Lichen Psoriasis

📋Overview

Lichen Psoriasis is often considered a legacy designation for cases where patients present with characteristics of two distinct chronic inflammatory skin diseases. While modern clinical practice typically classifies lichen planus and psoriasis as separate entities with unique pathophysiological pathways, clinicians may occasionally observe an overlap syndrome where both conditions coexist.

Both conditions are characterized by immune-mediated responses that affect the skin and mucous membranes, though they generally differ in their specific clinical presentation and underlying mechanisms. Identifying the specific nature of the inflammatory response is essential for distinguishing between these two chronic dermatological concerns.
