The diagnosis was based on clinical evaluation, histopathology and trichoscopy. Squamous cell carcinoma developed within the hairless area after 18 years of evolution.CONCLUSIONIt is necessary to consider the association between lichen planopilaris and squamous cell carcinoma and to ensure a close follow-up of LPP patients, especially when there is a long history of the disease or new a lesion develops, which does not correspond clinically or in trichoscopy to lichen planopilaris. %K lichen planopilaris %K squamous cell carcinoma %K cicatricial alopecia %K Liquen Plano %~
