Why there is lichen on the leg and how to treat it?
The word "lichen" in many causes unpleasant associations. Some people consider this disease to be very contagious, so they are afraid to stroke a dog or a cat that "must" necessarily be the distributors of such a terrible infection, and, of course, they avoid people who are marked with lichen on the leg, arm or other open areas of the body. In fact, in medicine, the term "lichen" is applied to a whole group of skin diseases, among which there are contagious, and there are quite harmless to others, for example, eczema or psoriasis, which can be caused by a common allergy. But how to recognize, what exactly deprive on a leg or a hand at a number of the standing person? How can I determine what kind of rash appeared on my body? What should I do with her and should I immediately run to the doctor? Let's try to understand.
Mechanism of the appearance of the rash
Redness and rash, our skin responds to dozens of irritants - from an allergic reaction to anything before the introduction of pathological microorganisms into the body. The rash may be primary, that is, appearing where there was nothing before, and secondary, formed on the site of the primary in its further development. All diseases, the symptom of which is the appearance on the skin of itchy nodules, spots or papules, is called "lichen."On the leg, arm and other open areas of the body, such rashes give their owners not only physical suffering, but also moral problems, and a rash on the fingers or sole creates difficulties when walking and wearing shoes. There are many kinds of lichen. Not all of them are contagious, but each of them is a danger to the patient. Appearing in one place, the rash can spread over the body, and its incessant itching lead to combs - open wide open for hundreds of germs. In addition, any rash may be a symptom of internal organ disease, which must be identified. Therefore, if there is lichen on the leg or somewhere else, it is necessary to consult a dermatologist to find out the etiology of the rash and its proper treatment.
Before thinking about how to treat lichen on the leg, you need to determine to which species it relates and what is caused. They say that the effectiveness of therapy depends on the correct cause of the disease. For skin rashes, this is especially important, since their etiology is very different. To date, the following types of lichen are diagnosed:
- ringworm, or trichophytosis;
- also ringworm, but already microsporia;
- red flat;
Let's consider them in more detail.
This ailment has other names, such as dermatomycosis, dermatophytosis, scab, ringworm. On the leg or arm, it is rare and in most cases affects the scalp. Previously, this ailment was treated with wax, tar or tar, but beforehand the patient was shaved head. Hence the name - Ringworm. Several types of pathogenic fungi, parasitizing on humans and animals, call it at once. Some parasites settle only where hair extends massively( head, groin, armpits), while others prefer only limbs. It is possible to infect with ringworm from animals, and in these cases the pathogenesis of the disease will be heavier. The second source of the disease is a sick person. The ways of infection are the same as for all mycoses:
- common things( towel, clothes);
- household items;
- close physical contact.
It's important to know what ringworm looks like on your leg. The photo above clearly shows that the rash with this disease has the form of red spots of circular shape. On the edges they are brighter, and in the center are lighter. In the patient, the rash causes severe itching. Sometimes the places of scratching become infected and purulent ulcers are formed.
Light forms of ringworm are treated locally, applying antifungal ointments "Miconazole" or "Clotrimazole" to the lesions and adjacent areas. In severe cases, designate inside the "Griseofulvin".If the source of infection was a pet, you need to vacuum collect all the hair, then carefully wash the room with water and bleach. Things of a sick person need to be washed with fungicidal agents in very hot water.
This is another type of ringworm. It is caused by the fungus Microsporum, which affects any part of the body. It parasitizes on very many animals( dogs, cats, sheep, pigs, horses, rabbits, wild animals).A person becomes infected when they take care of them. You can also catch microsporia from a sick person, using it with some household items, clothing. To do this, it is enough to get hair, wool or flakes from infected skin areas on the skin, which can happen, for example, in a hairdresser's, or when using one with sick things. Microscopy or ringworm on the leg of a person has the form of clearly delineated peeling spots. If the disease has arisen on the head, in the beard, on the eyelashes or eyebrows, in the foci of damage, the hair breaks off, leaving a characteristic "hedgehog"( that's why it is called so-deprive the shearing).Spores of the fungus occupy the remains of hair, covering them with a peeling cover. It's hard to believe, but in our cosmic age, very many, especially urban residents, suffer from microsporia. If in winter such people manage to hide their problems from others, then in the summer on the open areas of the body the rash is clearly visible, for example, herpes on the leg. Treatment of the disease in children or adults is in water procedures using antifungal cleansers. After this, the affected area and around it are applied antifungal ointments with ketoconazole.
