Exclusively oral psoriasis
Keywords:
psoriasis, oral cavity, mucosa.Abstract
Introduction: Psoriasis is a chronic inflammatory and recurrent skin disease that rarely occurs solely and primarily in the oral mucosa.
Objective: Describe a case of primary psoriasis of the oral mucosa.
Case presentation: A 16-year-old female patient attends consultation and reports "a spot that hurts when eating." Clinical observation revealed the presence of leukoplastic, exophytic plaque and an ulcer. Histopathological examination confirmed the suspicion of psoriasiform mucositis. The treatment chosen for the psoriatic lesions was topical application of betamethasone valerate 1 mg/g for three weeks. After two weeks of treatment, the patient returned for clinical reassessment and the treatment applied was found to have been successful.
Conclusions: Exclusively oral psoriasis is an uncommon condition. Multi-faceted clinical presentation and the absence of local or systemic associated alterations were key elements in the diagnostic suspicion. Surgical removal of the exophytic lesion and application of topical betamethasone led to locoregional control.
