The dentist will typically: Examine the spot carefully under good light, noting its size, location, shape, colour and edges

Exact preoperative diagnosis is difficult to achieve and they might mimic pathologies of surrounding organs or structures because of their atypical presentation

Melanin pigmentation has been reported to be most intense at the tips of the rete ridges [31, 34]

This chromatic variability not only reflects the genetic factors that regulate melanin synthesis by melanocytes and its subsequent transfer to adjacent keratinocytes but is also influenced by external factors such as trauma, inflammation, hormonal fluctuations, exposure to certain pharmacological agents, external agents that can pigment the mucosa, and radiation, all of which can induce an increase in melanin production

However, virtually all patients acquire resistance to this therapy and experience disease relapse

These UV-independent melanogenesis studies have established MT-1 as the reference tool for dissecting MC1R-specific pigmentation biology from UV-dependent mechanisms
