RESUMO

OBJECTIVE: The aim of the present study was to carry out a systematic review of available data regarding case reports and case series of oral and maxillofacial benign fibrous histiocytoma (BFH). STUDY DESIGN: A search strategy was performed using the PubMed, Web of Science, Scopus, and EMBASE electronic databases. RESULTS: Male individuals (56.89%) were more affected, with a mean age of 34.55 ± 20 years. The buccal mucosa (20.33%) represented the most common site, with the clinical presentation of a painless (86.95%) nodule (98.03%). The clinical hypothesis of a fibroma was reported in most cases (31.57%). Radiographic presentation of intraosseous lesions showed multilocular radiolucent images (55.55%). Regarding the histopathologic features, the biphasic population of fibroblastic and histiocytic cells was seen in 21 cases (39.62%), and a spindle-shaped fibroblastic cell population organized into a storiform pattern was observed in 25 cases (47.16%). CD68 (n = 26) and vimentin (n = 25) showed immunoreactivity in all BFH cases in which they were used. All cases were treated with a surgical resection, and 8.10% recurred. CONCLUSIONS: The current systematic review demonstrated that BFH represents a rare lesion that mainly affects the buccal mucosa of male individuals, and the treatment is mainly surgical with a good prognosis.

RESUMO

To integrate the available data published on malignant peripheral nerve sheath tumours (MPNST) of the oral and maxillofacial region. Searches in Embase, PubMed, Web of Science and Scopus were conducted for the identification of case reports/case series in English language. The risk of bias was assessed using the Joanna Briggs Institute tool. Outcomes were evaluated by Cox regression and Kaplan-Meier methods. A total of 306 articles were retrieved, 50 of which reporting 57 MPNST were included. The lesion showed a predilection for the mandible (n = 18/31.57%) of middle-aged adults (~40.5 years) with a male/female ratio of 1.1:1. The individuals were mostly symptomatic with a mean evolution time of 9.6 months. Surgical removal plus adjuvant therapy (especially radiotherapy) was the main approach (51.86%). Recurrence was reported in 39.62% of cases. Nodal and distant metastases were identified in 28.26% and 26.66% of cases, respectively. The 2-year cumulative survival rate was 55%. Independent predictors of poor survival were the presence of neurofibromatosis type 1 (p = 0.04) and distant metastases (p = 0.004). The diagnosis of MPNST is challenging due to the variety of its clinical and histopathological presentations. Local aggressiveness and the potential for metastases are common outcomes of this neoplasm.

RESUMO

BACKGROUND: Lymphomas in the oral and oropharyngeal regions are relatively uncommon, and their diagnosis is challenging and complex due to the myriad histopathological subtypes. Herein, we report a large series of oral and oropharyngeal lymphomas and compare our data with the currently available literature. METHODS: All cases diagnosed as lymphomas affecting the oral and oropharyngeal regions were retrospectively retrieved from seven Brazilian institutions. Clinicodemographic data and histopathological features were evaluated and described, while a comprehensive literature review was undertaken in order to compare our findings. RESULTS: A total of 304 cases of oral and oropharyngeal lymphomas were obtained, mostly affecting individuals aged 60-69 years (n = 68) with a mean age at diagnosis of 54.2 ± 20.1 years. Males and females were equally affected. Mature B-cell neoplasms (87.2%) were the most common group, followed by mature T- and NK-cell neoplasms (11.2%) and precursor lymphoid neoplasms (1.6%). The most frequent subtypes in each group were diffuse large B-cell lymphomas, not otherwise specified (n = 99), extranodal NK/T-cell lymphomas, nasal type (n = 12), and B-lymphoblastic leukaemia/lymphomas, not otherwise specified (n = 4). The most commonly involved sites were the palate (26.3%), mandible (13%), and maxilla (10.5%). CONCLUSION: Diffuse large B-cell lymphoma, not otherwise specified, remains the most common subtype of lymphomas in the oral and oropharyngeal region. Older patients are the most affected, with no gender predilection and the palate and jaw are usually affected.

