Psoriasis of the tongue.
BACKGROUND
Psoriasis is a common, chronic dermatologic disease. Cases affecting the oral mucous membranes are rarely reported in the international literature, in particular tongue lesions are hardly ever documented.


METHODS
This article presents a 61 year old patient with persistent whitish lesion on his tongue. Biopsy specimens from mid surface and tip of the tongue were taken. Histopathologic sections were stained with haematoxylin-eosin (H-E) as well as with Periodic acid-Schiff (PAS) and examined by light microscopy.


RESULTS
Tongue lesions showing epithelial hyperplasia, parakeratosis, long papillae, neutrophils and microabscesses of Munro.


CONCLUSIONS
The reported case suggests that the clinical and histological appearances of the lesions are consistent with mucosal psoriasis.
