Abstract
- Bichloroacetic acid(BCA), one of the chloroacetic acids, is an effective tissue cauterant when used in high concentration. In dermatologic surgery, BCA, in the form of 100% solution, has been used to treat xanthelasma, sebaceous hyperplasia, verrucae, hard and soft corn, seborrheic keratosis, ingrowing nail, cysts. The cauterization with BCA 100% solution can be used with a simpler technique than the surgical excision or electrical cauterization, without complicated appliance such as LASER generators, so the dermatologic surgical technique - BCA chemical cauterization, topical treatment - can be selected as a treatment of choice for many dermatologic conditions in outpatient offices. BCA destroys the barrier function of the epidermis and penetrates deeply through the papillary dermis and then creates the effect in the papillary dermis and reticular dermis. As a result, regeneration of new dermal collagens and a new epidermis occurs. This pharmacologic effect of BCA makes 100% solution of BCA to be used in the treatment of xanthelasma, pigmented nevi, acne scars with good clinical outcomes.
