Abstract :

Melanomas are malignants neoplasms arising from melanocytes, originating from the neural crest cells, it account for 1-3% of all malignants tumors and the incidence is increasing in Western Countries up to 6-7% yearly. Most of the intraoral melanomas had radial growth phases similar to Acral Lentiginous Melanoma (ALM) of the skin. The most common site for mucosal melanoma is the head and neck region (55%), followed by the anal/rectal region (24%), female genital tract (18%) and urinary tract (3%). Oral melanomas comprise 50% of head and neck melanomas and the most frequent site of intraoral melanoma is the palate, followed by maxillary gingiva. In a previous study, mandibular gingival melanomas comprised 7% of 703 cases. Sortino-Rachou et al. reported a total of 124.436 oral cancer and 319 cases of primary oral melanoma from 67 cancer registries in five continents from 1998 to 2002, the result showed that OMM accounts for 0.26% of all oral cavity cancers. A 37 years old woman reported to the Comprehensive Dental Center in Acarigua-Venezuela referred by a general dentist who saw an unusual type of lesion in the lingual mandibular gingiva of 2 months of evolution with an insidious onset and growing in size, it was asymptomatic, non-ulcerated. She was on healthy condition, on examination a nodular single 2Ã?Â?1.5 cm black-brown mass smooth surface indurated with sessile base and surrounded the interproximal distal space between tooth 15 and 16 and end with small 5 mm mass on the buccal interproximal gingiva. The pigmentation was only seen on the lingual area. A re-motion of the first lower molar was demanded for a good sample. The lesion was positive for melanoma level III according with Prassad et al. The patient received oncologic treatment.
