Prominent fungiform papillae in guttate psoriasis.

Three patients presented with widespread guttate psoriasis of explosive onset which involved the palms and soles (exanthematic guttate psoriasis) and followed, in each case, a haemolytic streptococcal throat infection. At the height of the effluorescence the lingual fungiform papillae were very numerous, red and prominent and their subsequent course paralleled that of the skin lesions. This oral finding has not been reported previously in patients with psoriasis.
