The findings of this study highlight the higher prevalence of oral SCC among women and the increasing number of cases among young patients. Thus there is no specific risk group for oral SCC, as in the past. This fact needs to be taken into consideration in clinical routine care, so that apparently innocuous malignant lesions do not go unnoticed in these individuals.

The aim of this study was to describe the clinicopathological features of 21 cases of intraoral pleomorphic adenoma (PA), with emphasis on histopathological findings. Between 2000 and 2016, all patients diagnosed as intraoral PA were retrieved and histopathological slides stained with hematoxylin and eosin reviewed to confirm the diagnosis. All tumors were classified histologically according to Seifert et al (1980). The clinical and histopathological variables were analyzed using the Fisher’s exact test, considering a significance level of 5% ( P < .05). Plasmacytoid (85.7%), spindle (38.1%), and epithelioid (9.5%) myoepithelial cells were observed. Oncocytic (47.6%) and mucous (19%) cells were also found. The stroma was predominantly fibrous (95.2%), followed by myxoid (66.7%), hyaline (61.9%), and chondromyxoid (33.3%). Squamous (57.1%), adipose (47.6%), sebaceous (14.3%), and bone (14.3%) differentiations were found. Additionally, a group of tumors presented pleomorphism (23.8%), mitoses (14.3%), capsule infiltration (9.5%), and necrosis. The presence of cystic structures occurred significantly in patients older than 30 years ( P = .04) and mitoses were more observed in PA from buccal mucosa ( P = .026). All cases that presented plasmacytoid cells were smaller than 1.5 cm ( P = .015). All tumors with up to 50% stroma area presented with size smaller than 2.0 cm ( P = .013). Intraoral PA presents a large morphological spectrum and several microscopic features are associated with clinical findings.

Objective The aim of this study was to evaluate the knowledge and attitudes of dentists working in Primary Health Care Units from a Brazilian city, regarding oral cancer. Materials and methods A prospective, cross-sectional, epidemiologic survey was performed. Seventy-one dentists from Primary Health Care Units were contacted at their workplace, and participated of the study. Data were collected through a self-administered questionnaire of 31 multiple-choice questions addressing the main clinical features and risk factors for oral cancer. The questionnaire was divided into two sections: questions related to general data and self-perception of the participants regarding personal knowledge of oral cancer, and objective questions related to general information on oral cancer (clinical features, characteristics, traits, and risk factors). The data were tabulated and analyzed by descriptive statistics. Results Participants were mostly females (81.5%), less than 40 years of age (57.7%), who underwent training 10–20 years ago (47.9%). Most respondents (66.2%) considered their level of knowledge about oral cancer to be satisfactory. However, only 26.8% of tem felt that they were able to carry out diagnostic procedures for oral cancer. Most of them (95.8%) were interested in participating in training courses on Oral Diagnostics; 56.3% of them reported not having received any training or guidance on how to conduct an examination to detect oral cancer during undergraduate training. Conclusions These findings are consistent with previous reports and point to the need for new public policies to enable early diagnosis of oral cancer and a review of training in Oral Diagnostics in dental schools.
