BACKGROUND: Lichen planopilaris (LPP) is a rare variant of cutaneous lichen planus that preferentially involves hair follicles. OBSERVATION: We describe the case of an 87-year-old woman with cicatricial alopecia due to lichen planopilaris. The diagnosis was based on clinical evaluation, histopathology and trichoscopy. Squamous cell carcinoma developed within the hairless area after 18 years of evolution. CONCLUSION: It 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.
