History

A diagnosis of postinflammatory hyperpigmentation should be considered if a history of a preceding pathologic process or injury to the affected area of hyperpigmentation is present.

Physical Examination

The distribution of the hypermelanotic lesions depends on the location of the original inflammatory dermatosis. The color of the lesions ranges from light brown to black, with a lighter brown appearance if the pigment is within the epidermis (ie, epidermal melanosis) and a darker gray to bluish appearance if lesions contain dermal melanin (ie, dermal melanosis). Note the image below.
