Abstract
Linear lichen planus pigmentosus is considered as a combined type of linear lichen planus and lichen planus pigmentosus (LPP), and only 4 such cases have been reported in the dermatologic literature. We report one case of linear LPP that developed on the patient's mandibular area and the right side of the extremities. The lesions on the face presented as a dark-brown streak, which was parallel to the lower lip line. The pathological findings confirmed the diagnosis of LPP. To the best of our knowledge, this pattern of LPP has not been described before. While we are uncertain as to the cause of this patterning, we believe that it will contribute to research on the pathogenesis of LPP.
Keywords: Linear lichen planus pigmentosus, facial dermatosis, extremities.
