    Oral neural tumors (ONTs) are rare lesions and represent reactive or neoplastic proliferations of nerve sheath cells. The purpose of the present study is to report the clinical, demographic and histopathologic features of 157 ONTs diagnosed in a single Oral Pathology Department and review the pertinent literature. 157 cases of ONTs diagnosed during a 44-year period were retrospectively collected and the diagnosis was reconfirmed by studying representative haematoxylin and eosin stained tissue sections. The patients? gender and age, as well as the main clinical features of the lesions, were retrieved from the biopsy submission forms. The 157 ONTs represented approximately 0.4% of 35,590 biopsies accessioned during the study period. They affected 71 male and 86 female patients with a mean age of 38.4±18.8 years. They mainly appeared as asymptomatic nodules of normal or white colour on the tongue, lip mucosa and hard palate. The most common ONT was granular cell tumour (38.9%) followed by neurofibroma (19.7%), schwannoma (15.9%), traumatic neuroma (15.9%), palisaded encapsulated neuroma (8.3%) and nerve sheath myxoma (1.3%). This study confirmed the rarity of ONTs. Their clinical characteristics mimic other oral lesions; thus, microscopic examination is the only mean to arrive at a definitive diagnosis

    Synchronous occurrence of two lateral periodontal cysts in the same patient. Report of a rare case and review of the literature

    Get PDF
    We present a case of a patient with two lateral periodontal cysts in the maxilla and the mandible, respectively, and review the English literature on multiple lateral periodontal (LPCs) cysts and/or gingival cysts (GCs) and botryoid odontogenic cysts (BOCs). The patient was a 59 year-old female with two fluctuant swellings covered by semi-lucent mucosa on the attached gingiva between the maxillary and mandibular right canine and first premolar teeth, respectively. Periapical radiographs revealed at the respective sites between the roots of the canine and first premolar teeth areas unilocular radiolucencies. Intra-operatively, the presence of bone cavities was confirmed at both sites. The microscopic features were consistent with LPC. The review of the English literature on multiple LPCs and/or GCs and BOCs found seven reports of multiple LPCs, four of multiple GCs, and two with an LPCs and a GC. It is concluded that multiple LPCs have been rarely reported in the literature, but should be included in the differential diagnosis of multifocal radiolucencies lateral to vital teeth. The possibility of multiple lesions in different locations should direct to a thorough clinical and radiographic examination in a patient diagnosed with an LPC or GC

    Background: The purpose of this study was to evaluate the immunohistochemical expression of NF-κB and IL-6 in oral premalignant and malignant lesions and to investigate their possible correlation with the presence of subepithelial inflammation. Material and Methods: Thirty two oral premalignant lesions, clinically compatible with leukoplakia or erythroplakia, were investigated. Microscopically, 11 of them showed hyperkeratosis and acanthosis (epithelial hyperplasia) and 21 showed dysplasia of varying degrees. Nine cases of OSCC and four control cases of normal oral mucosa were also included in the study. Immunohistochemical staining with NF-κB (p65) and IL-6 was performed. IL-6 and nuclear NF-κB staining were assessed as positive or negative. For cytoplasmic localization of NF-κB, a total score combining intensity and percentage of positive epithelial cells was additionally calculated. The presence of inflammation was also recorded. Results: Intensity and total scores for NF-κΒ cytoplasmic immunostaining showed a statistically significant gradual increase from normal mucosa to OSCC (p=0.012 and p=0.026 respectively). Non-statistically significant increased NF-κΒ nuclear localization was detected in dysplasias and OSCCs. Positive statistical correlation was detected between the presence of inflammation and IL-6 expression (p=0.015). No correlation between NF-κΒ and IL-6 was detected. Conclusions: NF-κΒ is activated in the early stages of oral carcinogenesis. IL-6 may have an NF-κΒ-independent role, possibly through regulation of the inflammatory response

    Chronic Osteomyelitis With Proliferative Periostitis of the Mandible in a Child Report of a Case Managed by Immunosuppressive Treatment:Report of a Case Managed by Immunosuppressive Treatment

