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.

Whereas the common blue nevus usually has an innocuous clinical course, the cellular blue nevus may behave more aggressively and exhibit a greater rate of recurrence.30 Rare reports of malignant transformation have also been associated with the cellular cutaneous variant. Vermillion border of the lips is the most common site to find melanotic macules.[25]. The tongue also shows fissuring (deep grooves on the top and sides of the tongue), which often coexists with geographic tongue.

One of the most common causes of this ailment is hyper-pigmentation or oral Gurvits GE, Tan A. Melanin is the pigment derivative of tyrosine and is synthesized by melanocytes, which typically reside in the basal cell layer of the epithelium.4 Investigations into normal melanocyte homeostasis led to the discovery that keratinocytes control melanocytic growth.5 Yet the mechanisms by which melanocytes are stimulated to undergo cell division remain poorly understood. Studies have demonstrated 5year survival rates of 1540%. If this is the case, your doctor may prescribe an antifungal medication or retinoid.

Healthy oral soft tissue presents a typical pink to red hue that reflects the degree of keratinization, quantity and activity of melanocytes, vascularization, and type of submucosal tissue of distinct topographic areas. For cases of iatrogenic Kaposi sarcoma any immunosuppressive medication should be stopped or reduced if able. Black spots may vary based on what is causing them to appear. This technique has been successfully used for the evaluation of selected oral pigmented lesions.7 The second, reflectance confocal microscopy (RCM), allows the in vivo microscopic visualization of the skin and mucosa, which provides highresolution horizontal views with an approximate depth of 200300 m.8 This procedure can assist in the diagnosis and management of benign and malignant pigmented lesions of the lips.9 Because prospective and controlled studies detailing the predictive value and efficacy of dermoscopy and RCM for the diagnosis of oral pigmented lesions have not been performed, the practitioner should be wary of their use in common clinical dental practice. These macules often vary in shades of brown, size and are confluent, Although any oral site can be affected, in almost all cases pigmented macules appear on the buccal mucosae, lips and around the mouth.

The prognosis of melanoma can be ascertained by Breslows tumor thickness criteria, or Clarks level of invasion. Nevus cells initially maintain their residency at the basal layer, as cellular clusters at the junction of the epithelium and the underlying connective tissue (Figure 59). Minimum temperature needed for cell damage is cell specific, and melanocytes are very sensitive to low temperatures at 4C to 7C where cell death can occur. One of the main clinical and microscopic challenges in diagnosing oral melanoma is determining whether the lesion is a primary neoplasm or a metastasis from a distant site. brownblack pigment, and pheomelanin, a pigment of redyellow color.
