Objectives: Chronic ulcerative stomatitis (CUS) is a chronic, ulcerative condition of the oral cavity, clinically and histologically similar to oral lichen planus (OLP), first described as a new disease entity in 1990 by Parodi et al. In this review, 30 years after our first description of CUS, we aimed to systematically review the literature of CUS cases reported ever since. Methods: We present a systematic review of CUS literature cases, performed in compliance with the PRISMA statement. Results: Of 125 retrieved articles, 20 satisfied inclusion criteria. These described 76 CUS cases, all presenting orally evident disease: erosions (55%), white lesions (49%), erythema (49%), ulcerations (34%) were the most frequent signs; 54% experienced discomfort/pain. Topographically, buccal mucosa (68%) and gingiva (54%) were the most affected locations, followed by tongue (42%), hard palate (27%), labial mucosa (22%), and widespread involvement (15%). Great diagnostic delay (6.3 years) was evidenced highlighting CUS is an entity too often misdiagnosed. Histopathology found lichenoid features (46%) and non-specific inflammation (54%). Extra-oral involvement was reported in 21%, especially as LP (69%). Of DIF, 97% were positive; 3% negative, compensated by positive IIF, permitting diagnosis. Of patients on steroids, only 12% reported therapeutic success; most steroid-non-responsive patients passed to antimalarials, with 91.66% success when used alone, 100% success in combination therapy. Conclusion: Dermatologists should suspect CUS in chronic steroid-unresponsive erosive/ulcerative stomatitis. In these cases, to diagnose CUS, the presence of stratified epithelium–specific antinuclear antibodies (SES-ANA) should be investigated through immunofluorescence. Once diagnosed, CUS can be treated with antimalarials, which are an effective treatment contrarily to corticosteroids.
