Abstract
OBJECTIVE This study used array comparative genomic hybridization to assess copy number alterations (CNAs) involving miRNA genes in pleomorphic adenoma (PA), recurrent pleomorphic adenoma (RPA), residual PA, and carcinoma ex pleomorphic adenoma (CXPA). MATERIALS AND METHODS We analyzed 13 PA, 4 RPA, 29 CXPA, and 14 residual PA using Nexus Copy Number Discovery software. The miRNAs genes affected by CNAs were evaluated based on their expression patterns and subjected to pathway enrichment analysis. RESULTS Across the groups, we found 216 CNAs affecting 2261 miRNA genes, with 117 in PA, 59 in RPA, 846 in residual PA, and 2555 in CXPA. The chromosome 8 showed higher involvement in altered miRNAs in PAs and CXPA patients. Six miRNA genes were shared among all groups. Additionally, miR-21, miR-455-3p, miR-140, miR-320a, miR-383, miR-598, and miR-486 were prominent CNAs found and is implicated in carcinogenesis of several malignant tumors. These miRNAs regulate critical signaling pathways such as aerobic glycolysis, fatty acid biosynthesis, and cancer-related pathways. CONCLUSION This study was the first to explore CNAs in miRNA-encoding genes in the PA-CXPA sequence. The findings suggest the involvement of numerous miRNA genes in CXPA development and progression by regulating oncogenic signaling pathways.

Abstract
The Eph/ephrin system regulates many developmental processes and adult tissue homeostasis. In colorectal cancer (CRC), it is involved in different processes including tumorigenesis, tumor angiogenesis, metastasis development, and cancer stem cell regeneration. However, conflicting data regarding Eph receptors in CRC, especially in its putative role as an oncogene or a suppressor gene, make the precise role of Eph-ephrin interaction confusing in CRC development. In this review, we provide an overview of the literature and highlight evidence that collaborates with these ambiguous roles of the Eph/ephrin system in CRC, as well as the molecular findings that represent promising therapeutic targets.

Abstract
BACKGROUND Salivary gland carcinomas (SGCs) are a rare group of malignant neoplasms of the head and neck region. MicroRNAs (miRNAs) are a class of small non-coding RNAs that have been associated with the control biological process and oncogenic mechanism by the regulation of gene expression at the post-transcriptional level. Recent evidence has suggested that miRNA expression may play a role in the tumorigenesis and carcinogenesis process in SGCs. METHODS This review provides a comprehensive literature review of the role of miRNAs expression in SGCs focusing on the diagnostic, prognostic, and therapeutic applications. RESULTS In this review, numerous dysregulated miRNAs have demonstrated an oncogenic and suppressor role in SGCs. CONCLUSION In the future, these miRNAs may eventually constitute useful diagnostic and prognostic biomarkers that may lead to a better understanding of SGCs oncogenesis. Additionally, the development of therapeutic agents based on miRNAs may be a promising target in SGC treatment.

Abstract
Colony-stimulating factors (CSFs) are key cytokines responsible for the production, maturation, and mobilization of the granulocytic and macrophage lineages from the bone marrow, which have been gaining attention for playing pro- and/or anti-tumorigenic roles in cancer. Head and neck cancers (HNCs) represent a group of heterogeneous neoplasms with high morbidity and mortality worldwide. Treatment for HNCs is still limited even with the advancements in cancer immunotherapy. Novel treatments for patients with recurrent and metastatic HNCs are urgently needed. This article provides an in-depth review of the role of hematopoietic cytokines such as granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF), macrophage colony-stimulating factor (M-CSF), and interleukin-3 (IL-3; also known as multi-CSF) in the HNCs tumor microenvironment. We have reviewed current results from clinical trials using CSFs as adjuvant therapy to treat HNCs patients, and also clinical findings reported to date on the therapeutic application of CSFs toxicities arising from chemoradiotherapy.

Abstract
Merkel cell carcinoma (MCC) is an aggressive and rare cutaneous neuroendocrine carcinoma that predominantly affects the sun-damaged skin of the head and neck region, extremities, and trunk of older white individuals. Microscopically, MCC is characterized by nests or sheets of uniform small round blue cells with scant cytoplasm, granular nuclei with a salt-and-pepper chromatin pattern, high proliferative activity, and occasional necrosis. They are usually positive for epithelial and neuroendocrine markers, particularly for cytokeratin 20 and AE1/AE3 in a paranuclear dot-like staining. We herein contribute by reporting a case of MCC affecting the auricular pavilion of a 66-year-old female patient from Campinas, Brazil. Additionally, a review of the current literature is also included to analyze all the cases that have been reported in the English-language literature, totalizing 27 cases of MCC on the external ear. The 5-year overall survival rate for individuals with localized MCC is 50% and the most common treatment choice is the combination of surgery with adjuvant radiotherapy and sentinel lymph node biopsy.

