There is no great risk of removal of sarcoid nevus, a soft fibroid of the skin, which is a sarcoid. Most of them occur in the upper lid, neck and groin, and some of them appear to be more slender. Some of these nevi are slender and can be removed with carbon dioxide. However, some of them are prone to recurrence after puncturing, and the nevus can be removed by puncturing 1-2 times again after recurrence, and there is usually no risk of deterioration. For larger nevi without pigmentation, some of them are more rounded or protruding nevi on the skin surface, and their recurrence of malignant transformation is lower, and they can be removed surgically. In general, larger nevi are treated by surgical excision, while smaller nevi are treated with CO2 laser.
