In our country, the pathogen that causes tinea cruris is mainly Trichophyton rubrum and Gypsum-like Trichophyton rubrum, Epidermophyton flocculent epidermidis and a few Candida albicans.
The main symptom is obvious local itching. The disease is prone to recurrence. Mostly due to contact with patients with ringworm or through cats, dogs and other infections, or through clothing and utensils and indirectly infected, or first suffered from tinea pedis, due to scratching and spreading the contagion. Summer season, the climate is hot and humid, the human body sweating, especially within the stock, such as not timely bathing, or wearing tight underwear a large amount of sweat can not evaporate, it is easy to get this disease. In addition, patients suffering from diabetes, excessive leukorrhea, etc., as well as long-term oral or local application of a large number of broad-spectrum antibiotics or corticosteroids, are also prone to ringworm. In terms of incidence, it is mainly young people, more men than women. The disease occurs in the summer, the climate is humid or hot often make the condition worse, winter relief or recovery.
Tinea cruris is a skin disease that occurs in the femur, and can sometimes involve the perineum, mons pubis, perianal area, buttocks, scrotal folds, etc. The itching is intense, and due to scratching, patients can develop dermatitis, tinea versicolor changes or secondary infections.
The rash of tinea cruris is characterized by:
(1) Tinea cruris begins as a red spot with clear, slightly elevated margins, gradually enlarges with falling flakes, and gradually changes from red to brown or skin color.
(2) The center of the lesion gradually heals itself and develops around it, the edge of the erythema is more obviously inflamed, and there can be rashes, blisters, scabs, and even vesicles on it, forming a ring.
(3) After healing, it leaves temporary hyperpigmentation and severe itching symptoms.
To make a clear diagnosis of ringworm, first of all, you need to find an experienced specialist physician, who can easily make a clear diagnosis based on medical history, symptoms, signs and laboratory tests. Ringworm is a mold infection, generally speaking, make a direct microscopic examination of the falling flakes, that is, take the edge of the skin lesions at the small pieces of scales, placed on a glass plate, drop into a little potassium hydroxide solution, so that the keratin dissolves, and then placed under the microscope, to observe whether there is a fungal hyphae, can be a clear diagnosis. Of course, if you have the conditions, you can also rely on the culture of the fungus to make a clearer diagnosis.
It is not difficult to diagnose tinea cruris, but it should be carefully identified with some skin diseases, otherwise it is difficult to make the treatment to the target. The main skin diseases easily confused with ringworm are:
(1) seborrheic dermatitis: sometimes also invades the pubic and femoral areas, the rash is a light red spot, there is flaking, and some are ring-shaped, the border is clear, but direct microscopic examination of the fungus is negative.
(2)Erythroderma: a skin disease caused by a kind of rod-shaped bacillus, commonly found in the armpit, femur, etc., the skin of the lesion area is brick red, the edge has no inflammatory ring, not itchy, direct microscopic examination of the fungus is negative.
(3) psoriasis: commonly known as psoriasis, can invade the femur, manifested as ring or plaque-like erythema, usually with thick scales on the surface, and other parts of the body can have the same rash.
The ringworm is most common on the buttocks and upper inner thighs, but it also often violates the penis. It starts as a small mound (pimple), itches, and then expands to form a round or polygonal lesion with a ring-like raised edge and a flat center, and is often flaky. It causes concern that it is a sexually transmitted disease (STD). This apprehension is not necessary.
The ringworm is a more stubborn disease, very easy to recur, sensitive to many drugs, but the treatment is over for a certain period of time can still recur. Generally, external treatment is the mainstay and internal treatment is not needed; however, internal treatment can be added to those who are stubborn and generalized. Commonly used in the treatment of jock itch medicine:
(1)Compound leizosin solution, for the hospital internal preparation, stimulation is small, the effect is rapid, 1 ~ 2 times a day external use, even 10 days can achieve clinical recovery.
(2)Compound Dakinin, produced by Xi'an Janssen Pharmaceutical Factory, has a fast effect and good itching relief.
(3)1% Clotrimazole, Clotrimazole Cream, 1% Econazole Cream and so on. I recommend clotrimazole.
The skin at the penis is thin and tender, and the treatment should not use drugs that are too stimulating, such as long time treatment is not cured, or the area is large, the onset of extensive, can be taken internally Spironolactone 200mg, once a day, for 5 days.
Clinical evidence suggests that the external washing of Chinese herbs is one of the effective methods of treating ringworm, which is fast-acting, good at stopping itching, and is not easy to recur after the cure. Experiments have confirmed that Chinese herbs such as cypress, Cangzhu, Baibu, Qingmu Xiang, Hibiscus mutabilis, Ai Ye, pepper, Dijianzi, bitter ginseng, soil rhubarb, thick Park, etc. have a good antifungal effect.

(2) Change and wash your underwear often, and keep your vulva clean and wash and dry your clothes often.
(3) Reduce sweating and promote evaporative action at the root of the femur. Try to keep dry and wear loose fitting underwear.