Abstract
INTRODUCTION Neuroendocrine carcinoma is a rare form of cancer originating from neuroendocrine cells, with the lungs being the most common site of occurrence. These tumors have the potential to metastasize to the head and neck region. CASE REPORT A 57-year-old man, with a smoking history of 74 pack-years, presented with complaints of hoarseness, dry cough, dysphagia, and significant weight loss over a two-month period. During oral examination, a submucosal nodule in the left palatine tonsil was discovered. Histological analysis confirmed a poorly differentiated tumor consisting of large cells with nuclear pleomorphism and abundant cytoplasm. The tumor tested positive for CD56, chromogranin, synaptophysin, and EMA. Further imaging revealed a substantial endobronchial lesion in the upper segment of the left lower lobe. Biopsy results from this lesion were morphologically and immunohistochemically consistent with those from the oral lesion. A diagnosis of metastatic large-cell neuroendocrine carcinoma originating from the lung and involving the oral mucosa was established. CONCLUSION This case highlights the metastatic potential of pulmonary neuroendocrine carcinoma and its occurrence in atypical dissemination sites. Additionally, our findings underscore the importance of early detection of oral metastases to ensure accurate diagnosis and expedite appropriate treatment.

Abstract
A 54-year-old male patient complained of nasal obstruction and epistaxis for 2 years, with worsening of the symptoms in the preceding year. Physical examination revealed a friable, irregular mass, with yellowish secretion, in the left nasal fossa. Magnetic resonance imaging revealed an expansive lesion in the left nasal cavity, extending into the nasopharynx, ethmoid, right nasal cavity, and cortical bone of the hard palate. An incisional biopsy was then performed. Morphologically, a cellular malignant proliferation with a solid basaloid appearance admixed with adenoid cystic-like areas was observed. Immunohistochemistry revealed positivity for AE1/AE3, CK7, p63, and calponin, with focal labeling for CD117 and α-SMA. p16 had diffuse cytoplasmic and nuclear positivity. Ki-67 index was >80%. Given the morphological and immunohistochemical aspects, the diagnosis was conclusive for HPV-related multiphenotypic sinonasal carcinoma. The tumor was considered irresectable, and the patient was submitted to induction chemotherapy with docetaxel, cisplatin, and infusional 5-fluorouracil, with significant regression after therapy, followed by chemoradiotherapy with carboplatin, without limiting toxicities. The patient is currently under regular follow-up, with complete clinical and radiological response. To date, there are no reports in the literature of induction chemotherapy use or its complete therapeutic responsiveness related to this lesion. A brief literature review was included with the main epidemiological, clinical, therapeutic, and prognostic aspects regarding the 85 cases reported in the literature, including ours.

Abstract
We present a 21-day-old female child presenting with a large oral epithelialized tumor implanted at the rhinopharynx and ethmoid plate through a cleft palate, associated with feeding and respiratory difficulties. The histopathological exam showed mature central adipose tissue, hair follicles, sebaceous glands, and neurovascular structures, lined by keratinized stratified squamous epithelium. Proliferative cartilaginous, glandular, lymphatic, bony, and immature myxoid tissue was seen at the posterior region and insertion. Despite the characterization of the tumor as a teratoma containing structures derived from the three embryonic leaflets, the anterior portion presented a microscopic bigeminal pattern fully compatible with hairy polyp.

Abstract
In this systematic review, we aimed to evaluate the clinicopathological profile of sclerosing polycystic adenoma (SPA). PubMed, Scopus, EMBASE, Lilacs, Web of Science, and gray literature were searched to access cases of SPA in salivary glands. One hundred and thirty cases of SPA were found across 61 selected articles. SPA affected mainly the parotid gland of adults with a mean age of 44.6 years old, with a slight preference for females. The lesion was usually presented as a painless firm mass with a long period of evolution. Histologically, they are well-delimitated lesions composed of acinar and ductal elements with a variety of cytomorphologic features surrounded by a densely collagenized stroma. PI3K was the most common gene mutation related to SPA. SPA is a benign condition that mainly affects the parotid gland of female patients and it is usually treated by surgical resection with a good prognosis.

