Abstract
OBJECTIVE This study aimed to analyse the clinical and histopathological characteristics of focal oral melanocytic lesions in a Brazilian reference service in Oral and Maxillofacial Pathology. MATERIALS AND METHODS A cross-sectional study was conducted over an 18-year period. Demographic data and clinical features were collected from the archives, and all biopsy specimens diagnosed as oral melanocytic lesions were retrieved and reviewed. RESULTS We identified 339 melanocytic lesions. Of these, 191 were melanotic macules, 112 melanocytic nevi, 14 mucosal lentigo simplex, 12 melanomas, 9 solar lentigos, and 1 melanoacanthoma. Lesions occurred mostly in white-skinned (74.2%) women (65.2%). The main reported clinical aspect was the macule (67.4%), and the most affected site was the lip vermilion (25.4%), followed by the palate (22.9%). Melanomas were larger in size and were observed in older patients with an overall shorter time of onset. The most frequent subtypes of melanocytic nevi were intramucosal (44.6%), compound (24.1%), and blue nevus (20.5%). They showed a heterogeneous architectural pattern with the presence of the three cell types. CONCLUSION The most frequent lesions are melanotic macule and nevus, especially the intramucosal subtype. Patients are usually white-skinned women presenting a small, long-lasting, macular lesion on the lip vermilion or palate.

Abstract
AIMS Autoimmune polyglandular syndrome type I (APS-I) is a rare condition of autosomal recessive and monogenic inheritance, which is characterized clinically by at least two signs of the classic triad: mucocutaneous candidosis, hypoparathyroidism, and Addison's disease. This study aims to report the oral manifestations of APS-I in a 42-year-old woman, who attended the Special Care Dentistry Center. METHODS AND RESULTS The patient presented with hypoparathyroidism, diabetes mellitus, and autoimmune hepatitis. Chronic hyperplastic candidosis (CHC) was the main oral manifestation and it was diagnosed based on clinical and cytologic characteristics. Microstomia, angular cheilitis, xerostomia, enamel hypoplasia, and microdontia were also present. CONCLUSIONS CHC was treated with topical nystatin and oral fluconazole, resulting in a significant improvement of the lesions.

Abstract
BACKGROUND Actinic cheilitis is induced by chronic exposure to ultraviolet radiation and shows solar elastosis, a feature that has been associated with mast cell infiltrates. This study aimed to investigate the area of solar elastosis, collagen loss, and mast cell infiltrates in a series of actinic cheilitis. METHODS We evaluated the epithelial dysplasia in 52 cases of actinic cheilitis and the solar elastosis with Weigert's resorcin-fuchsin. Collagen loss was evaluated with Picrosirius red, analyzed under polarized microscopy, and scored from 1 to 3. Elastosis proportionate area (EPA) was calculated with image software. Mast cells were highlighted with toluidine blue stain. RESULTS EPA varied from 2% to 45%, with a mean of 17.1% in the cases, with no differences among epithelial dysplasia degrees. Most cases presented collagen loss scores of 2 or 3, and higher loss of type I collagen was associated with older age. Mast cell density was higher in severe epithelial dysplasia (P = 0.002) and in high-risk cases (P = 0.01). CONCLUSION Actinic cheilitis presented variable EPA and marked loss of type I collagen; however, these features were not associated with the degrees of epithelial dysplasia. Besides, mast cell density increased with epithelial dysplasia worsening and this was not associated with elastosis area or collagen loss.

