic keratosis, dysplastic nevi, blue nevi, fibroids, nevi of various types, hemangiomas (especially hands and feet), venous lakes, pyogenic granulomas and warts. If in doubt, a full-thickness biopsy** that extends slightly beyond the lesion must be performed. Excisional biopsy is performed for minor lesions and incisional biopsy for larger lesions.

Serial biopsies can determine the depth of invasion of melanoma, and thorough surgery must be performed only after a clear histologic diagnosis has been made. Criteria for excision or biopsy of pigmented lesions include recent enlargement, darkening, hemorrhage, or ulceration.

However, the above symptoms often indicate that melanoma has invaded the deep layer. When the lesion changes color (eg, brown or black mixed with red, white, or blue background), irregular bulges that are visible or palpable, angular serrated at the edges, or notched, the lesion should be biopsied immediately to allow for early diagnosis. Examination of pigmented lesions with a ** lens (a modified type of glasses soaked in oil) can help distinguish melanoma from benign lesions.

Histological judgment** and prognosis are primarily determined by microscopic observation of the depth of histological invasion in melanoma. Histologic grading requires an adequate biopsy. Central nervous system and subungual melanoma are generally not classified by these systems.

I personally think it's melanoma.

Melanoma is divided into benign and malignant, and the following four aspects will compare the difference between benign melanoma and malignant melanoma.

Asymmetry: Common nevi are symmetrical in both halves, while malignant melanoma is asymmetrical in both halves.

Margins: The edges of ordinary moles are smooth and clearly demarcated from the surrounding **, while the edges of malignant melanoma are irregular and jagged. In addition, the surface is rough with scaly or flaky desquamation, sometimes oozing or bleeding, and the lesion is higher than **.

Color: Common moles are usually brownish-yellow, brown, or black, while malignant melanoma is doped with pink, white, blue-black, on top of brownish-yellow or tan. Among them, blue is the most ominous, and white indicates that the tumor has spontaneous degeneration.

Nodular malignant melanoma is always blue-black or gray in color.

Diameter: Common moles are generally less than 5 mm in diameter, while malignant melanoma is more than 5 mm in diameter.

In addition, special attention should be paid to itchy and painful nevi, if this type of nevus continues to develop, it is likely to have ulcerative lesions, stinging or burning pain, and satellite nodules or regional lymphadenopathy will appear around it, indicating that the disease has progressed to an advanced stage. It should be emphasized that the distinction between a poorly structured nevus and an early malignant melanoma is difficult to distinguish by visual observation alone, and a biopsy should be performed in time to obtain a pathological diagnosis for suspected lesions.

Malignant melanoma includes surgery, chemotherapy, radiotherapy, and immunity. Among them, radiotherapy can be used for metastases in malignant melanoma; Chemotherapy is an important method of postoperative prevention** and metastasis.

Therefore, the first thing about melanoma is to distinguish whether it is benign or malignant, so that it can be detected early.

I recommend that you better go to the hospital for a check-up, in case it is melanoma as soon as possible**.

It's best to go to the hospital. For that melanoma you're talking about, probably shouldn't be. Please take a day off to go to the ** department of the hospital. It's safer this way. The body is the most important.

1 Clubbing: The nail arches prominently upwards and curls around the fingers. Swollen nail clubbing may indicate emphysema, tuberculosis, cardiovascular disease, ulcerative colitis, or cirrhosis.

2 Blue crescent: A crescent-shaped white mark at the base of the nail with a blue halo may indicate any of the following conditions: obstruction of blood circulation, heart disease, Raynaud's symptoms, and vasospasm of the fingers and toes, usually due to a previous exposure to freezing.

But sometimes it is also associated with rheumatoid arthritis or the autoimmune disease lupus erythematosus.

3 Spoon-shaped nails: The middle of the nail is sunken and the entire nail becomes flat or spoon-shaped. This type of nail is associated with iron deficiency anemia, syphilis, thyroid disorders, rheumatic fever, etc.

4 Lindsay's nails: Pink or brown in the near half of the nail tip and white in the near nailoid form, this type of nail, also known as bisectional nails, may be a sign of chronic kidney failure.
