What is the disease that causes dampness and itching at the base of a man’s thighs?

When the body feels very itchy, it is very uncomfortable. When the skin is itchy, the first thing people think of is to scratch it with their hands. Indeed, many itching symptoms can be solved in this way, but this is only an occasional itching. If a certain part of the body is itchy for a long time, it is not certain whether scratching can make the itching go away, but the most important thing is that it is easy to scratch the skin. So, what is the disease of wet and itchy thigh roots in men?

Causes

It is often caused by Epidermophyton floccosum, Trichophyton barbae, and Trichophyton rubrum. Sometimes, Candida albicans also invades the groin area and presents as erythematous and scaly patches with papules and urticaria on the edges.

This disease is prone to occur in warm and humid seasons, especially men with excessive sweating. Special occupations such as car drivers and people 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 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 scaling on it, and gradually expands and spreads to the surrounding area, with clear boundaries, papules, blisters, scabs, and itching on it. The central part can heal on its own, with pigmentation or scaling. Over time, the local skin will become infiltrated and thickened, often with itching. In severe cases, it often expands to the inner side of the thigh, perineum or around the anus, and its lower edge is mostly clear. Sometimes it can also affect the scrotum, the root of the penis, etc.

Diagnosis

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

Differential diagnosis

It should be distinguished from erythritis, seborrheic dermatitis, proliferative acne, erosive psoriasis, etc.

treatment

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

Treatment of tinea corporis. Since the skin of the pubic region is relatively delicate, care should be taken not to use overly irritating lotions to avoid irritating the skin. Generally, compound resorcinol lotion or 1% econazole or clotrimazole cream can be used. 2% miconazole, bifonazole, ketoconazole, sertaconazole, butenafine, and terbinafine cream can also be used.

Oral griseofulvin has a certain effect, but it is easy to relapse after stopping the drug, so it is not suitable for use. Fluconazole, itraconazole, terbinafine, etc. can be used for a short period of time.
