Experts said that long-term skin problems should not be underestimated, in the clinic, “old rotten feet” developed into skin cancer is not uncommon. Shi Dabo lives in Xiangshan. He said, 3 years ago, the outer thigh some itching, scratching on the broken, but also oozing out some yellowish liquid. At that time, look at the skin on the broken ulcer is also the size of a peanut meter, he did not care. But after that, the legs are still itchy, the old man will continue to scratch. A year later, the ulcer expanded to the size of an egg. A month or so ago, the ulcers suddenly got bigger, the size of a child’s palm. Only then did he go to the local hospital. The doctor said he might have to amputate his leg, and he was transferred to the orthopedic department of the city’s Li Huili Hospital. Received by the orthopedic chief physician Dr. Shen. He said that when he was admitted to the hospital, the old man’s leg was badly broken, reaching a diameter of 12 centimeters. The skin had ichthyosis-like lesions that looked like skin cancer. Follow-up blood tests and pathology slides confirmed this judgment, and the old man was diagnosed with squamous cell carcinoma. Fortunately, the old man’s skin cancer was not highly malignant, and the neighboring muscles and bones were not invaded, and there was no metastasis in the distal liver, gallbladder, lungs, etc. He did not need to have his limbs amputated. He did not need to amputate his limbs, as long as he had a skin graft after removing the diseased tissues. According to Dr. Shen, the main reason why the old man suffered from skin cancer was the long-term repeated infections, which stimulated and led to the mutation of the cells. Mao Wei, chief physician of dermatology department of Li Huili Hospital in the city, said that the reasons for inducing skin cancer include sun exposure, repeated infections, trauma, long-term use of pCms with excessive arsenic and long-term contact with some chemical substances. Among them, sun exposure and repeated infections are the most common.
