It is an endocrinal disorder where there is an increased amount of adrenocorticotropic hormone (ACTH) as a result of deficient amounts of hormones being produced from the adrenal cortex.

Cutaneous overproduction of melanin may be associated with a variety of mechanisms, but most commonly with increased sun exposure. In fact, there is still debate as to whether nevus cells are a distinct cell type derived from the neural crest or if they are simply a unique or immature form of melanocyte.4 Nonetheless, the lesional nevus cells are cytologically and biologically distinct from the melanocytes that colonize the basal cell layer of the epidermis and oral epithelium.

In rare cases, multifocal lesions have been described. Most common oral sites include the hard palate and gums.