RESUMO

We present a challenging case of HIV-related lymphangioma-like Kaposi sarcoma (LLKS) affecting the oral cavity. A 54-year-old Brazilian male patient was referred to our center complaining of bleeding lesions affecting the oral cavity for 2 months. Interestingly, these oral lesions were the first clinical manifestation of HIV infection. Clinically, multiple erythematous nodular and patch lesions were observed. An incisional biopsy was performed, revealing numerous microscopic angled and irregular vascular channels lined with flattened endothelial cells. More cellularized and solid areas consisting of more fusiform cells with little pleomorphism and with slit-like vascular channels were noted. Based on immunoreactivity for CD31, CD34, D2-40, and HHV-8, the final diagnosis was oral LLKS. Highly active antiretroviral therapy (HAART) was initiated with dolutegravir, tenofovir, and lamivudine. During follow-up, the patient showed KS metastases to other sites and a chemotherapeutic protocol was initiated. Regression of the oral lesion was clearly noted by the clinicians 1 year after the KS diagnosis. Dentists should be able to recognize systemic diseases that affect the oral cavity such as KS in order to make an early diagnosis of its oral manifestations and to implement effective therapeutic measures to ensure a better prognosis.

RESUMO

STATEMENT OF PROBLEM: Brazilian green propolis may be an alternative product that reduces the development of a microbial biofilm on the polymers used for maxillofacial prostheses. However, its effects as a disinfectant have not been fully established. PURPOSE: The purpose of this in vitro study was to investigate the effects of Brazilian green propolis alcohol solutions against the Staphylococcus aureus biofilm on polymers used in maxillofacial prostheses, the maxillofacial silicone elastomer (MDX4-4210), and specific acrylic resins for ocular prostheses. MATERIAL AND METHODS: A total of 324 disk-shaped specimens (3×10 mm) of each material were fabricated. All specimens were contaminated with S. aureus (108 cells/mL) to assess the antibiofilm activity of immersion solutions and protocols. Thus, 162 specimens of each material were randomly distributed and equally divided into 5 groups of disinfectants and 1 control group: 3 separate groups of 2.5%, 5%, and 10% propolis alcohol solutions, 1 group of 5% propolis alcohol gel, a positive control group of 2% chlorhexidine gluconate, and a negative control group of distilled water. Specimens (n=9) were disinfected by immersion for 5, 10, and 15 minutes and immersed in culture medium for 24 hours. Any notable turgescence in the final medium was considered indicative of a biofilm. The effects of disinfectants were analyzed by a turbidity assay and by scanning electron microscopy. Data were analyzed descriptively. RESULTS: The final medium with specimens disinfected with 10% propolis alcohol solution showed no turbidity, indicating constant efficacy against the S. aureus biofilm. Similarly, these findings were observed in the 2% chlorhexidine gluconate group. Scanning electron microscopy images demonstrated that the surface of the polymers treated with 10% propolis alcohol solution did not show bacterial colonies. CONCLUSIONS: Disinfection with 10% green propolis alcohol solution was effective in eliminating the S. aureus biofilm from specimens of maxillofacial elastomer and N1 acrylic resin specific to ocular prostheses by immersion for 5 minutes.

RESUMO

OBJECTIVES: Oral mucositis (OM) is an acute toxicity related to cancer treatment. This systematic review aimed to identify potential risk factors associated with the development of OM in pediatric cancer patients. METHODS: A search was performed in four electronic databases to identify studies that analyzed risk factors for OM in pediatric cancer patients. RESULTS: Nineteen articles were included. The incidence of OM ranged from 20% to 80.4%. Chemotherapeutic agents were potential risk factors for OM in eight (42%) studies. Hematological, hepatic, and renal parameters were also considered in eight (42%) studies, while specific individual factors were reported in five (26.3%) studies. Baseline disease, oral microbiota, genetic profile, and biomarkers were reported in four (21.5%) studies each. Meta-analysis showed that groups submitted to high-risk chemotherapy for OM had a 2.79-fold increased risk of OM. CONCLUSIONS: Identifying risk factors for OM is essential in order to allow individualized and early prevention treatment.

RESUMO

BACKGROUND: The aim of the present systematic review was to analyze the available data regarding acinic cell carcinoma of the oral and maxillofacial region. METHODS: A search strategy was performed using PubMed, Web of Science, Scopus, and Embase electronic databases. RESULTS: Available data revealed a slight female preference (54.73%) and a mean age at diagnosis of 47.51 ± 19.85 years. The parotid glands (67.72%) were most frequently affected, and most cases were asymptomatic (69.54%). A microcystic histopathological pattern was reported in 21.56% of the cases, and the Periodic acid-Schiff was the staining method most frequently used, after the hematoxylin and eosin staining, in the tumors analyzed. The lesions were mainly treated by surgical removal (72.32%). Recurrence was reported in 81 cases (27.83%) and metastasis in 100 (42.91%). Statistical data analysis revealed that tumors located in major salivary glands and exhibiting high-grade histology were associated with local recurrence (P = .01). In addition, the patients older than 57 years, lesions with bone involvement, the high-grade tumors and the cases with a history of recurrence and metastasis were associated with a lower overall survival (P < .05). CONCLUSION: By assembling all eligible cases in the literature, the present systematic review determined the most common clinicopathological profile of acinic cell carcinoma and the most relevant prognostic factors in a distinctly representative sample. The survey demonstrated the importance of considering the histopathological grading in order to better define the treatment for each case.