Abstract
BACKGROUND Actinic cheilitis (AC) is a potentially malignant disorder of the lip, characterized by epithelial and connective tissue alterations caused by chronic exposure to ultraviolet radiation. In the past decades, diverse studies have been conducted in lip carcinogenesis and many biomarkers have been identified in lip lesions, yet there is no scientific evidence that determines its usefulness in the clinical setting or in histopathological routine. Therefore, we conducted the first systematic review in this field to summarize the results of published studies on immunohistochemical biomarkers in lip carcinogenesis, to evaluate if there is a marker than can distinguish the different histological grades of AC. MATERIAL AND METHODS Retrospective studies that investigated immunohistochemical biomarkers in AC defined on standardised histological assessment were gathered from five databases and evaluated. Each study was qualitatively evaluated using the Critical Appraisal Tools from SUMARI. RESULTS The proliferation marker Ki-67 was the most studied biomarker and we observed, through meta-analysis, that it was differently expressed between AC and lip cancer, but not in AC subgroups. Most articles had a high risk of bias. CONCLUSIONS In summary, the literature lacks quality follow up studies in actinic cheilitis. Multi-centre cohort studies, with patients stratified by treatment type and the use of image analysis software, could be the solution to further address the issues of investigating potentially malignant lesions and help change clinical practice, in terms of individualizing patients' treatment and prognosis prediction.

Abstract
Clear cell odontogenic carcinoma (CCOC) is a rare and aggressive malignant epithelial neoplasm, which occurs most frequently in the mandible of elderly patients. Morphologically, CCOC shares similar characteristics with other clear cell tumors, especially hyalinizing clear cell carcinoma of the salivary glands (HCCC). Both CCOC and HCCC are known to harbor EWSR1 rearrangements, especially the EWSR1-ATF1 gene fusion, which indicates a possible link between the two lesions. So far, this fusion has been demonstrated in five cases of CCOC in the literature. Herein, we add another CCOC case to the literature, which arose in the mandible of an 82-year-old female patient and was proven to harbor the EWSR1-ATF1 gene fusion. Immunohistochemically, this case was focally positive for CK7, CK14, CK19 and p63. The patient was referred to surgical treatment; however, she died of disease 2 months after the diagnosis, thereby demonstrating the aggressive nature of this tumor.

Abstract
Salivary duct carcinoma (SDC) is one of the most aggressive salivary gland tumors, and prognosis remains poor for most patients. The aim of this study was to investigate the prognostic implications of biomarker immunoprofile in a cohort of SDC and to identify molecular characteristics through next-generation sequencing (NGS) in a subset of cases. Clinicopathological and follow-up information of 25 cases diagnosed as SDC was collected. Immunoexpression of AR, HER-2/neu, GATA3, CK5/6, and MIB1 was analyzed, and ERBB2 (HER-2/Neu) gene amplification was investigated by fluorescence in situ hybridization. Cases were classified under the "SDC revised classification system." Eight SDC cases were analyzed by targeted NGS for detection of gene fusions and variants. Overall survival and disease-free survival were analyzed with Kaplan-Meier curves and Cox regression. Most cases expressed AR (100%), GATA3 (73%), and CK5/6 (76.5%), and 42% expressed HER-2/neu. ERBB2 gene amplification was proven by fluorescence in situ hybridization in 7 of 15 (46%) cases. Apocrine HER2 (AR+/HER2+) subtype was significantly associated with lower overall survival (P = .05). NGS analysis revealed 9 pathogenic mutations in 7 SDC cases, and the most frequently mutated gene was HRAS (4/9) followed by PIK3CA (2/9) and TP53 (2/9). One case (1/9) presented homozygous deletion of locus 9p21 (CDKN2A), and another case (1/9) showed MDM2 amplification. In conclusion, we demonstrated that Apocrine HER2 (AR+/HER2+) is a potential biomarker of poor outcome in SDC. Furthermore, NGS analysis revealed recurrent mutations in SDC.

