Pay attention to these symptoms!

1. Acanthosis nigricans

is manifested as symmetrical melanin deposition in the neck, armpits, perineum, umbilicus, etc., and local skin shows keratin hyperplasia with a wide range of lesions.

Acanthosis nigricans is divided into benign acanthosis nigricans, which is not accompanied by visceral tumors, and malignant acanthosis nigricans, which is often associated with adenocarcinoma of the internal organs.

Malignant acanthosis

nigricans: Malignant acanthosis nigricans is almost always associated with visceral tumors. About 60% of patients had skin symptoms that progressed simultaneously with visceral malignancy, about 20% of patients had skin symptoms that preceded malignant tumors by several years, and about 20% of patients had malignant tumors that were primary and dermatological diseases were secondary.

The cutaneous manifestations of this paraneoplastic syndrome usually occur in adults. Cutaneous symptoms usually resolve after tumor removal. About 60% of patients are found to have gastric adenocarcinoma, 30% of other abdominal tumors, and about 10% of extra-abdominal tumors, which can be seen in pancreas, gallbladder, uterus, ovarian, intestine, prostate, esophagus, breast or lung tumors.

If there is symmetrical melanin hyperplasia in the neck, armpits, perineum, umbilicus, etc., and the local skin shows keratin hyperplasia, you should seek medical attention as soon as possible to track out whether the patient has gastrointestinal tumors, especially gastric cancer, so as not to delay the disease.

. There are many cases of erythema and erythema on the skin, which may be ordinary dermatitis and eczema at worst, and may be more serious if it is heavier, such as lupus erythematosus (but lupus erythematosus appears in patches, and it is all over the body).

If it begins as an erythematous papule, it is centrifugally enlarged, gradually resolves in the center, and is distributed on the trunk, especially on the buttocks, and pruritus is prominent. This may be an external manifestation of breast cancer and liver cancer.

The other is creeping gyrus erythema, which is wood-grained, mobile and changes rapidly in morphology, and has obvious itching, and is mostly a complication of breast cancer, lung cancer, head and neck malignant tumors, etc.

3. Itchy skin

in

the middle-aged and elderly itching tends to occur in the dry air season, and the typical manifestations are different degrees of itching on the arms, thighs, calves, waist, abdomen, and back, among which the itching of the front and back of the shin of both calves is the most obvious, and the primary skin lesions such as erythema, papules, plaques, and wheals cannot be seen on the skin.

This is due to the fact that the skin is the organ of the human body that has the most extensive contact with the external environment, and is susceptible to the influence of climate and environment. Generally speaking, it takes about two weeks for normal skin to adapt to environmental changes.

As middle-aged and elderly people age, the level of sex hormones will decline to varying degrees, and then the secretion function of the skin will decline, and it will take longer for their skin to adapt to environmental changes. During the dry season, the secretion function of the sebaceous and sweat glands further decreases, resulting in dry skin and itching.

However, it should be noted that the skin is itchy, and we generally don't think it's a serious disease, maybe the skin is too dry. In fact, dry skin can be a serious problem, it could be hormonal disorders, diabetes, liver disease or kidney failure, and the culprit could be a tumor.

External manifestations of some cancers and tumors:

unbearable itching of the skin all over the body, which is a common symptom of many malignant tumors such as Hodgkin's disease, leukemia, myeloma, etc.

4. Herpes zoster skin lesionsJapanese

scholars reported in the medical literature that about 12% of cancer patients will have herpes zoster skin lesions, the elderly are higher, and 18% of patients over 51 years old have herpes zoster with cancer. The most common malignant tumors are lymphatic malignant tumors, and gastric cancer, lung cancer, intestinal cancer, prostate cancer, esophageal cancer, etc.

Herpes zoster with visceral cancer has its own peculiar manifestations. What is the difference between herpes zoster and malignant tumors?

Shingles in general is mostly confined to one side of the body and is immune for life; Herpes with malignant tumors is distributed throughout the body and often recurs. Patients with malignant tumors who develop herpes zoster have a poor prognosis.

5. Multiple geriatric warts skin

warts refer to small growths on the surface of the skin, which can occur in various parts of the body, as small as millet and as large as soybeans, with a smooth or rough surface, shaped like a cap needle, or a stamen, with a normal skin color, or yellowish-white.

Senile warts, technically known as seborrheic keratosis, are benign tumors caused by delayed maturation of keratinocytes and may be a phenomenon of skin aging, becoming more common with age. The cause of senile warts is still unknown.

However, it should be noted that when warts appear suddenly, increase rapidly and are accompanied by itching, there is a high possibility of malignant tumors of internal organs. About 1/2 are gastrointestinal cancers, of which gastric cancer accounts for 1/3. So if this happens, it is best to seek medical attention in time to determine the condition.

6. Migratory phlebitis

Redness, swelling and pain in the vein area are characterized by wandering, which generally relieves after 2~3 weeks, but nodules can form after repeated attacks. The common tumors are pancreatic cancer, especially pancreatic body and pancreatic tail cancer.

The clinical detection rate of pancreatic cancer is low, and migratory thrombophlebitis is an important clue to the diagnosis of this cancer. People over the age of 35 who have migratory thrombophlebitis should suspect pancreatic cancer and be diagnosed and treated in time.

Cancer in the internal organs, skin prophet! If you have these symptoms in your body, you must check them in time so as not to delay your condition! Show it to your friends.