Abstract
PURPOSE It has been hypothesised that secretory carcinoma of the salivary gland (SCsg) might have a lactational-like differentiation. Therefore, we aimed to assess the immunoexpression of breast hormonal receptors and milk-related proteins in cases of SCsg and other salivary gland tumours with prominent secretory activity. METHODS Immunohistochemistry against prolactin and growth hormone receptors, lactoferrin, human milk fat globule 1, MUC 1 and MUC4 was performed in twelve cases of SCsg and 47 other salivary gland tumours. RESULTS Most cases of SCsg were negative for prolactin and growth hormone receptors. All cases of SCsg showed enhanced membranous-cytoplasmic staining for human milk fat globule 1, a pattern seen in other tumour groups. Only SCsg showed widespread strong staining for lactoferrin, concomitantly in the cell compartment and secretion. The other positive tumour types exhibited restricted staining. MUC1 and MUC4 showed no distinct pattern of expression. CONCLUSION Although SCsg failed to demonstrate a complete lactational-like differentiation, lactoferrin showed a distinctive expression pattern in SCsg compared to other tumour types, which makes it a good marker to help in its differential diagnosis.

Abstract
OBJECTIVE To analyze the proteomic profile of salivary pleomorphic adenoma (PA) and carcinoma ex pleomorphic adenoma (CXPA) samples and correlate them with the malignant transformation of the PA. MATERIALS AND METHODS Thirty samples (10 PA, 16 CXPA, and 4 residual PA) were microdissected and submitted to liquid chromatography-tandem mass spectrometry (LC-MS/MS). The proteomic data and protein identification were analyzed through LC-MS/MS spectra using the MaxQuant software. RESULTS The proteomic analysis identified and quantified a total of 240 proteins in which 135 were found in PA, residual PA, and CXPA. The shared proteins were divided into six subgroups, and the proteins that showed statistically significant differences (p > 0.05) and fold-change > or <2.5 in one subgroup to another subgroup were included. Seven proteins (Apolipoprotein A-I-APOA1, haptoglobin-HP, protein of the synaptonemal complex 1-SYCP1, anion transport protein of band 3-SLC4A1, subunit μ1 of AP-1 complex-AP1M1, beta subunit of hemoglobin-HBB, and dermcidin-DCD) were classified as potential protein signatures, being HP, AP1M1, and HBB with higher abundance for PA to residual PA, APOA1 with higher abundance for PA to CXPA, SLC4A1 with lower abundance in the PA to CXPA, SYCP1with lower abundance for residual PA to CXPA, and DCD with higher abundance in the CXPA with epithelial differentiation to myoepithelial differentiation. CONCLUSIONS In this work, we demonstrated the comparative proteomic profiling of PA, residual PA, and CXPA, and seven were proposed as protein signatures, some of which may be associated with the malignant phenotype acquisition.

Abstract
OBJECTIVES In this systematic review, we aimed to evaluate the clinicopathological and prognosis data of patients with salivary gland myoepithelial carcinoma. MATERIALS AND METHODS MEDLINE/PubMed, Scopus, and Embase search was performed with the keywords "myoepithelial carcinoma" "malignant myoepithelioma," and "salivary glands." Primary salivary glands myoepithelial carcinoma that fulfilled the World Health Organization diagnostic criteria were included. The Joanna Briggs Institute tool was used to assess the risk of bias. RESULTS Forty-three studies (71 patients) met the inclusion criteria. The patients showed a mean age of 56.4 ± 19.6 years with no sex predilection. The parotid was the most affected gland (49.3%). The tumor presented as an asymptomatic (65.1%) mass (84%). The most common histological findings were the presence of clear tumor cells (39.7%) and multinodular growth patterns (60.7%). Multivariate analysis showed plasmacytoid cell type (p = 0.010) and solid growth pattern (p = 0.003) were related to decreased disease-free survival. Surgery alone was the most used treatment (53.5%). Patients with a combination of treatments showed a longer disease-free survival (p = 0.049). The 2-year and 5-year overall survival rates were 67.5% and 46.1%, respectively. CONCLUSION Salivary gland myoepithelial carcinoma showed no sex predilection, with a higher incidence in the parotid gland. Cell type, growth pattern, and treatment type may be related to a lower disease-free survival. Overall, salivary gland myoepithelial carcinoma presented low recurrence and metastasis rates. Registration and protocol: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 checklist and registered in the International Prospective Register of Systematic Reviews (PROSPERO) database (CRD42022311512).

