Patient: The onset of the disease began in 2000 and was well for a few months, the onset of the heat was red and wanted to be larger than a bean, later it turned white, just after a bath it was a little itchy and used Dink’s cream for a few times, but it did not stop. Patient: I was treated at Jiangcheng Hospital with Chinese herbal medicine, but it didn’t work at all, the doctor said I would recover after 2 courses of treatment, but I didn’t feel comfortable doing three courses of treatment and I didn’t see any effect. The dermatology department of Shanghai Long March Hospital, Gu Julin: Tinea Versicolor is caused by fungus – Malassezia infection, oral medicine can choose Itraconazole, but there is still a possibility of recurrence. The most important thing to remember is that it is not easy to get rid of the fungus, but it is difficult to get rid of it permanently. The skin pigmentation is difficult to restore to normal because the melanocytes in the lesions have been damaged.3. To prevent recurrence, wash with 2% ketoconazole lotion once a week. You can come and see us when it is convenient and do some examination properly.
