Introduction:
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.
Material And 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.
