In a patient with lichen planus, which manifestation is characterized by Wickham striae?

• A. Lesions on the skin
• B. Oral lesions
• C. Gingival lesions
• D. Keratinized lesions

Answer: (B)

The manifestation characterized by Wickham striae in a patient with lichen planus is oral lesions. Wickham striae are fine, white lines or streaks seen on the surfaces of oral lichen planus lesions. These striae can often be observed within the lesions, which may appear as white patches or reticular patterns on the mucosal surfaces.

Oral lichen planus is a common presentation, and it can present with varying degrees of pain or discomfort. The distinctive appearance of Wickham striae is a helpful diagnostic feature that sets these lesions apart from other conditions affecting the oral mucosa.

While skin lesions and gingival lesions can also occur in lichen planus, they do not typically exhibit the same characteristic striae. Keratinized lesions may also occur, but the presence of Wickham striae is specifically noted in the context of oral lesions. Thus, selecting oral lesions as the manifestation associated with Wickham striae highlights an important aspect of identifying and managing lichen planus effectively.
