A 79-year-old man has had blue-purple patches on his feet for more than two years, not only on the soles of his feet, but also on his ankles and toes. I didn't actively treat it because it didn't hurt, but I was worried that the patch would infect my family because it was getting bigger and bigger and the surface was prominent. After examination, he was diagnosed as a typical Kaposi sarcoma. Ke Weili, director of the dermatology department of Hong Kong and China Hospital, pointed out that Kaposi's sarcoma is mostly related to herpes-like virus type 8, which mostly occurs in elderly men. Patients with Kaposi's sarcoma have a slow course of disease and are easily overlooked. Because of the wide coverage of the lesion, it can not be removed, so radiotherapy is used. Director Ke Weili said that Kaposi's sarcoma mostly occurred in the lower limbs, mostly in the feet or ankles. However, due to the slow development of the course of disease and asymptomatic, it may invade the lymphatic system and even internal organs for a long time. In addition, although AIDS patients may have similar symptoms, if they are typical patients with Kaposi's sarcoma, it has nothing to do with AIDS. Radiotherapy can effectively control Bohemian sarcoma. Clinically, if radiation is used to treat typical Kaposi's sarcoma, usually after three weeks of treatment, the prominent lump can be obviously eliminated, and the plaque changes from blue-purple to brown. Zhong Nana, the attending physician of radiation oncology department of China-Hong Kong Hospital, pointed out that at this time, the skin virus has been gradually killed, and patients need not worry too much. Radiotherapy can effectively control Bose sarcoma and help patients find back their quality of life. If there are unknown plaques on the limbs, you should seek medical examination as soon as possible. Typical Kaposi's sarcoma has a slow course and is easily overlooked by patients. Therefore, if you find unexplained plaques on the limbs, you should seek the assistance of a dermatologist as soon as possible. Director Ke Weili appealed that if the typical Kaposi sarcoma is small, it can still be surgically removed, but if the area is too large or even invades the internal organs, chemotherapy will be taken at that time, and its seriousness cannot be ignored.
