RESUMEN
Metastases from malignant tumors in the oral cavity are rare and comprise approximately 1% of all oral neoplasms, being more frequent in the jaws than in the soft tissues. The presentation of a gingival metastasis as the first manifestation of a primary tumor in the oral cavity is extremely rare. The objective of this review is to update the diagnosis and management of oral metastasis being the first clinical manifestation of the tumor and review all the cases published to date, providing a new original clinical case with very specific histopathological characteristics. We systematically reviewed the literature in order to find all the cases of primary lung tumors that appeared with a gingival metastasis as the first manifestation. The search process involved a total of 1916 articles. After reading the latter, 15 (one of them with two different cases) met the inclusion criteria. Of the 15 articles, 6 were rated as medium quality (40%) and 9 as high quality (60%). We present a lung adenocarcinoma that first manifested as a metastasis in the gum, simulating a benign lesion. The unusually high growth rate of this lesion should conduct to have other diagnostic possibilities, and histopathological confirmation is essential.
RESUMEN
BACKGROUND: Diagnosis of maxillary sinus pathology must include the clinical radiological study (CRS) and histopathological analysis. The aim of this study is 1) to describe the clinicopathological features of maxillary sinus lesions, obtained successively in a single medical centre over the last 10 years and 2) to determine the sensitivity and specificity for the diagnosis of malignant lesions based exclusively on the CRS. METHODS: It is a single-centre observational retrospective clinical study on patients who attended the University Hospital Complex of Santiago de Compostela (CHUS) with sinus pathologies during the period of 2009-2019. RESULTS: The sample consisted of 133 men (62.1%) and 81 women (37.9%), with an average age of 46.9 years (SD = 18.8). In terms of frequency, the most frequent pathology was the unspecified sinusitis (44.4%), followed by polyps (18.2%), malignant tumours (9.8%), inverting papilloma (7.5%), fungal sinusitis (4.7%), cysts (3.7%), benign tumours (2.3%), mucocele (2.3%) and other lesions (1.9%). Cysts and benign tumours were diagnosed earliest Vs malignant tumours (65.2 years (SD = 16.1)) were diagnosed the latest (p < 0.001). Based only on the CRS for malignancies, diagnostic indexes were 71.4% sensitivity and 97.9% specificity, with a Kappa value of 0.68 with (p < 0.001). CONCLUSION: Maxillary sinus pathology is very varied with therapeutic and prognostic repercussions. CRS is sometimes insufficient and histopathological confirmation is essential.

BACKGROUND: Minor salivary gland tumors (MSGTs) are infrequent, representing 10% to 15% of all salivary neoplasms. Despite this low frequency, a significant increase in the incidence of these tumors has been reported in the lasts 30 years. While tumors of the salivary glands can appear at any age, different authors consider the peak of incidence to be associated with old age (60+). The etiopathogenesis of MSGTs remains unclear. In this context, the aim of this study was to explore the hypothesis that age-related changes in salivary antioxidant capacity are involved in the pathogenesis of minor salivary glands tumors to identify possible preventive measures.Furthermore the study aimed to describe the clinico-pathological features of a multi-institutional case series of MSGTs which results are consistent with data in the literature. METHODS: An electronic search of the English language literature was performed using PubMed and Google scholar (

INTRODUCTION: Patients diagnosed with head and neck tumors, are treated by surgery, radiation therapy (RT), chemotherapy (CT) or a combination thereof. The goal is to describe the management protocol for patients subjected to radiation therapy (RT) and to study their long-term oral health status. MATERIALS AND METHODS: A retrospective study was performed in a sample of 50 patients. We analyzed the oral health status and all the variables included applying the adapted protocol of pre-RT. RESULTS: Prior to RT, 84% of patients required scaling and 32% conservative treatment. Around 74% of patients required at least one exodontia. The mean of exodontias for patients presenting Grade 3 of oral hygiene was 6.50 per person (p<0.0001). The pre-RT study of possible candida infection showed that 78% of patients were negative for this infection. The mean resting saliva production was 39.10 (SD: 23.30; range: 13-145), with a stimulated value of 64.78 (SD: 33.92; range: 16-200). CONCLUSIONS: All patients should be protocoled to ensure that they present optimal oral conditions prior to initiating RT treatment.
