Histopathological spectrum of salivary gland lesions  in Ajmer region, Rajasthan, India

Background: There is a wide spectrum of salivary gland lesions with morphological and clinical diversity which makes it a difficult task for histopathological interpretation. Tumours of salivary glands are uncommon accounting for 3-10% of the total tumors of head and neck region and less than one percent of all tumours. The aim of this study was to recognize various histomorphological patterns of salivary gland lesions, their frequency, age, gender and site wise distribution.Methods: This study was carried out from June 2015 to May 2018 in the department of Pathology, JLN Medical College and associated Group of Hospitals, Ajmer. Total 121 cases of salivary gland lesions were included. Specimens were processed and stained by Hematoxylin and Eosin stain followed by histopathological examination.Results: Out of total 121 cases, 43.8% were non-neoplastic and 56.2% were neoplastic. In non-neoplastic lesions predominant was chronic sialadenitis (50.9%) followed by mucocele (28.3%) which commonly seen in submandibular gland (47.17%). Among neoplastic cases, 79.4% were benign and 20.6% were malignant lesions. Neoplastic lesions commonly were seen in parotid (75%). Pleomorphic adenoma was the commonest benign tumour (81.4%). Mucoepidermoid carcinoma was the most common malignant salivary tumour. Benign tumours were common in third and fourth decades, whereas malignant tumours were more common in fifth and sixth decades. Male predominance was seen in overall salivary gland lesions.Conclusions: Histopathological examination is mandatory in the diagnosis of salivary gland lesions because of their wide spectrum of histomorphology.

Salivary gland tumours account for 2-6.5% of all the neoplasms of the Head and Neck. Histopathology is most important in diagnosis of salivary gland tumors. AIMS and OBJECTIVES : To study age,sex and site distribution of various salivary gland lesions, to study the histomorphologic (gross &microscopic) aspect of these lesions to correlate clinical diagnosis with that of histopathologic features. MATERIALS AND METHODS: The study is conducted in the RAINBOW CLINICAL LABORATORY AND RESEARCH CENTRE, SIDDIPET during the period of September2018 to September 2020. Formalin fixed ,paraffin embedded sections and stained with hematoxylin and eosin slides were studied. RESULTS: Total number of specimens were 54. Out of these 39 were neoplastic (benign 70%,malignant 30%) and 15 were non neoplastic. Among the benign tumors majority are pleomorphic adenoma.Among the malignant tumors, mucoepidermoid carcinoma is the most common. Among the non neoplastic lesions chronic sialadenitis is most common. CONCLUSION: Histopathological examination of salivary gland lesions stands out to be the most important method in establishing the final diagnosis. It helps in differentiating non neoplastic and neoplastic lesions.

Background: Fine needle aspiration cytology (FNAC) has been used for diagnosis of salivary gland lesions for many years. Various studies in the existing literature have shown a wide range of sensitivity and diagnostic accuracy of cytologic diagnosis. FNAC is a safe, simple, cost effective, 1-4 accurate and minimal invasive procedure for the evaluation of salivary gland lesions. FNAC is not only useful in planning denitive preoperative 2,5-6 diagnosis but also can prevent unnecessary surgical intervention. Salivary gland swelling occur more commonly in 3rd decade of life with equal sex incidence. Parotid is one of the most commonly involved glands in the head & neck region swellings. FNAC appears to be highly sensitive for benign tumours and highly specic for malignant tumors and it should be the rst line of investigation in evaluating the salivary gland pathologies. 7 Early diagnosis and appropriate management carries good prognosis. Methods: Patients with suspected salivary gland enlargements, referred for FNAC, were included in this study. FNAC was performed by using the standard procedure. Cytologic diagnosis was compared with histopathologic diagnosis wherever it was available. Results: In the present study conducted in the department of pathology, Shyam Shah Medical College Rewa MP, over a period of 5 years, 152 Patients with suspected salivary gland enlargements were retrospectively appraised. The benign lesions of salivary gland were 133 (87.5%), out of which Pleomorphic adenoma was diagnosed in 75 (56.39%) cases, clinical correlation was found in 58 (77.33%) cases. 29 cases were subsequently correlated with histopathological examination 26 correctly correlated and the diagnostic accuracy of FNAC was found to be 89.65%. Inammatory lesions were proved correct in 08 out of 10 cases after histopathology. Therefore, accuracy of FNAC was 80.0%. Malignant lesions of salivary gland were found in 19 cases, out of which 15 (78.94%) cases correlated with clinical diagnosis. 13 cases were subjected to histopathology 10 correctly correlated and the diagnostic accuracy of FNAC was found to be 76.92%. Overall diagnostic accuracy of FNAC was 84.61%. Conclusion:In conclusions it can be established that FNAC is an efcient and accurate procedure with high sensitivity index, and its usefulness is enhanced due to it being a relatively easy procedure which can be carried out even on outdoor patients.

