BACKGROUND: Salivary gland neoplasms make about 3 % of all Head & Neck tumours. Thesetumors are uncommon, accounting for 10 to 15% of all salivary gland neoplasms. Unfortunately themajority of such tumours are malignant. The study aims to give an account of the nature of these tumors.PATIENTS AND METHODS: This retrospective descriptive study was conducted in the departmentsof ENT Head & Neck Surgery of two main tertiary care hospitals of Khyber Pukhtoon Khwa i.e. PGMIHayatabad Medical Complex Peshawar and PGMI Govt lady Reading Hospital Peshawar from July2008 to June 2013. Data extracted from charts review of patients contained age, sex, geographicaldistribution, symptoms, histopathological diagnosis, and treatment. Patients presented to thesedepartments with lesions on the palate and who were managed there were included in the audit. Datathus obtained were analyzed using SPSS 16.RESULTS: A total of 46 patients including 19 male and 27 female presented with primary neoplasmsoriginating in the palatal minor salivary glands were enrolled in the audit. These included 11 benign and35 malignant lesions. Most of the patients were Pakistani (29) as compared to Afghani population (17).Patients ranged in age from the second to the eighth decades, with a female preponderance. The mostcommon malignant lesion was mucoepidermid carcinoma followed by adenoid cystic carcinomawhereas in benign category pleomorphic adenoma was more common tumor.CONCLUSION: The vast majority of neoplasms of the minor salivary glands in the palate aremalignant. These should be managed without delay with wide excision and subsequently subjected tohistopathology to arrive at a correct diagnosis..KEY WORDS: Minor salivary glands, neoplasms, palate, malignant, Benign.

Abstract Background Conjunctival lesions are common with a wide spectrum of benign, premalignant, and malignant lesions. Few histopathological studies have been conducted on conjunctival lesions with variable designs and results. Our aim in this study is to provide information on common conjunctival lesions seen in an ophthalmology tertiary care center in Saudi Arabia. Methods A retrospective, observational study of all consecutive conjunctival tissue specimens sent for histopathological assessment to the pathology department from 2015 to 2019 were analyzed. Clinical data were collected from medical records, and the histopathological slides were reviewed by a single pathologist. Results A total of 110 conjunctival specimens from 108 patients were included (mean age: 53 years, 67 males and 43 females). Bilateral involvement was mostly found in inflammatory lesions (40%). Most lesions were benign (91%), with a significantly longer duration of symptoms in malignant lesions (p = 0.036*). The clinical diagnosis matched the final histopathological diagnosis in 75.5% of the total specimens. The most frequent category of benign lesions was fibrodegenerative and proliferative lesions (53.6%), with a significantly higher prevalence among adult males (p < 0.001). Melanocytic lesions were more common in children (33.3%) than adults (9.8%), and the mean age of children was significantly lower (p = 0.013). The most frequent malignant lesion was ocular surface squamous neoplasia (50%), with equal prevalence among males and females. The overall outcome was favorable in 89.4% and unfavorable in 10.6%, mostly due to surgical complications, further progression of the lesion, or recurrence. Conclusion This study shows variability in the frequency of conjunctival lesions based on gender, age, geographical, racial, and environmental factors. There has been a shift in the gender-based prevalence of ocular squamous neoplasia over the last three decades, probably due to a change in lifestyle.

AbstractIntroductionNeurofibromin, a protein encoded by theNF1gene, is mutated in neurofibromatosis 1, one of the most common genetic diseases. Oral manifestations are common and a high prevalence of hyposalivation was recently described in individuals with neurofibromatosis 1. Although neurofibromin is ubiquitously expressed, its expression levels vary depending on the tissue type and developmental stage of the organism. The role of neurofibromin in the development, morphology, and physiology of salivary glands is unknown and a detailed expression of neurofibromin in human normal salivary glands has never been investigated.AimTo investigate the expression levels and distribution of neurofibromin in acinar and ductal cells of major and minor salivary glands of adult individuals without NF1.Material and methodTen samples of morphologically normal major and minor salivary glands (three samples of each gland: parotid, submandibular and minor salivary; and one sample of sublingual gland) from individuals without neurofibromatosis 1 were selected to assess neurofibromin expression through immunohistochemistry. Immunoquantification was performed by a digital method.ResultsNeurofibromin was expressed in the cytoplasm of both serous and mucous acinar cells, as well as in ducts from all the samples of salivary glands. Staining intensity varied from mild to strong depending on the type of salivary gland and region (acini or ducts). Ducts had higher neurofibromin expression than acinar cells (p = 0.003). There was no statistical association between the expression of neurofibromin and the type of the salivary gland, considering acini (p = 0.09) or ducts (p = 0.50) of the four salivary glands (parotid, submandibular, minor salivary, and sublingual gland). Similar results were obtained comparing the acini (p = 0.35) and ducts (p = 0.50) of minor and major salivary glands. Besides, there was no correlation between the expression of neurofibromin and age (p = 0.08), and sex (p = 0.79) of the individuals, considering simultaneously the neurofibromin levels of acini and duct (n = 34).ConclusionNeurofibromin is expressed in the cytoplasm of serous and mucous acinar cells, and ductal cells of salivary glands, suggesting that this protein is important for salivary gland function.

