Introduction

If the affected area is the skin (such as hands, feet, or trunk) and accompanied by symptoms like itching, erythema, and scaling, it is most likely a superficial fungal infection (e.g., tinea manuum, tinea pedis, or tinea corporis). These infections are confined to the superficial layers of the skin, where fungal hyphae and spores proliferate within the stratum corneum. Prompt treatment with topical antifungal agents (such as clotrimazole or terbinafine) usually effectively controls the condition and relieves discomfort.

Under normal circumstances, the presence of fungal hyphae and spores indicates a fungal infection in the tested sample, which may cause symptoms related to the skin, mucous membranes, or other affected areas. If concerned, it is recommended to seek medical advice promptly. The detailed analysis is as follows:

If the tested site is the skin (such as hands, feet, or trunk) and accompanied by symptoms like itching, redness, or scaling, it is likely a superficial fungal infection (e.g., athlete's foot, tinea corporis). These infections are confined to the outer layers of the skin, where fungal hyphae and spores proliferate in the stratum corneum. Timely application of topical antifungal medications (such as clotrimazole or terbinafine) usually effectively controls the condition and relieves discomfort.

If the tested site is a mucous membrane (such as the oral cavity or vagina) or deep tissues, or if symptoms such as fever, pain, or tissue swelling are present, it may indicate a deep fungal infection. These infections are relatively complex, with fungi potentially invading beneath the mucosa or into internal organs. Further diagnostic tests are required to determine the extent of infection. Treatment typically involves oral or intravenous antifungal drugs, requires a longer duration, and necessitates close monitoring of the body's response.

After receiving test results, prompt medical consultation is necessary to confirm the site and type of infection. Follow the doctor’s instructions strictly regarding medication—do not discontinue or adjust dosage without guidance. Maintain good personal hygiene during treatment, avoid close contact with others to prevent cross-infection, and schedule regular follow-up visits to evaluate treatment effectiveness.

What is the fungal infection causing dry, flaky skin?

In general, flaky skin rashes are often caused by fungal infections or skin inflammation. Common types include tinea corporis (ringworm of the body), tinea cruris (jock itch), tinea manuum (hand fungus), tinea pedis (athlete's foot), and pityriasis versicolor. Although symptoms may vary, these conditions can all be accompanied by dry, flaking skin and require targeted treatment. It is important to maintain personal hygiene, wash clothes separately, and expose them to sunlight for disinfection. Avoid scratching affected areas to prevent the spread of infection.

What should a pregnant woman do if she has many small blisters on her hands that are extremely itchy?

In general, if a pregnant woman develops many small blisters on her hands accompanied by intense itching, it may be due to hormonal changes during pregnancy causing skin sensitivity, exposure to irritants, dyshidrotic eczema, hand fungus (tinea manuum), or pruritic urticarial papules and plaques of pregnancy (PUPPP). It is recommended to seek medical attention promptly, identify the underlying cause, and follow a safe treatment plan under a doctor's guidance.

Why is an elderly person's hand so itchy that it has become raw from scratching?

In general, elderly individuals may develop severe skin damage from scratching due to dryness and aging skin, exposure to irritants, eczema, hand fungus (tinea manuum), diabetic peripheral neuropathy, or other causes. It is recommended to seek medical attention promptly, identify the underlying cause, and undergo symptomatic treatment under a doctor's guidance. In daily care, trim the elderly person's fingernails evenly to prevent sharp nails from worsening skin injuries caused by scratching.
