👉 Tan infection, also known as tan ulcer or tan ulcer syndrome, is a rare and often painful skin condition characterized by the formation of deep, red, and sometimes ulcerated lesions, typically on the legs, feet, or buttocks. The exact cause of tan infection remains unclear, but it is believed to result from a combination of factors, including bacterial infections (often Staphylococcus aureus), fungal infections, or even autoimmune responses. When bacteria or fungi invade the skin, they can trigger an inflammatory reaction, leading to the characteristic lesions. These ulcers can be painful and may cause significant discomfort, especially when pressure is applied. Treatment usually involves antibiotics for bacterial infections, antifungal medications for fungal infections, and sometimes corticosteroids to reduce inflammation. In severe cases, surgical intervention might be necessary to drain abscesses or remove infected tissue.
