Geographic Tongue and Fissured Tongue in 348 Patients with Psoriasis: Correlation with Disease Severity

الملخص EN

Geographic tongue (GT) and fissured tongue (FT) are the more frequent oral lesions in patients with psoriasis.

The aims of this study were to compare the prevalence of GT/FT between psoriasis group (PG) and healthy controls (HC) and investigate the correlation between GT/FT and psoriasis severity using the PASI and age of psoriasis onset.

Three hundred and forty-eight PG and 348 HC were selected.

According to the age of psoriasis onset, the individuals were classified as having early psoriasis and late psoriasis.

The severity of vulgaris psoriasis was determined according to PASI.

A follow-up was conducted in patients with psoriasis vulgaris (PV) with GT to evaluate the progression of oral and cutaneous lesions.

The FT and GT were more frequent in PG than in HC.

The incidence of GT was higher in patients with early psoriasis and that of FT in late-psoriasis.

There is association between psoriasis intensity and GT; and a higher monthly decrease of PASI score in patients without GT.

The presence of GT and FT is higher in PG than in the HC.

GT is associated with disease severity and may be a marker of the psoriasis severity.
