Leukoderma is a skin disorder characterized by:

• A. Dark patches
• B. Light patches
• C. Brown patches
• D. Red patches

Answer: (B)

Leukoderma denotes loss of pigment in the skin, resulting in lighter patches that stand out against surrounding skin. The root leuko- means white, so this term specifically describes depigmented or hypopigmented areas rather than darker areas. This is different from dark or brown patches, which reflect increased pigment, and red patches, which indicate inflammation or increased blood flow. In practice, leukoderma can occur when melanocytes are damaged or absent in patches, as seen in conditions like vitiligo, leading to clearly lighter skin patches.