RESUMO

OBJECTIVE: To systematically integrate the available data published in the literature on oral pigmented lesions (OPL) associated with syndromes, summarizing the clinical and demographic features of the individuals. MATERIALS AND METHODS: An electronic search was undertaken in six databases. Eligibility criteria were articles in English, Spanish, and Portuguese describing case reports or case series of OPL associated with syndromes. Data were aggregated and statistically evaluated. RESULTS: About 108 articles reporting 149 cases of individuals with syndromes were identified. Among the affected individuals, nine syndromes were reported. The mean age at diagnosis was 35.93 years (0.41 to 83 years), with a predilection for white (n = 85/85.86%) female (n = 102/68.46%) individuals. As regards the number of lesions, 109 (73.15%) were multiple and 40 (26.85%) were single. Lip represented the anatomical location more affected (122 cases/38.01%), followed by the buccal mucosa (100 cases/31.15%). Brownish lesions accounted for 82 (69.49%) cases. The mean time of evolution was 10.52 years (0.16 to 56 years). OPL preceding diagnosis of the syndrome was observed in 111 (74.50%) cases. CONCLUSIONS: Although these syndromes are uncommon, dentists should be able to recognize their manifestations, since oral manifestations can represent an important aspect in early diagnosis.

RESUMO

INTRODUCTION: Malignant nonendodontic periapical lesions represent a rare diagnosis, in which few case have been reported about this condition. Due to the low occurrence and little exploration of this subject, serious errors of diagnosis are observed in the oral medicine services. In this sense, the purpose of the present review was to integrate the information on the record published on malignant lesions that mimic endodontic pathoses into a comprehensive analysis of their clinical, radiologic, and histopathologic features. METHODS: An online search was made in March 2020 in the following databases: Pubmed, Web of Science, and Scopus. Eligibility criteria included publications having enough clinical, radiologic, and histopathologic information to confirm the diagnosis. Data were assessed descriptively. RESULTS: Forty-nine publications from 16 countries comprising 60 cases were included. There is a nearly equal occurrence rate between males and females (male/female ratio is 49.15%/50.84%) with a mean age of 46.56 years. The lesions were more prevalent in the posterior mandibles (40.69%), and, radiographically, they were unilocular radiolucent. Histopathologic analysis showed metastasis (26.67%) as the most prevalent lesion followed by salivary gland malignant disease (25%). CONCLUSIONS: The present systematic review revealed several histologic types of malignant periapical lesions that could be mimicking endodontic pathoses. Because these lesions usually do not show clinical or radiologic features of malignant alteration, clinicians should consider these hypotheses in their routine.

RESUMO

OBJECTIVE: The aim of this study was to report the clinicopathologic features of 62 cases of central odontogenic fibroma (COdF). STUDY DESIGN: Clinical and radiographic data were collected from the records of 13 oral pathology laboratories. All cases were microscopically reviewed, considering the current World Health Organization classification of tumors and were classified according to histopathologic features. RESULTS: There were 43 females and 19 males (average age 33.9 years; range 8-63 years). Clinically, COdF lesions appeared as asymptomatic swellings, occurring similarly in the maxilla (n = 33) and the mandible (n = 29); 9 cases exhibited palatal depression. Imaging revealed well-defined, interradicular unilocular (n = 27), and multilocular (n = 12) radiolucencies, with displacement of contiguous teeth (55%) and root resorption (46.4%). Microscopically, classic features of epithelial-rich (n = 33), amyloid (n = 10), associated giant cell lesion (n = 7), ossifying (n = 6), epithelial-poor (n = 3), and granular cell (n = 3) variants were seen. Langerhans cells were highlighted by CD1a staining in 17 cases. Most patients underwent conservative surgical treatments, with 1 patient experiencing recurrence. CONCLUSIONS: To the best of our knowledge, this study represents the largest clinicopathologic study of COdF. Most cases appeared as locally aggressive lesions located in tooth-bearing areas in middle-aged women. Inactive-appearing odontogenic epithelium is usually observed within a fibrous/fibromyxoid stroma, occasionally exhibiting amyloid deposits, multinucleated giant cells, or granular cells.

