Oral Lichen Planus Preceding Concomitant Lichen Planopilaris

The document described a case of a patient with concomitant oral lichen planus (OLP) and lichen planopilaris (LPP), highlighting that this was the first reported instance of OLP preceding the onset of LPP. OLP is an immune-mediated disorder affecting the mucous membranes of the mouth, while LPP is a variant that affects the scalp, leading to hair loss. The association between these two conditions had been noted before, but information on their simultaneous or sequential presentation was limited.
