Background:
The aim of this study was to examine the relationship of geographic tongue to psoriasis.
Methods:
We report a comparative study on two groups of patients: the first (20 patients) with cutaneous psoriasis and lesions of the oral mucosa similar to geographic tongue; the second (20 patients), with benign migratory glossitis only. Biopsy samples of the lingual mucosa were taken from both groups.
Results:
The histologic examination of oral biopsies from the first groups showed typical features of psoriasis. The second group showed the same features of psoriasis in 80% of patients.
Conclusions:
The clinical and histopathologic findings support the hypothesis that migrant glossitis can be considered an expression of oral psoriasis.
