White spots on the inner palm

White spots on the palms are usually caused by conditions such as nevus depigmentosus, dyshidrotic eczema, or tinea manuum. In such cases, it is important to seek medical evaluation promptly and receive treatment based on the underlying cause under a doctor's guidance. Specific analyses are as follows:

1. Nevus Depigmentosus

Nevus depigmentosus is a congenital skin condition characterized by hypopigmented patches, often associated with genetic factors. It typically causes localized white patches on the skin without discomfort and generally does not require specific treatment.

2. Dyshidrotic Eczema

Dyshidrotic eczema commonly occurs during summer and leads to recurrent blisters or white spots on the hands, accompanied by itching and pain. Patients should follow medical advice to apply topical medications such as mometasone furoate cream or calamine lotion to relieve symptoms.

3. Tinea Manuum

Tinea manuum is a contagious fungal infection of the hands that causes blisters or white patches with scaling on the surface, often accompanied by itching. Under medical supervision, patients should use topical antifungal agents such as compound clotrimazole cream or ketoconazole cream to improve symptoms.

In addition to the common causes mentioned above, other possible factors include pityriasis alba, vitiligo, or Marshall syndrome. Individuals experiencing abnormal skin changes should seek timely medical attention to avoid delays in diagnosis and treatment.
