The Vietnamese word "bạch biến" refers to a medical condition known as vitiligo. It is characterized by the loss of skin pigment, leading to white patches on various parts of the body. This condition occurs when the cells that produce melanin, the pigment responsible for skin color, are destroyed or stop functioning.
In a more detailed context, you might discuss the psychological or social implications of having "bạch biến," as it can affect a person's self-esteem and social interactions.
In general usage, "bạch" means "white" and "biến" means "change" or "transform." So, "bạch biến" literally translates to "white change," which describes the transformation of skin color in the affected areas.
Understanding "bạch biến" is essential for discussing skin conditions in Vietnamese, particularly in medical settings.
