1/4. Proliferative verrucous leukoplakia: a case report.Proliferative verrucous leukoplakia (PVL) is a particularly aggressive form of oral leukoplakia that is resistant to treatment and presents a high risk of recurrence and malignant transformation. This article describes the microscopic and clinical characteristics of one case of PVL, which initially presented as hyperkeratosis with mild dysplasia and posteriorly developed multifocal areas and verrucous carcinoma despite treatment.- - - - - - - - - - ranking = 1keywords = leukoplakia (Clic here for more details about this article) |
2/4. leukoplakia of the prepuce with epidermolytic hyperkeratosis: a case report.A leukoplakic lesion of the prepuce is described with the histologic and ultrastructural features of epidermolytic hyperkeratosis. The lesion represents most likely a variant of epidermolytic leukoplakia recently observed in the vermilion border of the lip.- - - - - - - - - - ranking = 0.16666666666667keywords = leukoplakia (Clic here for more details about this article) |
3/4. Verruciform xanthoma. Case report and literature review.Verruciform xanthoma is a relatively uncommon lesion. Half of the reported cases occurred in the gingiva or alveolar ridge. In most cases, the clinical impressions are papilloma or verrucous carcinoma, which demonstrates the importance of the clinical and pathological recognition of this lesion. The cause of pathogenesis is still unknown since the first report in 1971. There are some cases reported in conjunction with leukoplakia, carcinoma in situ, pemphigus, and discoid lupus erythematosus (DLE), which merits close evaluation of this disease. This article reports two cases of verruciform xanthoma and reviews the evidence of its pathogenesis from the available literature.- - - - - - - - - - ranking = 0.16666666666667keywords = leukoplakia (Clic here for more details about this article) |
4/4. Case report: gastric carcinoma as a complication of dyskeratosis congenita in an adolescent boy.dyskeratosis congenita (DC), or the Zinsser-Engman-Cole syndrome, is a rare X-linked heritable disorder, affecting primarily the ectodermal tissues, with hyperpigmentation of the skin, leukoplakia of the buccal and anal mucosa, and nail dystrophy (1, 2). Aplastic anemia (3) and a variety of neoplasms (4, 5) are some of the extraectodermal manifestation of this disorder, which although X-linked recessive, has also been described in a few females (6, 7). Mental retardation, diarrhea, and gastrointestinal bleeding have been considered to be less frequent features (8). We report an adolescent Indian male who presented with all the ectodermal manifestations, as well as mental retardation, bone marrow aplasia, and gastrointestinal hemorrhage secondary to adenocarcinoma of the stomach.- - - - - - - - - - ranking = 0.16666666666667keywords = leukoplakia (Clic here for more details about this article) |
