　　Tinea cruris is a fungal skin infection commonly affecting the inner thighs, buttocks, and areas surrounding the genitals. Main symptoms include itching, erythema, papules and vesicles, scaling, and skin erosion. If any abnormalities occur, timely medical consultation is recommended. The following is a detailed analysis:

　　1. Itching: The infected area in tinea cruris is often accompanied by intense itching. This occurs because the skin inflammation caused by the fungal infection stimulates nerve endings, leading to itchiness. Patients may feel compelled to scratch, which can further aggravate skin damage and promote the spread of infection.

　　2. Erythema: In the early stages of tinea cruris, red patches appear in the groin, perineal region, perianal area, or buttocks, which may be unilateral or bilateral. As the condition progresses, these patches gradually expand outward, forming annular or semicircular lesions with well-defined borders and prominent inflammatory edges.

　　3. Papules and vesicles: As the disease advances, papules and vesicles may develop along the edges of the erythematous patches. Papules are small, firm, raised lesions that are similar in color to the surrounding skin, while vesicles are small fluid-filled blisters. These skin lesions may increase patient discomfort.

　　4. Scaling: On top of the erythematous areas, patients with tinea cruris may experience skin scaling. The scales may appear white, silvery-white, or grayish-brown and are typically accompanied by itching and redness.

　　5. Skin erosion: If tinea cruris is not treated promptly, the affected skin may develop erosions. Erosion refers to the breakdown and exudation of the superficial skin layer, which may be associated with pain, redness, and swelling.

　　Patients may use antifungal medications such as miconazole nitrate cream, econazole nitrate cream, or ketoconazole cream under the guidance of a physician.
