Introduction

Tinea manuum with vesicles is mainly caused by damp environments, compromised skin barriers, immune system abnormalities, fungal infections, diabetes, and other factors. Prolonged exposure of the hands to moist conditions, such as frequent hand washing, working with gloves, or engaging in water-related activities, may increase the risk of infection leading to tinea manuum. It is important to keep the hands dry, change to clean and dry gloves frequently, and avoid prolonged immersion in water.

Normally, vesicular tinea manuum (hand fungus) is mainly caused by damp environments, damaged skin barriers, immune system abnormalities, fungal infections, diabetes, and other factors. If discomfort occurs, please seek medical attention promptly. Detailed explanations are as follows:

1. Damp Environment

Prolonged exposure of the hands to moist environments, such as frequent hand washing, working with gloves, or engaging in water-related activities, may increase the risk of infection, leading to hand癣. Keep hands dry, change to clean and dry gloves frequently, and avoid prolonged immersion in water.

2. Damaged Skin Barrier

When the skin barrier is compromised, fungi can more easily penetrate the skin surface and enter deeper tissues, causing hand fungus. Protect damaged skin from further injury. Use healing creams containing ingredients such as hyaluronic acid and vitamin E to promote skin recovery.

3. Immune System Abnormalities

Immune system abnormalities may involve multiple factors, such as heredity and environmental influences. When immune function weakens, the skin's defense against fungal infections decreases, making infections and vesicular tinea manuum more likely. General discomfort and fever might also occur as immune responses. Under the guidance of a specialist physician, medications such as transfer factor oral solution, tacrolimus capsules, and human immunoglobulin may be used for treatment.

4. Fungal Infection

Vesicular tinea manuum is primarily caused by fungal infections from the dermatophyte group, such as Trichophyton rubrum and Trichophyton mentagrophytes. These fungi can invade the stratum corneum of the skin and proliferate within it, causing inflammatory reactions and resulting in vesicular tinea manuum, which may present symptoms such as erosion and exudation. Follow medical advice to use antifungal medications such as ketoconazole cream, terbinafine hydrochloride cream, and miconazole nitrate cream.

5. Diabetes

Obesity and excessive intake of high-sugar foods can trigger diabetes. Patients with diabetes, due to a hyperglycemic state, experience reduced immune function, increasing the risk of fungal infections, especially hand fungus. Symptoms such as thirst and polydipsia may also appear. It is recommended to follow medical guidance for treatment with medications such as insulin degludec injection, acarbose capsules, and glimepiride tablets.

In daily life, avoid sharing personal items with others, such as nail clippers, socks and shoes, bathtubs, and towels, to reduce the risk of cross-infection.
