Giant cell lichenoid stomatitis - an oral medicine case book

Abstract

A 53-year-old female patient presented with a two-week history of intermittently painful oral mucosal lesions when eating spicy, salty or sour foods. The patient reported a long-term history of psoriasis treated by topical corticosteroids only. The remainder of the patient’s medical history was unremarkable. On intraoral examination, lesions were noted bilaterally in the posterior buccal commissures, appearing as centrally erosive lesions bound by white striations (Figure 1). Additionally, there were areas of desquamative gingivitis in the anterior maxillary gingiva. The clinical suspicion was that of oral lichen planus or oral lichenoid lesions. An incision biopsy from the left buccal mucosa was performed and submitted for histological assessment.
