ORAL MANIFESTATIONS OF PSORIASIS

Abstract

A 67-year-old male patient complained of pain and burning in the oral mucosa. On physical examination, erythematous plaques with whitish areas on the bilateral buccal mucosa and angular cheilitis were observed. Well-demarcated erythematous plaques covered by keratotic scales were also observed in the region of the ankle, trunk, and abdomen. Topical use of Nystatin and Miconazole was prescribed, but with no remission of the lesions and symptoms. Patient reported having Psoriasis and Psoriatic Arthritis. An incisional biopsy was performed in the labial commissure region and revealed hyperkeratosis and elongated epithelial projections in addition to areas of neutrophilic infiltration forming Munro´s abscesses. The final diagnosis of chronic interface mucositis compatible with psoriasis was performed. Topical use of clobetasol propionate gel 0.5 mg/g was prescribed, and laser therapy was performed (660 nm/100mw/40s), with partial regression of the lesions observed. Support: CAPES, CNPq.
