自1975年5月至1977年3月,我们应用深低温液氮冷冻治疗皮肤肿瘤52例,其中血管瘤47例,基底细胞癌3例,黑色素瘤(早期恶性)和乳房外柏哲氏病各1例,效果较为满意。治疗方法:按皮损大小选择不同探头,置于损害表面加压接触,然后降温。从探头与组织紧密粘着出现白霜时,开始计算时间。经一次或多次冻～融。冷冻剂量:血管瘤1～11/2分钟,1～2次;恶性肿瘤2分钟,2次或2次以上。临床所见及疗效:冷冻后,皮肤局部组织有明显水肿、大疱、血疱。随冷冻深度而异,3～4天内达到高峰。出现水疱时,可抽
From May 1975 to March 1977, we applied cryogenic cryogenic liquid nitrogen cryotherapy to treat 52 cases of skin tumors, including 47 cases of hemangiomas, 3 cases of basal cell carcinoma, melanoma (early malignancy), and extrapulmonary Beria disease. In 1 case, the effect was satisfactory. Treatment method: Select different probes according to skin lesion size, put pressure on the damage surface, and then cool down. Calculate the time from when the probe sticks to the tissue and appears white frost. After one or more freeze-thaw. Frozen dose: Hemangiomas 1 to 1 1/2 minutes, 1 to 2 times; malignant tumors 2 minutes, 2 or more times. Clinical findings and efficacy: After freezing, the skin had obvious edema, bullae, and blood stasis. It varies with the depth of freezing and peaks within 3 to 4 days. When there is water, it can be pumped