RESUMO

BACKGROUND: Intravascular papillary endothelial hyperplasia is an unusual vascular lesion characterized by the proliferation of endothelial cells. The aim of this study was to determine the frequency and general features of this lesion. METHODS: Biopsy records of three oral pathology services were reviewed for intravascular papillary endothelial hyperplasia cases from 1959 to 2020. In addition, a systematic review of case reports and case series was carried out in eight electronic databases. RESULTS: Of the 65 205 retrieved cases, 20 (0.03%) were diagnosed as intravascular papillary endothelial hyperplasia. Mean patient age was 46.55 years, and females (12 cases/60%) were more affected. The lower lip (9 cases/47.36%) was the most commonly affected site, and the lesions were generally asymptomatic (7 cases/63.63%). Clinically, 90% of the lesions presented (18 cases) as a nodule, with a mean size of 1.13 cm. The clinical diagnostic hypotheses most frequently raised were mucocele (6 cases/37.50%) and hemangioma (5 cases/31.25%). An excisional biopsy was chosen in all cases for treatment. Forty-nine studies of the systematic review were included, yielding 105 cases. The literature showed similarity in all variables. CONCLUSION: Despite the uncommon frequency, clinicians and oral pathologists should familiarize themselves with the similarities between intravascular papillary endothelial hyperplasia and some other lesions in terms of clinical and histological features.

RESUMO

Liposarcomas of the oral cavity are rare. Those originating in the buccal mucosa cause challenging diagnostic and therapeutic issues since less than 40 cases of liposarcomas of the buccal mucosa and cheek have been reported in the worldwide literature. Herein, we present a case of atypical lipomatous tumor/well-differentiated liposarcoma affecting a 45-year-old female patient. Ultrasonography and magnetic resonance imaging confirmed a well-defined mass located in the right buccal mucosa, extending to the submucosal layers of the cheek. Histopathologically, a well-differentiated fatty neoplasm with presence of prominent stromal inflammatory cells was observed. Multifocally scattered bizarre hyperchromatic stromal cells, some of which multinucleated, were also observed. An immunohistochemical panel comprising vimentin, S-100, CD10, CD34, CD20, CD3, CD68, CD138, MDM2, Ki-67, and P53 was employed to better characterize the lesion. A local recurrence event occurred during a 10-year follow-up period. Surgical resection was performed during both episodes. We also provided an overview of demographic and clinicopathological characteristics, immunohistochemical features, imaging findings, and the differential diagnosis of liposarcoma of the oral cavity. Knowledge of the etiopathological and clinical aspects of this rare neoplasm is fundamental in order to rule out other conditions, including lipomatous lesions that affect the buccal mucosa.

RESUMO

OBJECTIVES: The purpose of this systematic review was to incorporate the information published on metastatic lesions in the in the oral and maxillofacial region into a comprehensive analysis of their demographic, clinical, and imaginological features and survival rate. MATERIALS AND METHODS: An electronic search was undertaken in the subsequent databases: PubMed, Web of Science, Scopus, EMBASE, and LILACS. All papers included were case reports or case series. Absolute and relative frequencies were obtained by descriptive analysis. Overall survival was defined by the Kaplan-Meier method. RESULTS: This systematic review identified 217 studies from 33 countries, comprising 348 cases. Male individuals were more affected (n = 199/57.68%) in the 5th to 7th decades of life. The most usual primary site was the lung in men (n = 49/14.08%) and the breast in women (n = 40/11.49%). Jawbones were affected in 183 cases (53.19%), with the posterior mandible (n = 96/66.66%) representing the preferred site. In soft tissues, the gingiva (n = 80/23.25%) was more affected. Clinical presentation was a nodular mass with or without ulceration (n = 280/85.89%). Imaginological examinations revealed radiolucent/hypodense lesions (n = 115/59.28%). The mean survival time was eight months. CONCLUSION: Despite the rare occurrence of metastatic lesions in the oral and maxillofacial region, the current systematic review offers substantial data that could assist clinicians and surgeons.

