How is the rash of lichen planus different from that of most other common rashes?
Lichen planus can be distinguished from eczema, psoriasis, and other common rashes purely on the basis of its clinical appearance in that lesions are small bumps or aggregations of bumps that are flat-topped, shiny, polygonal, purple to grey in color, tend to occur at the wrists and elbows and ankles, and on close examination contain thin white lines called Wickham's striae. When lichen planus involves the oral tissues, such as the lips or cheeks, these white filmy lines are easy to detect. It is not unusual for lichen planus to appear at sites of trauma, especially along lines of scratches (excoriations).
What are lichen planus symptoms and signs?
Lichen planus itches with an intensity that varies in different people from mild to severe.
The onset of lichen planus can be sudden or gradual. The first attack may last for weeks or months, and recurrences may happen for years. The bumps at first are 2 mm-4 mm in diameter, with angular borders and a violet color. An excess of pigment (hyperpigmentation) may develop in the affected skin as the lesions persist. Rarely, a patchy, scarring bald (alopecia) area on the scalp occurs.
