1/5. Proliferative verrucous leukoplakia: an aggressive form of oral leukoplakia.Proliferative verrucous leukoplakia (PVL) is an aggressive form of oral leukoplakia that is persistent, often multifocal, and refractory to treatment with a high risk of recurrence and malignant transformation. This article describes the clinical aspects and histologic features of a case that demonstrated the typical behavior pattern in a long-standing, persistent lesion of PVL of the mandibular gingiva and that ultimately developed into squamous cell carcinoma. prognosis is poor for this seemingly harmless-appearing white lesion of the oral mucosa.- - - - - - - - - - ranking = 1keywords = leukoplakia (Clic here for more details about this article) |
2/5. Oral squamous cell carcinoma around dental implants.It is well documented that oral squamous cell carcinoma (OSCC) is related to risk factors such as smoking and alcohol consumption as well as premalignant lesions and conditions such as leukoplakia, oral lichen planus (OLP), and previous malignancy of the upper respiratory system and gastrointestinal tract. Osseointegrated dental implants are rarely reported in association with OSCC. This article presents 2 cases of OSCC adjacent to dental implants in patients at risk for oral cancer--1 was a heavy smoker with OLP; the other had a history of previous oral and colon cancer. Six additional cases of malignancy adjacent to dental implants were retrieved from the literature; the majority of cases had at least 1 recognized risk factor for oral cancer. Although such cases are rarely reported, patients at risk for oral cancer, especially those with multiple existing risk factors, that present with failing dental implants should be thoroughly evaluated to rule out the presence of malignancy disguised as peri-implant disease.- - - - - - - - - - ranking = 0.1keywords = leukoplakia (Clic here for more details about this article) |
3/5. Intraoral leukoplakia, abrasion, periodontal breakdown, and tooth loss in a snuff dipper.dentists should be aware that snuff dipping or chewing is increasing in southern states and perhaps in other sections of the united states. These habits can lead to clinical leukoplakia, gingival recession, tooth abrasion, and periodontal bone destruction. The possibility also exists that a malignant transformation of leukoplakia can develop in persons who use snuff and other forms of tobacco.- - - - - - - - - - ranking = 0.6keywords = leukoplakia (Clic here for more details about this article) |
4/5. Acquired dyskeratotic leukoplakia.A 36-year-old woman developed progressive dyskeratotic leukoplakia of the palate, lips, attached gingiva, and labial surfaces of the genitalia. On microscopic examination, clusters of dyskeratotic cells were found throughout the epithelium, except in the basal cell layer. The clinical and histologic differential diagnosis included candidiasis, oral hairy leukoplakia, lichen planus, condyloma acuminatum, Darier's disease, hereditary benign intraepithelial dyskeratosis, and white sponge nevus. Her clinical and histologic findings do not permit classification into any of these well-recognized entities.- - - - - - - - - - ranking = 0.6keywords = leukoplakia (Clic here for more details about this article) |
5/5. Transformation of oral lichen planus to squamous cell carcinoma: a literature review and report of case.We have presented a case of malignant transformation of oral lichen planus along with a review of the literature and a brief description of the disease. We have attempted to indicate that within defined terms, oral lichen planus should be considered a pre-malignant lesion in which incidence of transformation approaches that of clinical oral leukoplakia, yet is clearly distinctive from that disease with regard to age and sex distribution. The erosive form of oral lichen planus most often precedes carcinomatous change. A protocol is described for documentation and periodic follow-up procedures for such patients to possibly intercept a developing malignancy.- - - - - - - - - - ranking = 0.1keywords = leukoplakia (Clic here for more details about this article) |
