Severe athlete's foot with cracked, peeling skin between the toes

Severe foot cracking, peeling, and ulceration may be related to physiological factors and can be relieved through proper moisturizing. It could also result from conditions such as athlete's foot (tinea pedis) or contact dermatitis, which require appropriate medical treatment. The specific analysis is as follows:

1. Physiological Factors

If foot care is neglected in daily life, the skin on the feet may become dehydrated and excessively dry, leading to peeling and ulceration. No special treatment is required; symptoms usually improve with proper foot moisturization. Detailed explanation is as follows:

2. Pathological Factors

1) Athlete's Foot (Tinea Pedis)

This is a fungal infection of the skin on the feet that causes localized skin damage. Under the stimulation of the fungus, the feet may develop ulceration, peeling, and cracking. Active treatment under medical guidance is necessary, using antifungal medications such as miconazole nitrate cream, compound ketoconazole ointment, or econazole nitrate cream.

2) Contact Dermatitis

A common inflammatory skin condition in clinical practice, contact dermatitis occurs when exposure to exogenous substances triggers an inflammatory reaction in the feet. Inflammation may lead to symptoms such as ulceration, peeling, and itching. Treatment should be conducted under a doctor’s supervision using medications like calamine lotion, desloratadine citrate tablets, and fluorocinonide acetate cream to promote recovery.

In addition to the above causes, similar symptoms may also arise from eczema, chilblains, diabetes, and other conditions. If discomfort occurs, timely medical evaluation and proper treatment under professional guidance are recommended to facilitate recovery.