Clinicopathological Study

AbstractThe major salivary glands are considered to rarely be the sites of primary terminal duct adenocarcinomas, a neoplasm with a considerable predilection for origin from intraoral minor salivary glands. We present a clinicopathological study of 22 terminal duct adenocarcinomas of the parotid gland, the largest single series to date. A comparison between the parotid neoplasms and over 200 minor salivary gland terminal duct adenocarcinomas indicates there is little difference in biological behaviour and confirms the low-grade quality of the carcinomas, regardless of site of origin.

Gland Function

The salivary glands consist of three paired major glands—parotid, sub­mandibular, and sublingual—and the countless minor salivary glands found in almost every part of the oral cavity, except the gingiva and anterior regions of the hard palate. The secretion of saliva is essential for the normal function and health of the mouth, and disorders of salivary gland function predispose to oral disease. Functional disorders in salivary secretion may be associated with primary salivary gland disease but in other cases are a consequence of systemic factors, such as medi­cations, endocrine disturbances, and neurological disease, which are discussed in Chapter 10. Developmental anomalies of the salivary glands are rare. Aplasia of one or more major glands and atresia of one or more major salivary gland ducts have been reported. Congenital aplasia of the parotid gland may be associated with other facial abnormalities, e.g. ectodermal dysplasia, mandibulofacial dysostosis, and hemifacial microsomia. Heterotopic salivary tissue has been reported from a variety of sites in the head and neck region, the most frequent being its inclusion at the angle, or within the body, of the mandible, called a Stafne bone cavity. It is usually an incidental radiological finding and appears as a round or oval, well-demarcated radiolucency between the premolar region and angle of the jaw, and is typically located beneath the inferior dental canal. The radiographic appearances are due to a saucer-shaped depression or concavity of varying depth on the lingual aspect of the mandible, which contains salivary tissue in continuity with the submandibular gland. Accessory parotid tissue within the cheek or masseter muscle is rela­tively common and is subject to the same diseases that may affect the main gland. Age changes can be detected in both major and minor salivary glands. Reduction in the weights of submandibular and parotid glands has been reported with increasing age, associated in the submandibular gland with an age-dependent reduction in flow rates. By contrast, sev­eral studies have demonstrated that there is no significant reduction in parotid flow rates in the elderly.

Recommended Treatment

Pleomorphic adenoma is the most common neoplasm in major and minor salivary glands. It constitutes approximately 90% of all benign salivary gland lesions and the parotid is the most affected location. When the minor salivary glands are affected, it mostly occurs at the junction of the hard and soft palates. The diagnosis is complex because of the great histological variety and biological behavior of this tumor, a histopathological examination being essential. The recommended treatment is surgical excision. For lesions located superficially in the parotid gland, superficial parotidectomy - identifying and preserving the facial nerve - is necessary. Lesions in the palate or gums sometimes demand a margin of safety, being excised below the periosteum, including the overlying mucosa. With correct surgical removal, the prognosis is excellent. The aim of this study is to report a case of an unusual minor salivary gland pleomorphic adenoma in the hard palate, describing the most important aspects of this pathology.

AbstractSalivary gland tumors account for less than 3% of the head and neck tumors. Among various salivary gland tumors, pleomorphic adenoma is most common and accounts for 60- 70% of the benign tumors of salivary glands. However, the involvement of minor salivary glands of buccal mucosa is extremely uncommon and reported to be 4% only. Salivary glands may present with a diverse range of lesions presenting a challenge to even the most experienced clinician. We report two rare cases of pleomorphic adenoma of minor salivary glands of buccal mucosa in a 45 year old female and 70 years old male respectively. It includes clinical features, diagnosis and treatment of the tumor.

Abstract Backgrounds The organization of minor salivary glands (MSG) infiltrates, in patients with Sjögren’s syndrome (SS), associates with disease severity and progression. Aberrant regulation of lymphocyte autophagy is involved in autoimmunity, and in previous work, we provided the first evidence of upregulated autophagy in CD4+ T cells infiltrating SS MSG. The aim of this study was to further explore autophagy in SS infiltrating and circulating lymphocytes and to investigate its role in disease histopathological progression. Methods After collection of 20 SS MSG, the presence of lymphocyte aggregates (foci) and the formation of germinal center (GC)-like structures were observed by H&E and confirmed by immunohistochemistry. The expression of autophagy-related genes, Atg5 and MAP1LC3A, was detected by RT-PCR on microdissected salivary gland tissue and control tonsils. In MSG and tonsils, autophagic lymphocytes were identified by the detection of the autophagosome protein LC3B visualized as LC3 puncta staining by immunofluorescence. Peripheral blood autophagy was assessed by flow cytometry in SS and healthy controls (HC). Results Real-time PCR demonstrated higher expression in the autophagy genes Atg5 and MAP1LC3A in MSG GCs as compared to both small foci (p = 0.0075, p = 0.0002) and GCs from tonsils (p = 0.0001, p = 0.0037). In MSG, LC3 puncta staining was detectable on both CD3+ and CD20+ lymphocytes; in tonsils, LC3 puncta was almost undetectable on all lymphocytes. Compared to HC (n = 20), flow cytometry did not reveal any increase of autophagy in SS circulating lymphocytes (n = 30). Conclusions In SS MSG, lymphocytes’ autophagy is a feature of infiltrating T and B cells and is associated with histological severity. Interestingly, in MSG aberrant regulation of autophagy is detectable in GC-like structures possibly indicating its involvement in the development and persistence of the autoimmune process within the lesions.
