What are Wickham striae?

• A. Crusty lesions on elbows
• B. Fine white lines on lesions
• C. Red spots around the mouth
• D. Scaling rashes on the trunk

Answer: (B)

Wickham striae refer to the fine white lines that can be observed on the surface of certain types of lesions, particularly in conditions such as lichen planus. These striae are often described as being lace-like or reticular in appearance and can be found on the surface of the lesions as well as on adjacent normal skin. The presence of these striae is a key feature that helps differentiate lichen planus from other dermatological conditions. Recognizing Wickham striae is essential for accurate diagnosis, as they provide important clinical insight into the nature of the skin condition being examined.
