The pyogenic granuloma is a relatively is an exaggerated tissue response to localised irritation or trauma.Histologically, pyogenic granuloma does not present as granuloma and is devoid of pus. It is filled with vascularchannels filled with inflammatory fluid, connective tissue with immature fibroblasts and inflammatory cellsscattered.It occurs most commonly in the gingiva and also lips, tongue and buccal mucosa are the othercommon sites. Melasma is a common skin condition hyperpigmentation of sun-exposed areas, especially onthe face which is usually light to dark brown, symmetrical and irregular in appearance.

The present case reports a localized inflammatory hyperplasia of the maxillary gingivalof a 38 year male patient who was suffering from melasma. Melasma is a disorder of hyperpigmentationwith psychological impacts affecting majorly the face. Excisional biopsy of the lesion revealed findingssuggestive of Pyogenic Granuloma. Excision of pyogenic granuloma may also predispose to recession ofinterdental soft tissue.
