White spots on the stomach may be lichen planus or senile leukoplakia. Lichen planus is caused by a fungal infection and is most often associated with moist, sweaty skin, or with medical systemic diseases such as anemia or diabetes. It manifests as white depigmented patches with furfuraceous flaking on the surface and varying degrees of itching. Treatment can be topical anti-fungal drugs, such as terbinafine cream, bifenazole cream, etc.. Normally, it is necessary to avoid damp and sweaty skin and actively treat the primary disease. Age-related white spots belong to a manifestation of skin aging, manifesting as white spots of bean grains, with clear boundaries, smooth surface, no dander, no self-conscious symptoms, and no need for treatment.