Abstract
Pleomorphic adenoma (PA) is the most common salivary gland tumor, accounting for 50%-60% of these neoplasms. If untreated, 6.2% of PA may undergo malignant transformation to carcinoma ex-pleomorphic adenoma (CXPA). CXPA is a rare and aggressive malignant tumor, whose prevalence represents approximately 3%-6% of all salivary gland tumors. Although the pathogenesis of the PA-CXPA transition remains unclear, CXPA development requires the participation of cellular components and the tumor microenvironment for its progression. The extracellular matrix (ECM) comprises a heterogeneous and versatile network of macromolecules synthesized and secreted by embryonic cells. In the PA-CXPA sequence, ECM is formed by a variety of components including collagen, elastin, fibronectin, laminins, glycosaminoglycans, proteoglycans, and other glycoproteins, mainly secreted by epithelial cells, myoepithelial cells, cancer-associated fibroblasts, immune cells, and endothelial cells. Like in other tumors including breast cancer, ECM changes play an important role in the PA-CXPA sequence. This review summarizes what is currently known about the role of ECM during CXPA development.

Abstract
INTRODUCTION Spindle cell carcinoma (SpCC) or sarcomatoid carcinoma, is a rare variant of squamous cell carcinoma (SCC) that has a variable proportion of carcinomatous and sarcomatous components. Here, we reported an immunohistochemical study of a spindle cell carcinoma with a challenging morphological diagnosis. CASE REPORT A 50-year-old woman with a previous history of nodular melanoma was referred for evaluation of a painful papule in the lower lip. After surgical resection, neoplastic cells showed focal positivity for CK-14, αSMA, p63, and confirmed the strong positivity for S100 and vimentin. Tumor cells were negative for HMB-45, Melan A, SOX-10, AE1/AE3, 34βE12, CK5-6, CAM5.2, EMA, desmin, calponin, CD10, CD34, and CD68. With these findings, a diagnosis of SpCC was rendered. The patient presented lung and dorsal metastases after 12 months and after 3 years of follow-up, the patient died. CONCLUSION In summary, a careful correlation of microscopy and immunohistochemical characteristics is required for the proper diagnosis of this lesion.

Abstract
PURPOSE To evaluate metabolic alterations along with the carcinoma ex pleomorphic adneoma (CXPA) development of lacrimal glands (LG). METHODS Four samples of the normal LG (NLG), 9 of pleomorphic adenoma (PA), 4 of residual PA (rPA), and 4 of CXPA of LG were included. GLUT-1, HIF-1α, FASN, and adipophilin by immunohistochemical stains were performed in the selected cases. RESULTS Was observed higher expression of markers associated with glycolytic and lipid metabolism in the tumor tissue samples when compared to the NLG samples. Additionally, GLUT-1, FASN, and Adipophilin were more expressed in CXPA samples while HIF-1α in PA samples. CONCLUSIONS In conclusion, our results demonstrate overexpression of FASN and Adipophilin in CXPA which may reflect a metabolic shift toward lipogenesis in cancer cells.

Abstract
Zika virus (ZIKV) has the ability to cross placental and brain barriers, causing congenital malformations in neonates and neurological disorders in adults. However, the pathogenic mechanisms of ZIKV-induced neurological complications in adults and congenital malformations are still not fully understood. Gas6 is a soluble TAM receptor ligand able to promote flavivirus internalization and downregulation of immune responses. Here we demonstrate that there is a correlation between ZIKV neurological complications with higher Gas6 levels and the downregulation of genes associated with anti-viral response, as type I IFN due to Socs1 upregulation. Also, Gas6 gamma-carboxylation is essential for ZIKV invasion and replication in monocytes, the main source of this protein, which was inhibited by warfarin. Conversely, Gas6 facilitates ZIKV replication in adult immunocompetent mice and enabled susceptibility to transplacental infection. Our data indicate that ZIKV promotes the upregulation of its ligand Gas6, which contributes to viral infectivity and drives the development of severe adverse outcomes during ZIKV infection.