This type of disease has another, not so sonorous name - lichen otrubrious. But the people dubbed this rash as a "sun fungus", as it shows well with sunburn. Causes multi-colored lichen one fungus, but it can be in three forms - oval, mycelial and round, passing one into the other. The fungus parasitizes on any parts of the body, but the most common is the multicolored lichen on the leg. The photo clearly shows how the affected skin looks. For an unattached person, dark spots are clearly visible on it, but in the sun they become lighter than neighboring zones. So it turns out, because the fungus breaks the synthesis of melanin, which gives us a tan. Spots "created" by the fungus may eventually fuse or remain solitary. In both cases, peeling is observed on them. This disease is not contagious, because the fungus lives on the skin of almost every one of us. It becomes pathogenic under the following conditions:
- abnormalities in the thyroid gland;
- diseases of the digestive tract;
- weakening of immunity;
- a special composition of sweat;
- prolonged exposure to the sun;
- heavy fizgagruzki;
- increase in blood sugar;
- overdose of corticosteroids;
For accurate diagnosis of varicoloured varieties, use a Balzer test, a Wood lamp, skin scrapes.
Treatment is carried out with antifungal cleansers and ointments, for example, Nizoral, Fluconazole.
This disease is awarded to us by all the known herpes virus type 3, or chicken pox. In children who have recovered from it, the virus moves to nerve cells and sleeps there for decades. Under certain circumstances, he wakes up and exits through the axons. The exact mechanism of the process has not yet been clarified. Herpes can appear anywhere in the body, depending on where its axons will go. Shingles on the leg or other parts of the body initially look like a cluster of pink, slightly swollen spots. Three, at most five days, they turn into erythematous papules, and a day or two into bubbles with a clear liquid. In the future, the bubbles dry up, leaving a crust behind them."Wake up" the virus are capable of:
- taking antibiotics, cytostatics, all drugs that depress the immune system;
- organ transplant;
- malignant tumors;
- bone marrow transplantation;
- age changes( more often people over 50 years old);
Before the appearance of rashes, patients usually experience soreness and itching in those places where herpes will pop out, as well as some malaise. Her shingles on her leg can walk for about a month on her own, but to avoid complications, doctors recommend taking antiviral drugs, and with severe pain analgesics. A preventive measure against this disease is vaccination.
This disease is non-contagious and appears as a complication of the common cold or flu. While it is not exactly determined what or who causes pink lichen. On the leg, arm or trunk( everywhere along the lines of the Langer) it looks like a group of pink oval spots with peeling in the center. The first manifestations in a person can begin either during the cold or after recovery. Treatment of pink lichen does not require, as it passes by itself, leaving no traces. Only if the patient experiences an intolerable itch, doctors attribute antihistamines and antipruritic ointments.
This is one of the most common and most unpleasant chronic skin diseases - psoriasis. He does not pose a danger to others, but a sick person brings a lot of trouble. Some sufferers with scaly lichen even need the help of a psychologist, so they lose self-esteem and quality of life because of this ailment.

In these places exudate is constantly allocated, which is why deprive and call it wet. When drying up, erosions form yellowish-brown crusts, but new acne can appear nearby, and the process repeats. In a chronic form in place of erosion, the skin becomes denser, begins to peel off. The chronic course of the disease is again replaced by a sharp one, giving the patient physical suffering - itching, burning, high soreness of the affected areas of the skin.
