Definition: Epicorsia is a type of fungal infection that occurs when the skin or mucous membranes are invaded by a fungus, leading to an allergic reaction and inflammation. It's characterized by redness, swelling, and pain in the affected areas. This condition can be caused by conditions such as psoriasis or dermatitis, but it can also occur with other infections like candidiasis. Treatment options include antifungal creams or ointments, antibiotics, and possibly an injection if severe.
