Hyperpigmentation of Skin (Melasma) with Solitary Oral Pyogenic Granuloma Lesion: A Case Report

Abstract

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 vascular
channels filled with inflammatory fluid, connective tissue with immature fibroblasts and inflammatory cells
scattered.It occurs most commonly in the gingiva and also lips, tongue and buccal mucosa are the other
common sites. Melasma is a common skin condition hyperpigmentation of sun-exposed areas, especially on
the face which is usually light to dark brown, symmetrical and irregular in appearance. Although melasma
can affect all races and both sexes, it is more commonly seen in women of child-bearing age and in darkskinned
individuals living in areas with intense ultraviolet (UV) radiation. Hyper pigmentation on exposed
areas such as the face can be a source of cosmetic concern for patients, that can negatively impact quality
of life (QOL). The present case reports a localized inflammatory hyperplasia of the maxillary gingival
of a 38 year male patient who was suffering from melasma. Melasma is a disorder of hyperpigmentation
with psychological impacts affecting majorly the face. Excisional biopsy of the lesion revealed findings
suggestive of Pyogenic Granuloma. Excision of pyogenic granuloma may also predispose to recession of
interdental soft tissue.
