Melanocytic nevi include a diverse group of clinically and/or microscopically distinct lesions.18 Unlike ephelides and melanotic macules, which result from an increase in melanin pigment synthesis, nevi arise as a consequence of melanocytic growth and proliferation.11 In the oral cavity, the intramucosal nevus is most frequently observed, followed by the common blue nevus.19 Compound nevi are less common, and the junctional nevus and combined nevus (a nevus composed of two different cell types) are infrequently identified.

There are four main clinicopathologic subtypes of cutaneous melanoma: superficial spreading melanoma, lentigo maligna melanoma, acral lentiginous melanoma, and nodular melanoma (Figures 510 and 511).33 In the first three subtypes, the initial growth is radial, where the melanocytic tumor cells spread laterally and therefore superficially.

Awareness of the epidemiologic and biologic properties of cutaneous melanoma is necessary for the clinical practitioner. The condition is associated with poor oral hygiene, smoking, Candida albicans infection, and some antibiotics (e.g., minocycline [Minocin], linezolid).4 The hyperpigmentation is due to bacteria trapped in the filiform papillae that produce porphyrins.

Owing to its rare occurrence, even the most renowned clinical cancer centers do not have a large enough cohort of oral melanoma cases to reliably and significantly correlate the histologic findings with prognosis.44 Thus, apart from tumor thickness greater than 5 mm and the presence of lymphovascular invasion, many of the histologic prognostic parameters of cutaneous melanoma (i.e., Breslows classification and Clarks level of invasion) do not apply to oral melanoma.3,6,47. Current time: 04/08/2023 11:24:36 p.m. UTC The condition is usually painless, and no treatment is needed.