RESUMO

The microenvironment of oral cancer is highly dynamic and has been proved to affect tumor progression. Pericytes are blood vessels surrounding cells that have recently gained attention for their roles in vascular and cancer biology. The objective of the present study was to survey the scientific literature for conclusive evidence about whether pericytes are part of blood vessels in oral squamous cell carcinoma (OSCC) and their roles in the tumor microenvironment and clinical outcomes. A systematic electronic search was undertaken in Medline Ovid, PubMed, Web of Science, and Scopus. Eligibility criteria were: publications adopting in vivo models of OSCC that included pericyte detection and assessment by pericyte markers (e.g., α-smooth muscle actin, neuron-glial antigen 2 and platelet-derived growth factor receptor-ß). The search yielded seven eligible studies (from 2008 to 2018). The markers most commonly used for pericyte detection were α-smooth muscle actin and neuron-glial antigen 2. The studies reviewed showed the presence of immature vessels exhibiting a reduction of pericyte coverage in OSCC and indicated that anti-cancer therapies could contribute to vessel normalization and pericyte regain. The pericyte population is significantly affected during OSCC development and cancer therapy. While these findings might suggest a role for pericytes in OSCC progression, the limited data available do not allow us to conclude whether they modify the tumor microenvironment and clinical outcome.

RESUMO

INTRODUCTION: The purpose of this study was to analyze the features of lesions obtained from biopsies at the periapical area of teeth with a radiographic or clinical initial diagnosis of apical periodontitis. METHODS: A retrospective study was conducted on biopsies obtained from 1953-2018 at 3 Brazilian oral and maxillofacial pathology centers. Cases of endodontic and nonendodontic periapical lesions (NPLs) with a clinical diagnosis of endodontic pathoses were retrieved. Data regarding patient age, sex, and anatomic location were obtained from patients' records. The frequency and percentage of cases with clinical diagnoses of a periapical cyst, periapical granuloma, or dentoalveolar abscess were recorded, and the final histopathologic diagnosis was documented. RESULTS: Among 66,179 oral biopsies, 7246 (10.94%) were clinically diagnosed as periapical disease, 306 (4.22%) of which were histopathologically diagnosed as NPLs. The most frequent NPLs were odontogenic keratocysts (n = 107, 34.96%) followed by dentigerous cysts (n = 48, 15.68%). The mean age at diagnosis was 39.68 years with a range of 6-80 years. A total of 159 (51.96%) cases occurred in females and 147 (48.03%) in males (female to male ratio = 1.08:1). Most lesions (137, 44.77%) were located in the posterior mandible. CONCLUSIONS: A wide variety of histopathologic diagnoses, including benign odontogenic and nonodontogenic cystic and tumorous lesions, infectious diseases, and malignant neoplasms, was reported in the present survey. The features presented in this study were consistent with previous findings reported in the literature.

RESUMO

We present the frequency of cases of isolated odontogenic keratocysts submitted to microscopic examination at 10 Brazilian referral centres in Oral and Maxillofacial Pathology. In a retrospective (1953-2017) analysis, data on clinicoradiographic features and treatment of these lesions were collected and analysed descriptively. Among the 258,867 cases retrieved, 2,497 (0.96%) were isolated odontogenic keratocysts. In summary, an overview of individuals affected with isolated odontogenic keratocysts is reported herein. This lesion showed predilection for the posterior mandible of young adult men.

RESUMO

PURPOSE: The aim of this study was to analyze the clinical features of BSCC in the oral cavity, diagnosed over 31 years of service in oral pathology, and make comparisons with the data reported in the literature. METHODS: Data regarding gender, age, clinical presentation, anatomical location, symptoms, evolution time, size of lesion, and use of alcohol and tobacco from cases of BSCC were collected. Additionally, we conducted a review of BSCC studies from searches in three electronic databases. RESULTS: Among 24,570 oral biopsies, 7 (0.03%) were BSCC and represented 0.8% of oral squamous cell carcinoma (n = 875). All cases occurred in males, and the prevalent affected age was the sixth decade (60%). Ulcers occurred in all cases, with the majority showing no symptoms (71.4%). The tongue (30.8%), alveolar ridge/gingiva (30.8%), and floor of the mouth (23.1%) were the anatomical locations affected. The literature review indicated a total of fifteen publications, reporting 214 cases of BSCC. Males (76.7%) in the seventh (53.3%) decade of life were most affected. According to the cases with adequate information, symptomatic (90.0%) ulcers (80.0%) in the floor of the mouth (42.1%), with a mean size of 2 cm and the mean evolution time of 1.5 to 18 months were the most seen. Association with tobacco and alcohol use, when noted, was 50.0%. CONCLUSION: The features presented in this study are more similar than different when compared with the literature data.
