Definition

1. Noun (Danh từ):

Notes on Meaning

• Medical Specificity: "Bạch biến" is a specific dermatological condition (vitiligo). It should not be confused with other conditions causing hypopigmentation like albinism (bạch tạng) or post-inflammatory hypopigmentation.
• Non-Compound Usage: The core meaning resides in the term "bạch biến" itself. Common usage often includes "bệnh" (disease) as in "bệnh bạch biến," but the target term for explanation remains the precise two-word noun "bạch biến."
