1/7. Blue nevus of the hard palate.The occurrence of a blue nevus of the hard palate in a 72-year-old man is reported. Of the 25 previously documented cases of blue nevus of the oral cavity, 19 were on the hard palate, three on the upper lip, and one each on the lower lip, buccal mucosa, and soft palate. Fourteen were in women and 11 were in men. All but five patients were younger than 50 years of age. The size of the asymptomatic, flat to somewhat elevated, blue-black lesion varied up to 5 mm except for one that was 10 mm in the greatest dimension. Most nevi were of unknown duration and were found incidentally during dental examination. The histogenesis of extracutaneous blue nevus is undetermined but derivation from melanogenic potential of Schwann or endoneurial cells or from stimulation of retained melanoblasts in the stroma developing into melanocytes and formation of blue nevus is possible.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
2/7. Multiple focal pigmented lesions in the maxillary tuberosity and hard palate: a unique display of intraoral junctional nevi.The pigmented conditions located in the oral cavity have a diverse genesis ranging from vascular lesions to exogenous and endogenous pigmentations. In this report we have documented the unusual occurrence of multiple intraoral junctional nevi in a patient. A review of the patient's past dental records revealed that 2 of these lesions were first noticed 8 years earlier; however, no efforts were made to identify the nature of the pigmentations. Removal of 4 lesions and subsequent histopathological analysis revealed the presence of junctional nevi. This case illustrates the importance of a thorough clinical and histological work-up when dealing with pigmented lesions in the oral cavity. The excision of all suspected oral nevi is warranted because they cannot be clinically differentiated from other pigmented lesions, including oral melanoma. In addition, the potential of junctional nevi to undergo malignant transformation in the oral cavity is undetermined.- - - - - - - - - - ranking = 3keywords = oral cavity, cavity (Clic here for more details about this article) |
3/7. Pigmented lesions of the oral cavity: review, differential diagnosis, and case presentations.Pigmented lesions are commonly found in the mouth. Such lesions represent a variety of clinical entities, ranging from physiologic changes to manifestations of systemic illnesses and malignant neoplasms. Evaluation of a patient presenting with a pigmented lesion should include a full medical and dental history, extraoral and intraoral examinations and, in some cases, biopsy and laboratory investigations. In this paper, an algorithm is proposed for the assessment of pigmented lesions of the oral cavity, and 3 patients with such lesions are described.- - - - - - - - - - ranking = 5keywords = oral cavity, cavity (Clic here for more details about this article) |
4/7. Spitz nevus of the palate. Report of a case.A 4-year-old Japanese girl with a nonpigmented nodule on the anterior portion of the palate since birth is described. The overall microscopic appearance of the lesion was very similar to that of Spitz nevus of the skin. diagnosis of Spitz nevus (mixed epithelioid cell and spindle cell nevus) was made on the basis of the clinical and histologic criteria for differentiating this lesion from malignant melanomas and common compound nevi. Positive immunostaining of epithelioid and spindle cells for S-100 protein and neuron-specific enolase was also indicative of their nevocellular nature. review of the cases of Spitz nevus from the literature revealed that the present case most probably represents the first reported instance of this type of nevus in the oral cavity.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
5/7. Pigmented lesions of the oral cavity.The factors that produce dark pigmentation of the oral soft tissues are described. Examples are given of aberrations of the melanin-forming cells in the oral cavity and a new case of oral blue nevus is added to the literature. A unique case of localized melanosis of the tongue is described clinically and histopathologically.- - - - - - - - - - ranking = 5keywords = oral cavity, cavity (Clic here for more details about this article) |
6/7. nevus sebaceus of Jadassohn: a rare oral presentation.nevus sebaceus of Jadassohn occurring exclusively in the oral cavity as a single lesion has not, to our knowledge, been reported previously. A case of this rare developmental anomaly at the palatine papilla of a 40-year-old woman is described.- - - - - - - - - - ranking = 1keywords = oral cavity, cavity (Clic here for more details about this article) |
7/7. melanoma and the differential diagnosis of oral pigmented lesions.There are many pathologic processes that occur in the mouth which have various intraoral manifestations. The differential diagnosis of pigmented lesions of the oral cavity takes on a high degree of significance because therapy may span such a wide range from no treatment at all to massive radical resection for melanoma. A thorough understanding of pigmented lesions of the oral cavity would assist the clinician in establishing a diagnosis and subsequent treatment plan. A comprehensive review of the literature and a discussion of oral pigmented lesions including infiltrative malignant melanoma is presented.- - - - - - - - - - ranking = 2keywords = oral cavity, cavity (Clic here for more details about this article) |
