Oral Postinflammatory Pigmentation: Clinicopathologic Features of Nine Cases

Oral postinflammatory pigmentation (OPP) is a pigmentary change of the oral mucosa caused by high melanin production, often associated with chronic inflammatory disorders. Several conditions could lead to OPP, including oral lichen planus (OLP), oral lichenoid lesion (OLL), pemphigus, and pemphigoid. Here, we present 9 OPP cases. The main clinical characteristic in all the cases was oral black to brown pigmentation, localized or diffuse, microscopically exhibiting melanin deposition in the lamina propria.
