An unusual case of oral sarcoidosis: A diagnostic dilemma.

Sarcoidosis is a rare type of multi-organ granulomatous disease. It is characterised by non-caseating necrotising granulomatous inflammation. The exact mechanism causing the disease is unknown due to its variation of manifestation in patients. The clinical presentation of this disease is protean, and often, patients remain asymptomatic throughout life. The most commonly affected organ by sarcoidosis is the lung accounting for up to 90% of all cases. Oral manifestation is a relatively rare presentation of sarcoidosis, and there are only a few cases reported till date. In this case report, the authors present a case of oral sarcoidosis of the retromolar trigone region.