Abstract
Male patient 60-year-old was referred from another service for expert review of a lesion in the submental region. Pathological review revealed morphological features compatible with salivary gland Secretory carcinoma (SC) in cervical lymph node. The patient underwent removal of the left submandibular gland, left neck dissection and biopsy of left labial commissure region. Anatomopathological examination was observed tumor cells arranged in a solid and ductal/cystic pattern, with abundant droplets of secreted eosinophilic material within these structures and extensive hyalinized area, which presented few cells arranged in a ductal pattern. It was possible to observe the presence of extracapsular extension of neoplastic cells > 6 mm, base on this aspects, Carcinoma ex pleomorphic adenoma was suspected. Immunohistochemical panel showed positivity for mammaglobin, s100, CK7, and adipophilin and negativity for myoepithelial markers and PAS in SC cells. The myoepithelial markers showed positivity for residual cellsin hyalinized area, corresponding to residual Pleomorphic adenoma (PA). In view of these findings, the diagnosis of Secretory carcinoma ex pleomorphic adenoma (SCXPA) was established.

Abstract
INTRODUCTION Placental villitis is characterized by the presence of inflammatory infiltrate in the placental villous. The objective of this study was to characterize in villitis of unknown etiology (VUE) of the human placentas the subpopulation of M1, important effector cells, and M2 macrophages, immunoregulatory cells. METHODS Sixteen cases of VUE and three control placentas were examined using immunohistochemistry with antibodies for CD3, CD68, CD11c, and CD163. RESULTS CD11c appeared predominantly in the inflamed villi when compared to the normal areas (p<.001). These cells corresponded to 41.2% of the macrophage population in the inflamed area and were mainly present inside the villi (36%). With regards to CD163, these cells tended to be in higher amounts in the inflamed villi when compared to CD11c and normal areas. DISCUSSION We conclude that the almost exclusive presence of M1 macrophages in the inflamed areas suggests the influence of these cells in the pathogenesis VUE. The greater amount of M2 in villitis and normal areas suggests a possible immunoregulatory mechanism of the inflammatory process in VUE.

Abstract
The myoepithelial cell seems to play an important role as a tumor suppressor in the development of carcinoma ex pleomorphic adenoma. Nevertheless, interesting aspects concerning the other side of the coin, i.e., the contribution of the myoepithelial cell to cell proliferation, were brought to light. Here we highlighted the studies in which myoepithelial cells were presented as tumor suppressors and promoters in the context of PA malignant transformation. In conclusion, even if in a paracrine way, divergent signals can alter the suppressor role of the myoepithelial cell and induce it to compose a microenvironment propitious to the tumor progression of the malignant cells. This would cause myoepithelial cells to succumb and malignant epithelial cells to initiate progression beyond the basal membrane.

Abstract
The detection of Zika virus (ZIKV) in immunoprivileged anatomical sites, potential sites for viral persistence, may guide the confirmation of undefined cases of ZIKV infection and also bring to light unknown pathways of viral transmission. Thus, this study aimed to characterize ZIKV infection in stratified, standardized placental samples in women with exanthematic febrile manifestations during pregnancy and compare findings to the standard investigation protocol of official health agencies. To this end, a case series of placental findings within a prospective cohort study was conducted over a period of 24 months. Serum/urine were obtained at the time of clinical case identification. Placental sampling was performed following standard investigation protocol (samples of 1.0 cm sent to a reference laboratory) and in a systematic way at various regions, such as chorionic plate, chorionic villi, basal plate, amniotic membrane, and umbilical cord, for subsequent ZIKV identification and quantification. Clinical information was obtained and histological preparation with hematoxylin–eosin staining for morphological evaluation was performed. This case series included 17 placentas systematically collected. Of these, 14 were positive by qRT-PCR for ZIKV, 5 in the umbilical cord, 7 in the amniotic membrane, 7 in the chorionic plate, 13 in the chorionic villi, and 7 in the basal plate, whereas none were reported by the reference laboratory. The most common morphological and anatomopathological findings were increased stromal cellularity, villitis, calcification, maternal vascular malperfusion, placental hypoplasia, and maternal–fetal hemorrhage (intervillous thrombi). Seven women presented positive testing for ZIKV in serological and/or molecular tests during gestation in urine. While viral quantification in urine ranged from 101 to 103 FFU eq/ml, that in different placental regions ranged from 103 to 108 FFU eq/g. Thus, ZIKV can infect different regions of the placenta and umbilical cord of pregnant women, showing that the systematic collection and adequate storage of the placenta is fundamental for the detection of ZIKV in this organ. The detection of ZIKV in the placenta after several months of initial symptoms suggests that this tissue may be a site for viral persistence during pregnancy.

