Mossy leukoplakia usually refers to mossy vulvar leukoplakia, which is usually more serious, but the exact severity should be determined by the progression of the disease, as well as the extent of the disease and the history of the disease involved. If the diagnosis of mossy leukoplakia is confirmed, if the extent of the disease is relatively small, if it does not involve the surrounding tissues, and if the history of the disease is relatively short, and if the disease progresses slowly, it is not considered to be particularly serious, and the disease can be effectively controlled with active treatment. Some patients with mossy leukoplakia have a wider extension, larger lesion area and relatively longer history of the disease, indicating that the condition is more serious. These patients may have spasmodic narrowing of the vaginal opening, itching in the pubic area, etc., and it may affect sleep and normal urination. At present, the detection of mossy white spots, should be targeted as soon as possible to avoid the gradual increase in the scope of skin lesions; during the treatment period should keep the vulva dry and clean, to avoid cross-infection, and if there is any discomfort to consult a doctor in a timely manner.
