title: Lichen planus pigmentosus of the oral mucosa: a rare clinical variety.
abstract: In this paper, we describe a case of lichen planus of the mouth with intense melanosis, in a middle-aged white male. Due to its unusual clinical characteristics, we believe that this case represents a rare variant of lichen planus of the oral mucosa. The histopathologic findings, differential diagnosis and its possible connection with lichen planus pigmentosus of the skin are discussed.