Abstract
AIMS The hallmarks of type 2 diabetes (T2D) are hyperglycaemia and insulin resistance. These factors, at the cellular level, are associated with mitochondrial dysfunction and increased glucose uptake. Such events are poorly explored in the context of the salivary glands. In this study, we present a series of eight cases of a distinct salivary gland lesion characterised by multiple oncocytic cysts, and we provide new pathological insights regarding its pathogenesis. METHODS AND RESULTS Seven patients (87.5%) had confirmed T2D, and obesity was identified in five (62.5%) patients. Clinically, the patients showed bilateral parotid gland swelling with recurrent episodes of pain and enlargement. Imaging examination revealed multiple cystic lesions in both parotid glands. Microscopically, the parotid glands showed multiple cysts of different sizes, lined by oncocytic epithelial cells. Intraluminally, strongly eosinophilic glass-like crystalloid material was observed. Immunohistochemical studies were performed, and the most notable finding was glucose transporter 1 (GLUT1) overexpression in the oncocytic cysts which is not observed in any other oncocytic lesion of patients without T2D. In addition, high expressions of mitochondrial antigen, fission 1 protein and mitofusin-2 were observed in the oncocytic epithelium of the cysts. Furthermore, most of the oncocytic cysts showed a pattern of cytokeratin expression consistent with striated ducts. CONCLUSIONS These results strongly suggest that T2D is associated with alterations in GLUT1 expression in the cells of striated ducts with mitochondrial dysfunction, causing a hyperplastic process characterised by multiple oncocytic cysts. For this lesion, the designation of 'diabetes-associated-bilateral multiple oncocytic cysts of the parotid gland' is proposed.

Abstract
OBJECTIVE As the genetic changes in recurrent pleomorphic adenoma (RPA) have not yet been investigated, the aim of this study was to assess the genomic profile of somatic copy number alteration in RPA and pleomorphic adenoma (PA) by using array comparative genomic hybridization (aCGH). STUDY DESIGN Four cases of RPA and 13 cases of PA were evaluated by using aCGH, using a 180 K platform. Data were analyzed by using Nexus Copy Number Discovery. RESULTS The RPA group rarely showed any copy number alteration, except for 1 case that exhibited losses in 5 p15.33 p15.1, 5 q13.1 q35.3 and 12 q12 q13.11. The PA group also showed few copy number alterations, and the most frequent findings involved chromosomes 8: 8p21.3-p12 (gain), 8q12.1 (loss), 8p23.3-q24.3 (gain), and 8q12.1-q21.11 (gain). Genomic amplifications were revealed in the PA group, and the relevant affected genes were MAML2 and LIFR. CONCLUSIONS PA and RPA exhibit few somatic copy number alterations and show a similar genomic profile on aCGH.

Abstract
The purpose of the present study is to report 2 cases of odontogenic carcinoma with dentinoid, a rare low-grade odontogenic carcinoma associated with facial deformity and bone loss, and to investigate the presence of pathogenic mutations in these samples. By using a next-generation sequencing approach, we sequenced a panel of 50 oncogenes and tumor suppressor genes commonly mutated in human cancer. Microscopic features of both cases revealed solid areas of malignant odontogenic tumor with a large amount of dentinoid material. We identified pathogenic mutations in the genes CTNNB1 and APC, both of which are part of the Wnt-signaling pathway. Consistent with Wnt-signaling activation, both tumors showed strong β-catenin accumulation in the cytoplasm and in the nuclei. The molecular profile of odontogenic carcinoma with dentinoid may help in its diagnosis, as well as in the identification of potential molecular targets for therapy in the future.