Abstract
PURPOSE Salivary gland tumors are complex and have a great histomorphological diversity; more than 30 histological subtypes are currently described and the study of proteins that help understand and differentiate these tumors is essential. We aimed to analyze the immunoexpression of cyclooxygenase-2 (COX-2) and cyclin D1 proteins in pleomorphic adenomas (PA), mucoepidermoid carcinomas (MEC) and adenoid cystic carcinomas (AdCC) of salivary glands. METHODS A total of 38 PA, 12 AdCC and 12 MEC underwent immunohistochemical study by the polymeric biotin-free technique. Immunopositive cells were analyzed semi-quantitatively. For statistical analysis, a significance level was set at p ≤ 0.05. RESULTS Overall, these tumors were more prevalent in women (n = 37). The mean age of these patients was 58-year-old and the parotid gland was the most affected anatomic site (n = 33). All cases of AdCC and MEC showed immunopositivity to cyclin D1; however, 39.5% of the PAs were negative (p < 0.001). Regarding COX-2 immunoexpression, we observed that all cases of CME were positive, whereas 60.5% of the PA and 75% of the CAC analyzed were completely negative (p = 0.042). CONCLUSIONS The overexpression of COX-2, observed only in MEC, emphasizes that salivary gland tumors have different profiles. Cyclin D1 is more immunoexpressed in malignant tumors. Together, these immunohistochemical findings may be useful in differentiating the studied tumors.

Abstract
BACKGROUND We analyzed the different grades of dysplasia in the epithelium adjacent to lip squamous cell carcinoma (LSCC), as a parallel to actinic cheilitis (AC) that suffered malignant transformation. METHODS Forty samples of epithelium adjacent to LSCC were histologically graded according to the World Health Organization (WHO) and the binary systems. The expression of mutated p53 was evaluated through immunohistochemistry. RESULTS According to WHO system, 37.5% of the cases were graded as mild, 45% as moderate and 17.5% as severe dysplasia (P = 0.09). Considering the binary system, 90% of the cases were classified as low-risk and 10% as high-risk lesions. Mutated p53 was present in 73.3% of mild, 88.8% of moderate and 71.4% of severe dysplasia cases. Considering the binary system, 80.5% of the low-risk and 75% of high-risk lesions were immunopositive; 62.5% expressed the protein in both tumor cells and adjacent epithelium; 17.5% in adjacent epithelium only, and 7.5% in LSCC islands only (P = 0.03). CONCLUSIONS We observed heterogeneous grades of epithelial dysplasia in the epithelium adjacent to LSCC, which indicates that the analysis of AC morphological features is insufficient to predict patient's prognosis and to determine a treatment decision. Positive expression of mutant p53 in mild dysplasia reinforces this idea.

Abstract
Adenoid cystic carcinoma (AdCC) of the salivary glands is characterized by MYB-NFIB or MYBL1-NFIB fusion, prolonged but relentlessly progressive clinical course with frequent recurrences, and development of distant metastasis resulting in high long-term mortality. Currently, no effective therapy is available for patients with advanced non-resectable and/or metastatic disease. Complicating the clinical management of this patient group is the lack of prognostic markers. The purpose of this study is to investigate the prognostic value of 1p36 loss in patients with AdCC. The presence of 1p36 deletion and gene fusions involving the MYB, NFIB, and MYBL1 genes in a cohort of 93 salivary gland AdCCs was studied using fluorescence in situ hybridization. These results were statistically correlated with clinical data and outcome. Deletion of 1p36 in AdCC was identified in 13 of 85 analyzable cases (15.29%). MYB-NFIB fusion was detected in 57/85 (67.1%), MYBL1-NFIB fusion in 12/85 (14.1%), MYB-X fusion in 4/85 (4.7%), MYBL1-X in 4/85 (4.7%), and NFIB-X in 2/85 (2.4%) of AdCC cases. None of the 1p36-deleted samples showed MYBL1 rearrangement. Statistical analysis demonstrated a significant correlation between 1p36 deletion and advanced tumor stage and solid histology (p = 0.0061 and 0.0007, respectively). Kaplan-Meier survival curves showed statistically significant correlations between 1p36 deletion and decreased overall survival, disease-specific survival, recurrence-free interval, and recurrence-free survival, all of which were maintained in multivariate analysis. We demonstrate that 1p36 deletion can serve as an indicator of unfavorable outcome of patients with salivary gland AdCC.