    Background: Osteomyelitis with proliferative periostitis is a relatively uncommon inflammatory condition of the jaws, mainly characterized by periosteal formation of reactive bone. It primarily affects children and adolescences, also referred to as Garre's osteomyelitis, more frequently involving the molar region of the mandible. Cases lacking an obvious source of infection may have an immunologically mediated etiopathogenesis, falling under the spectrum of primary chronic osteomyelitis or chronic recurrent multifocal osteomyelitis (CRMO). Case report: Herein, we present a case of chronic osteomyelitis in a 6.5-year-old girl, who suffered from recurrent painful episodes of swelling of the mandible for the last 2 years, previously requiring hospitalization and administration of intravenous (IV) antibiotics and NSAIDs with limited responsiveness. The biopsy showed features consistent with osteomyelitis with proliferative periostitis. The patient was initially managed with an IV combination antibiotic regimen with only partial improvement. The possibility of an autoimmune mechanism in the context of primary chronic osteomyelitis or CRMO was considered, and immunosuppressive therapy (TNF inhibitor etanercept along with corticosteroids and methotrexate) was administered, resulting in clinical resolution. Conclusions: Osteomyelitis and its childhood variants are relatively rare and their management presents several challenges. Although typically treated with administration of antibiotics, possibly along with surgical intervention, other treatment modalities may be necessary for resilient and persistent cases. In a subset of cases, especially in the absence of local infectious factors, immunologically mediated mechanisms may play an important role and appropriate immunosuppressive therapy may be effective

    Transient lingual papillitis: a retrospective study of 11 cases and review of the literature

    Get PDF
    Transient lingual papillitis (TLP) is a common, under-diagnosed, inflammatory hyperplasia of one or multiple fungiform lingual that has an acute onset, and is painful and transient in nature. Eleven cases of TLP were diagnosed based on their clinical features. Information on demographics, clinical characteristics, symptoms, individual or family history of similar lesions, medical history, management and follow-up were extracted from the patients’ records. The English literature was reviewed on TLP differential diagnosis, pathogenesis and management. The study group included 8 females and 3 males (age: 10-53 years, mean age 31.7±12.88 years). Seven cases were classified as generalized form of TLP and 4 as localized form. Nine cases were symptomatic. Time to onset ranged from 1 to 14 days. A specific causative factor was not identified in any case and management was symptomatic. Although TLP is not considered as a rare entity, available information is limited. Diagnosis is rendered clinically, while biopsy is required in cases with a differential diagnostic dilemma. TLP should be included in the differential diagnosis of acute, painful tongue nodules

    To investigate the relative frequency of localized mucosal swellings of the upper and lower labial mucosa, the clinical-pathological diagnosis agreement and whether patient?s age and gender and tumor?s site and size may raise the suspicion of neoplasm. Retrospective analysis was performed on upper or lower labial mucosal tumors, histopathologically diagnosed between 2009-2018. The diagnostic categories developmental/reactive tumors, benign and malignant neoplasms were associated with patient?s age and gender and tumor?s site and size; clinical-pathological diagnosis agreement was, also, evaluated. Overall, 1000 (95.7%) developmental/reactive tumors, 35 (3.3%) benign and 10 (1%) malignant neoplasms were found. Upper/lower lip tumor ratio was 0.14:1. The diagnostic category was significantly associated with age (p1cm were independent predictors for neoplasms. Patients presenting 2 or 3 of these variables were 20.2 times (p?1cm in patients?60 years have significantly higher probability to be neoplasms

    A randomized clinical trial of topical dexamethasone vs. cyclosporine treatment for oral lichen planus

    Oral lichen planus (OLP) is a common, frequently symptomatic, immune-mediated disease. Various treatments have been used for symptomatic OLP, including corticosteroids and immunosuppressants administered topically or systemically. The aim of this study was to compare the effectiveness of topical dexamethasone vs. topical cyclosporine in treatment of symptomatic OLP. Thirty-two patients with biopsy-proven symptomatic OLP were randomly assigned to two therapeutic groups: dexamethasone 2mg/5ml or cyclosporine 100mg/ml, both administered topically in a swish and spit method three times a day for 4 weeks. The patients were followed up for a total of 6 months. Assessed parameters included clinical scoring (according to Thongprasom?s scale, 0-5), pain (VAS scale, 0-10), dysphagia and speech difficulties (none, mild or severe). Possible side effects, including fungal overgrowth, were also recorded. At the end of the 4-week treatment period, both dexamethasone and cyclosporine showed a statistically significant improvement in clinical scoring (p<0.025 and p=0.034, respectively), which was better with dexamethasone (p=0.001). In addition, both dexamethasone and cyclosporine induced statistical significant improvement in pain and dysphagia (and speech difficulties for dexamethasone), without significant differences between the two groups. Regarding side effects, patients in the dexamethasone group developed candidiasis more frequently compared to cyclosporine (p=0.031). At the end of the 6-month follow-up period, the difference in response between the two groups was not statistically significant. Interestingly, a trend for further improvement compared with the end of the 4-week treatment period was noticed only for patients treated with cyclosporine. Despite the small number of enrolled patients, topical cyclosporine treatment induces a significant clinical improvement in symptomatic OLP patients, which, compared to topical dexamethasone, appears to be less pronounced during initial administration, but capable to induce further improvement after discontinuation with a satisfactory long-term remission in the absence of significant side effects. This study may contribute to a better understanding of the differences in effectiveness of OLP topical treatments and guide future larger scale clinical trials
