Pediatric Lichen Planopilaris: Clinicopathologic Study of Four New Cases and a Review of the Literature

The study examined four pediatric cases of Lichen Planopilaris (LPP) in patients aged 13 to 16 years, highlighting its rarity and potential for misdiagnosis as alopecia areata. Common findings included perifollicular scale, scarring, and histopathologic evidence of perifollicular interface and fibrosis. Treatments with topical or intralesional steroids and minocycline were used, with good long-term responses in two patients. The study emphasized the importance of biopsying active inflammation for accurate diagnosis and supported corticosteroids as a first-line treatment.