Abstract
Background Ameloblastoma (AMB), odontogenic keratocyst (OKC) and adenomatoid odontogenic tumor (AOT) are epithelial odontogenic lesions with diverse biologic profiles. Defects in regulation of apoptosis and cell cycle may be involved in the development and progression of those lesions, therefore we aimed to investigate the expression of Bcl-2, Bax and p53 to better understand the possible role of these proteins in AMBs, OKCs and AOTs. Material and Methods The studied sample consisted of 20 AMBs, 20 OKCs and 20 AOTs. Immunohistochemistry technique was performed for the antibodies p53, Bcl-2 and Bax. Immunoreactivity was observed in the epithelial component and positive cells were counted in five fields (100x magnification). Statistical analysis was performed with Kruskal-Wallis and Spearman tests (p<0.05). Results All lesions exhibited staining for the three studied proteins. There was no statistically significant associations between the expression of proteins and the lesions, however we identified a positive correlation between the expression of p53 and Bcl-2 (r = 0.200) and a negative correlation between p53 and Bax expressions (r = -0.100). In addition, p53 and Bax were similarly expressed between AMBs and OKCs. Bcl-2 was similarly expressed in AMBs and AOTs. Conclusions Apoptosis regulatory proteins, as well as cell cycle proteins, are differently expressed in epithelial odontogenic lesions and their expression is possibly related to the biological behavior of AMB, OKC and AOT. Key words:Odontogenic tumors, apoptosis, apoptosis regulatory proteins, p53 tumor suppressor protein, immunohistochemistry.

Abstract
BACKGROUND DNA repair systems play a critical role in protecting the human genome from damage caused by carcinogens. Modifications in DNA repair genes may be responsible for tumor development and resistance of malignant cells to chemotherapeutic agents. The major pathway for oxidative DNA damage repair is the base excision repair pathway. This study aimed to assess the immunoexpression of DNA repair proteins APE-1 and XRCC-1 and its association with clinical, histologic, and survival parameters in oral tongue squamous cell carcinoma, to investigate a possible role for those proteins in tumor behavior. METHODS The expression of APE-1 and XRCC-1 was evaluated by immunohistochemistry in 82 cases of oral tongue squamous cell carcinoma. Histopathological grading was performed for each case. Pearson's chi-square and Fisher's exact tests were used to determine the association between protein expressions and clinicopathological features of tumors, whereas Kaplan-Meier curves and Cox regression were used to analyze disease-specific and disease-free survival. Statistical significance was set at P ≤ 0.05. RESULTS APE-1 was highly expressed in the nucleus and cytoplasm in 64.6% of cases, and XRCC-1 showed overexpression only in the nucleus in 61% of cases. High expression of XRCC-1 was significantly associated with tumors at early clinical stages (I and II, P < 0.01) and nodal status (P = 0.03). Both proteins were not associated with other clinical parameters, histopathological grading, or survival. CONCLUSIONS DNA base excision repair proteins APE-1 and XRCC-1 are upregulated in oral tongue squamous cell carcinoma, and XRCC-1 expression is associated with better clinical staging and nodal status.

Abstract
The angiotensin I-converting enzyme (ACE) activity was measured in urine, serum, and tissues from rats with carbon tetrachloride (CCl4)-induced acute renal failure on days 1, 2, 3, and 7 after CCl4 administration. Serum ACE increased on days 1 to 3. Heart, lung, small intestine, brain, and testis ACE decreased, whereas kidney and liver ACE remained unchanged. Urine ACE activity increased from day 1 to day 3. Our data suggest that the increase in serum ACE may be secondary to the ACE release from the damaged tissues, and that the urine ACE increase may be due to the kidney proximal tubule damage. This work supports the contention that an increase in urine ACE may be an indicator of damage to the proximal tubule.
