Abstract Background and Aim: Orofacial granulomatosis (OFG) comprises a group of diseas- es characterized by non-caseating granulomatous inflammation affecting the soft tis- sues of the oral and maxillofacial region. Wiesenfeld introduced the term orofacial granulomatosis in 1985 for the first time. The precise cause of OFG is unknown; however, some theories have been suggested in- cluding allergy, infection and genetic predisposition. The clinical presentation can be highly variable, making the diagnosis difficult to es- tablish. The aim of this review was to define clinical features, differential diagnosis and treat- ment protocols of OFG. Materials and Methods: All English articles from 1950 to 2010 in Pubmed, InterS- cience, ScienceDirect, Google Scholar databases were searched using the keywords: orofacial granulomatosis, approach, and treatment. Persian articles were also selected from Iran Medex. Results and Conclusion: Because of the relatively nonspecific clinical findings asso- ciated with a variety of granulomatous diseases, the diagnosis of orofacial granulomat- ous often presents a dilemma for the clinician. The most common differential diagno- Corresponding author: sis includes Crohn's disease, sarcoidosis, and infection.
