title: Extensive intraoral blue nevus--case report.
abstract: Nevus is a congenital pigmented malformation rarely found in the oral mucosa. Around one third of cases located in this anatomical region are of the blue type, a histological variant with considerable tendency to malignancy. This study reports the case of a male patient, chronic smoker, with a blue nevus measuring 5 cm in diameter on the hard palate. Since controversy exists in the literature regarding the incisional biopsy of pigmented lesions with malignant or malignant potential, excision without previous biopsy of the lesion was the therapy of choice for this case. The patient was followed-up for two years with no sign of recurrence or malignant transformation.
