Background: Lichen planus (LP) is an inflammatory dermatosis with an unknown etiology. Although usually lichen planopilaris (LPP) occurs within terminal hair follicles; there are some reports of concomitant involvement of vellus hairs that present with papular eruption of the face along with frontal fibrosing alopecia (FFA). Method: Here we report three patients presented with asymptomatic facial papules with histologic examination in consistence with lichen planopilaris. Result: Based on these cases report isotretinoin can be an effective modality in managing this unusual variant of LPP/FFA. Conclusion: This study showed a significant response to oral retinoid in all cases. Limitation: We need large sample size to show isotretinoin is effective on treatment of this form of LPP. …show more content…
(5) The outstanding feature of this study is the significant response to oral retinoid in all cases. Material and methods: CASE 1: A 30-year-old woman presented with papular eruption on her face that had been started 1.5 years before her visit to our center.

Whereas the examination of other sites of her scalp was completely
