Moth-Eaten Pattern of Alopecia in Lichen Planopilaris

An 18-year-old male with Type 1 Diabetes Mellitus presented with a moth-eaten pattern of alopecia, characterized by multiple small, ill-defined patches of hair loss on the scalp. Clinical, trichoscopic, and histopathological evaluations confirmed the diagnosis of Lichen Planopilaris (LPP), an inflammatory disorder leading to scarring alopecia. The patient was treated with methotrexate due to his diabetes, as other treatments could affect blood sugar levels. Early diagnosis and treatment of LPP are crucial to prevent permanent hair loss. The study highlights the importance of differentiating LPP from other causes of moth-eaten alopecia for appropriate management.
