Gingival enlargement, pyogenic granuloma, lobular capillary hemangioma, oral exophytic lesion


Gingival enlargement is quite common, and occurs as a result of response to varied stimuli and or interactions with the host and the environment. This lesion represents a reactive hyperplasia. Pyogenic granuloma is one of the commonest exophytic lesions found in the oral cavity. Its histological variants are lobular capillary hemangioma (LCH) and non-lobular capillary hemangioma (non-LCH). This growth usually responds well to adequate plaque control, elimination of causative irritants and management of tissue. This case series highlights two cases of localized gingival enlargement, with histologic presentations and its management with emphasis on the importance on patient awareness and motivation.

Conclusion: Awareness of clinical presentations and histologic variants will aid clinicians in arriving at an appropriate diagnosis, as well as reduce the incidence of recurrence, thereby reducing the possibility of a misdiagnosis.

Recommendation: Clinicians should have a good knowledge of the common lesions that occur on the gingiva and be able to distinguish lesions by considering all possibilities before arriving at final diagnosis.