Abstract
Pleomorphic adenoma (PA) is the most common salivary gland neoplasm and, although
mostly benign, recurrences, being called recurrent pleomorphic adenoma (RPA) and
malignant transformation to carcinoma ex pleomorphic adenoma (CXPA), do occur.
Recently, attention has been focused on molecular targeted cancer therapy in
various tumors, including salivary gland tumors. The aim of this study was to
investigate the role of estrogen receptor (ER), progesterone receptor (PR), and
human epidermal growth factor receptor-2 (HER-2) in PA, RPA, and CXPA. In total,
20 cases of PA, 18 of RPA, and 7 cases of CXPA were immunohistochemically
studied for ER, PR, and HER-2. For evaluation of ER and PR, only nuclear
expression and greater than 10% positive cells were regarded as cutoff criteria.
HER-2 was evaluated semiquantitatively and graded from 0 to 3+. HER-2
amplification was assessed by chromogenic in situ hybridization (CISH). Tumors
were negative for ER, PR, and HER-2 in all cases of PA and RPA. A case of CXPA
showed moderate and complete membranous staining, and 6 cases were negative.
HER-2 amplification was not observed in any case. In conclusion, the lack of ER,
PR, and HER-2 expression in PA, RPA, and CXPA suggests that these proteins are
not involved in progression, recurrence, or malignant transformation of PA.

Abstract
The objective of this study is to report a case of carcinoma ex pleomorphic adenoma subclassified as secretory carcinoma ex pleomorphic adenoma frankly invasive. A 60-year-old male patient attended our service for cervical injury assessment, painless with slow and progressive growth for about 3 years. At the clinical examination, an increase in volume in the submandibular region and a lesion in the region of the nasolabial sulcus were observed. A biopsy of the lesion was performed and the morphological characteristics were compatible with secretory carcinoma of the salivary gland. The patient underwent a radical cervical emptying, excision of the left submandibular gland, and removal of the lesion in the left nasogastric sulcus. At the macroscopic examination, the submandibular gland presented a hardened, heterogeneous nodule, poorly delimited, with gross calcification at the center, measuring 2.0 × 1.5 × 1.5 cm. At the histopathological examination, eosinophilic cells containing intracytoplasmic vacuoles, with a ductal formation and solid arrangement and dystrophic calcification, were observed corresponding to the old hyalinized areas of residual PA. In view of these findings, the diagnosis was secretory carcinoma ex adenoma pleomorphic frankly invasive of the submandibular gland with extension to the nasogenian sulcus. Complementary immunohistochemical examination was carried out evidencing positivity for mammaglobin, S100, and CK7 in tumor cells and negativity for calponin, 1A4, and p63.
Conclusion: Although CXPA is a rare lesion and is more common in parotid glands, it may affect other locations. Several histopathological phenotypes may arise from the malignant transformation of the PA, but to the best of our understanding, this is the first case of secretory carcinoma ex pleomorphic adenoma reported in the literature.

Abstract
Abstract
Introduction
Villitis is characterized by the presence of inflammatory infiltrate (CD8 lymphocyte) in the placental villous and is classified as to the etiology in known and unknown. In most cases, villitis is idiopathic (villitis of unknown etiology [VUE]) because no microorganisms are evident and there are no maternal symptoms or signs. It has recently been proposed that pregnancy is, in fact, an active and highly regulated immune process in which macrophages play an important role. Macrophages may present with M1 phenotype, important effector cells, or M2 phenotype, capable of suppressing the function of M1 macrophages and influencing immunoregulation and tissue repair. CD68 antibody recognizes macrophages M1 and M2, whereas CD11c and CD163 antibodies are specific for the identification only of M1 and M2 macrophages, respectively. The objective of our study is to characterize in human placentas in the subpopulation of M1 and M2 macrophages in VUE.
Methods
Sixteen cases of chronic villitis (all without an identifiable etiologic agent) and three control placentas were examined using immunohistochemistry with antibodies for CD68, CD11c, CD163, and CD3.
Results
CD68 and CD163 were present in all cases in the normal areas. CD68, CD163, and CD11c were present in the villous stroma and in the intervillous space in the inflamed areas. The percentage of CD68-positive macrophages was higher than CD163- and CD11c-positive macrophages in all specimens studied. A total increase of CD68, CD163, and CD11c with the predominance of CD11c over CD163 in the inflamed areas was observed.
Conclusion
The predominance of M1 macrophages (CD11c) in the inflamed areas suggests the influence of these cells in the pathogenesis VUE. The higher amount of M2 (CD163) in the inflamed villous compared to normal areas suggests a possible immunoregulatory mechanism of the inflammatory process in VUE.

