Oral granulomatous diseases are frequently observed due to a wide variety of infections. These represent a unique form of the chronic inflammatory response. Granulomatous diseases of the oral tissues are uncommon and are difficult to diagnose due to various etiological agents. Over the years, emergence of accurate molecular diagnostic techniques has enabled identification of causative organisms of oral granulomatous diseases which were previously unknown. Oral granulomatous diseases are a large group of lesions which share similar histogenesis of granuloma formation. Therefore an extensive clinical, microscopic and laboratory evaluation is required to identify the source of the oral granulomatous diseases. This article highlights the etiology and histopathological features of granulomatous diseases of the oral cavity.
