Why do girls' inner thighs itch?

Body itching is very common. Sometimes it will go away by scratching it with your hands. However, if it is caused by insect bites, for example, the itching will not stop until the body has completely digested these toxins. In addition, some diseases can also cause itching in the human body, such as common urticaria and so on. So, what is the disease that causes itching on the inner thighs of girls?

All annular or semi-annular skin lesions caused by pathogenic fungi invading the inner side of the groin are collectively called tinea cruris, which is actually a special type of tinea corporis in the pubic and femoral areas.

Causes

It is often caused by Epidermophyton floccosum, Trichophyton mentagrophytes, Trichophyton rubrum, etc. Sometimes, Candida albicans also invades the groin area and presents as erythematous desquamative patches with papulovesicles on the edges.

This disease is prone to occur in warm and humid seasons, and men with excessive sweating are particularly susceptible to it. People in special occupations, such as car drivers and those who sit for long periods of time, are also prone to the disease.

Clinical manifestations

It often occurs on the skin of the thigh opposite the scrotum, on one side or both sides, and is mostly annular or semi-annular patches. Initially, a small patch of erythema appears on the inner side of the upper thigh, with desquamation on it, and gradually expands and spreads to the surrounding area with clear boundaries, and there are papules, blisters, scabs and itching on it. The central part can heal itself, with pigmentation or desquamation. Over time, the local skin will become infiltrated, thickened and lichenified, often accompanied by itching. In severe cases, it often extends to the inner thigh, perineum or around the anus, and the lower edge is usually clear. Sometimes it can affect the scrotum, base of the penis, etc.

diagnosis

The diagnosis can be confirmed based on clinical manifestations, skin lesion morphology and mycological examination.

Differential Diagnosis

It should be differentiated from erythrasma, seborrheic dermatitis, vegetative pemphigus, erosive psoriasis, etc.

treat

Obese people should take a bath frequently and apply face powder, etc.

Treat tinea corporis. Because the skin of the pubic area is more delicate, care should be taken not to use overly irritating lotions to avoid skin irritation. Generally, compound resorcinol ointment or 1% econazole or clotrimazole cream, 2% miconazole, bifonazole, ketoconazole, sertaconazole, butenafine, and terbinafine cream can also be used.

Oral griseofulvin has a certain therapeutic effect, but it is easy to relapse after stopping the drug and is not suitable for use. Fluconazole, itraconazole, terbinafine, etc. can be used in the short term.
