Discoid lupus erythematosus, commonly found on exposed areas such as the face and ears. It presents as red patches or plaques with a sticky, flaky surface that is not easily removed. It is usually not itchy. Definitive diagnosis depends on pathological biopsy. For treatment, the first thing is to have confidence. Lupus erythematosus is treatable, but the course of the disease is long. In discoid lupus erythematosus, if there is no visceral damage, it can be treated with oral hydroxychloroquine and topical tacrolimus ointment, or a medium-acting hormone ointment, such as Eloson. For other facial diseases, we do try not to use hormones, but for lupus erythematosus, if the effect with other drugs is not good, you can use them, but not for too long. It also depends on your reaction after using it. In addition, you should pay attention to sun protection and watch yourself for the appearance of other symptoms, such as mouth ulcers, joint pain, sun allergy, etc. Every six months, you should monitor routine laboratory tests and immunological indicators, including blood and urine routine, liver and kidney function, ANA, dsDNA, ENA, chest X-ray, electrocardiogram, cardiac ultrasound, etc. Because lupus erythematosus is a spectrum of diseases, some patients will evolve and become systemic lupus erythematosus.
