Dermoscopy and Clinicohistopathological Profile of Lichen Planopilaris Restricted to the Face: A Case Series of Six Unusual Cases

This case series examined six unusual cases of lichen planopilaris (LPP) restricted to the face, a rare form of autoimmune cicatricial alopecia. The study included five men aged 32–60 years and a 12-year-old girl, marking the youngest known case. Patients exhibited hyperpigmented atrophic patches and scarring alopecia on the face, with the chin being the most affected area. Dermoscopy revealed reduced hair follicles, cicatricial alopecia, and various pigmentation patterns. Histopathology showed perifollicular inflammatory infiltrate and fibrosis. The study suggested that regular shaving and mustard oil application might trigger facial LPP. Treatments included hydroxychloroquine, corticosteroids, and steroids, with most patients showing a favorable response. The study emphasized the need for early diagnosis and treatment to prevent significant morbidity.