Abstract
Abstract
Introduction
Pleomorphic adenoma (PA) is a benign lesion of the salivary glands that can suffer malignant transformation to carcinoma ex adenoma pleomorphic (CXPA). The pathogenesis of CXPA has been attributed to the accumulation of genetic disorders in preexisting PAs. However, there is no confirmation whether there is a common target gene involved in all histopathological subtypes or the decisive factors for malignant transformation in a histopathological subtype are specific.
Objectives
To further analyze genes found in PA and CXPA using the CGH-array technique. The genes found were analyzed using the InteractiVenn virtual tool (http://www.interactivenn.net/) and grouped into a Microsoft Excel worksheet.
Results: Of the 460 genes amplified in the studied samples, 287 (62.4%) were related only to CXPA, whereas 144 (31.3%) were related to residual PA. Twenty-nine (6.3%) of these genes were common between residual PA and CXPA. Regarding the degree of invasion of CXPA, there was an increase in the number of genes amplified as the degree of invasion and aggression increased: 8 genes related to intracapsular CXPA, 65 to minimally invasive CXPA, and 373 to weakly invasive. Moreover, when comparing residual AP and intracapsular CXPA, two genes were common to these groups: ERRB2 and GRB7. As for the histological subtype, the high-grade samples had more amplifications (320 amplified genes) than the low-grade ones (129 genes). Three of these genes were common among residual PAs and CXPA: HMGA2, RPSAP52, and LOC100129940. As for the replicates, MYNC, ERBB2, BRIP1, and HMGA2 were the most repeated amplified genes in the residual PAs. HMGA2, ERRBB2, CDK12, RPSAP52, LOC100129940, and LOC100507250 were the genes with the most replicates in CXPA.
Conclusion
HMGA2, ERRB2, and RPSAP52 may play a key role in PA carcinogenesis, whereas GRB7, CDK12, MYNC, and BRIP1 appear to act as coadjutants.

Abstract
OBJECTIVE The aim of this study was to determine the proteome of adenoid cystic carcinoma (AdCC) and polymorphous adenocarcinoma (PAc) and to identify a protein signature useful in distinguishing these two neoplasms. STUDY DESIGN Ten cases of AdCC and 10 cases of PAc were microdissected for enrichment of neoplastic tissue. The samples were submitted to liquid chromatography-tandem mass spectrometry (LC-MS/MS), and the proteomics data were analyzed by using the MaxQuant software. LC-MS/MS spectra were searched against the Human UniProt database, and statistical analyses were performed with Perseus software. Bioinformatic analyses were performed by using discovery-based proteomic data on both tumors. RESULTS LC-MS/MS analysis identified 1957 proteins. The tumors shared 1590 proteins, and 261 were exclusively identified in AdCC and 106 in PAc. Clustering analysis of the statistically significant proteins clearly separated AdCC from PAc. Protein expression 10 times higher in one group than in the other led to a signature of 16 proteins-6 upregulated in AdCC and 10 in PAc. A new clustering analysis showed reverse regulation and also differentiated both tumors. CONCLUSIONS Global proteomics may be useful in discriminating these two malignant salivary neoplasms that frequently show clinical and microscopic overlaps, but additional validation studies are still necessary to determine the diagnostic potential of the protein signature obtained.

Abstract
Dentinoid has been mentioned as a frequent component in several types of benign odontogenic tumors; however, there are some other very rare dentinoid-producing odontogenic tumors that have been described, which are not recognized in the current World Health Organization Histological Classification of Odontogenic Tumours. In this context, we report an unusual malignant odontogenic tumor containing dentinoid located in the left maxilla of a 41-year-old man. The lesion was initially diagnosed and treated as a cemento-ossifying fibroma. After 7 years, a tumor was noted at the same location and was diagnosed as pleomorphic adenoma. The patient developed a new lesion 2 years later. Histological features included an epithelial proliferation of basaloid and clear cells, some with peripheral palisading, which were scattered both in a fibrous stroma and within an amorphous eosinophilic dentinoid product. Because of doubts about the first 2 diagnoses and the current situation, all histopathological slides were reviewed in our service as a consultation case, and the findings were consistent with the diagnosis of an odontogenic carcinoma with dentinoid. Immunohistochemical analysis was performed and an ultrastructural study by scanning electronic microscopy and energy-dispersive X-ray microanalysis was made to characterize dentinoid material. After 1 year of follow-up, the patient is alive and free of the disease. This case highlights the wide variability regarding cytological evidence of malignancy, and adds a new case of odontogenic carcinoma with dentinoid, which represents a distinct entity with locally aggressive behavior and should be considered be included in a future World Health Organization Histological Classification of Tumours.
