Assessment of cases of lichenoid granulomatous stomatitis in respect to demographics, histological features, and subcategories in known population

Introduction: Lichenoid granulomatous dermatitis (LGD) is widely encountered lesions with both oral as well as dermal manifestation. Present study was done to evaluate lichenoid granulomatous stomatitis cases. Materials and methods: 226 biopsies were exposed to special stains such as acid-fast bacilli (AFB), immunohistochemical staining for CD 68 and Grocott methenamine-silver (GMS), and periodic acid‐Schiff (PAS) stains. Results: Out of 226 patients, males were 84 and females were 142. Maximum cases were seen in age group 40–60 years (122) followed by >60 years (56) and 20–40 years (48). The common site was buccal mucosa seen in 128 (56.6%) cases followed by vestibule in 30 (13.2%), gingiva in 26 (11.5%), tongue in 20 (8.8%), lip in 12 (5.3%) and palate in 10 (4.4%). The common lesion was oral lichen planus seen in 142 (62.8%), carcinoma in situ in 12 (5.3%), squamous cell carcinoma in 8 (3.53%), pemphigus vulgaris in 10 (4.42%), leukoplakia in 24 (10.6%) and pemphigoid in 30 (13.2%) cases. Most lesions were of type I seen in 117 (51.7%) cases. Conclusion: Lichenoid granulomatous dermatitis poses variety of clinical as well as oral features. A long standing follows up and consideration of differential diagnosis is mandatory for better management of patients.
