Multiple oral radiopaque masses leading to Gardner's syndrome diagnosis.

Gardner's syndrome, an autosomal dominant syndrome, is linked to familial adenomatosis polyposis (FAP), which is known mainly as a colorectal disease. FAP also presents extracolonically as intestinal polyposis, multiple osteomas, cutaneous cysts, or fibromas. This article reports the case of a 66-year-old white woman who was referred to the Oral Medicine Clinic, School of Dentistry, Universidade Vale do Rio Verde, Brazil, for evaluation of multiple sclerotic, asymptomatic masses in the jaws that were observed in a routine periapical radiographic exam by a dentist.

CD44/CD24 immunophenotypes on clinicopathologic features of salivary glands malignant neoplasms.

Background: Salivary glands malignant neoplasms (SGMNs) account for 3-6% of head and neck cancers and 0.3% of all cancers. Tumor cells that express CD44 and CD24 exhibit a stem-cell-like behavior.

Prognostic impact of p53 and p63 immunoexpression in oral squamous cell carcinoma.

Background: The role of p53 and p63 proteins in the prognosis of oral squamous cell carcinoma (OSCC) is still debatable. Our aim here was to investigate the relationship between the immunoexpression of these proteins with some clinicopathologic parameters of prognostic significance in OSCC.

Methods: Formalin-fixed paraffin-embedded sections from 106 patients were used for study together with the following data: primary site, histologic differentiation, recurrences, metastasis, disease-free survival and overall survival (OS).