BACKGROUND A variety of non - neoplastic and neoplastic conditions involve the nasal cavity, paranasal sinuses and nasopharynx and these are very common lesions encountered in clinical practice. Histopathological examination of these lesions is the gold standard for diagnosis because management and prognosis vary among different lesions. The aim of the present study was to evaluate the histopathological study of the lesions of the nasal cavity, paranasal sinuses and nasopharynx in relation to their incidence, age, gender and site wise distribution and to compare the results with the available data. METHODS A study of 88 cases was conducted for a period of 2 years from August 2017 to July 2019. After fixation, Processing and Haematoxylin and Eosin staining and special stains histopathological diagnosis was made. RESULTS Among 88 total cases, 58 were males and 30 were females. A male predominance was observed with a male to female ratio of 1.93 : 1. They were more common in third, fourth and fifth decade of life. Malignant nasal lesions were seen after fourth decade of life. Nasal lesions were more common in nasal cavity (67.05 %), followed by paranasal sinuses (18.18 %) and nasopharynx (14.75). Out of 88 total cases, 39 (44.32 %) were non - neoplastic, 30 (34.09 %) were benign and 19 (21.59 %) were malignant nasal lesions. CONCLUSIONS Sinonasal lesions and nasopharyngeal lesions can have various differential diagnoses. A complete clinical, radiological and histopathological correlation helps to categorize these sinonasal lesions into various non - neoplastic and neoplastic types. But histopathological examination remains the mainstay of definitive diagnosis.

Abdominal Masses

Intra-abdominal masses in children are usually malignant. Benign tumours at this location are not seen frequently. It is even rarer to find solitary myofibromas intra-abdominally as these tumours are known to have predilection for the head and neck region. We present an unusual case of solitary myofibroma with abdominal localisation in a six-year-old male child who presented with abdominal distension since six months. Computed Tomography (CT) abdomen revealed a complex solid-cystic mass extending from umbilicus to right iliac fossa and measuring 9×6×4 cm. Histopathological examination revealed a tumour displaying biphasic nodular pattern with the presence of lighter staining fascicles of mature myoid cells along with darker staining and more cellular areas of smaller primitive cells. On Immunohistochemistry (IHC), tumour cells were positive for vimentin and Smooth Muscle Actin (SMA) with variable reactivity for desmin while these were negative for CD34 and Anaplastic Lymphoma Kinase 1 (ALK). Based on the histopathological and immunohistochemical findings, final diagnosis of myofibroma was made. Recognition of these lesions is extremely challenging owing to their rare presentation intra-abdominally and also because of their close morphological overlap with other spindle cell tumours commonly found at this site. This case highlights the combined role played by histopathology and IHC in making a clear distinction between different entities. It is imperative for both clinicians and histopathologists to establish the correct diagnosis as excision of the solitary myofibroma is curative in most cases and offers better clinical course than the more commonly found malignant tumours at this site.

BACKGROUND The incidence of testicular malignancy has been increasing in men, orchidectomy is necessary for the removal of neoplastic lesions or in patients with chronic inflammatory conditions resistant to treatment. We wanted to evaluate the various histopathological patterns of lesions in testis. METHODS A retrospective study of 86 orchidectomy specimens over a period of three years with age wise distribution from March 2017 to February 2020 was done in the Department of Pathology, Guntur Medical College, Guntur. Histopathological slides stained with haematoxylin and eosin were retrieved and reviewed. Immunohistochemistry was done in two cases. RESULTS Of the 86 cases, 78 (90.7 %) cases were non neoplastic and 8 (9.3 %) cases were neoplastic. Youngest age in non-neoplastic group was four days and in neoplastic group was 18 years. The oldest age was 82 years in the non-neoplastic lesions and 60 years in the neoplastic lesions. Non neoplastic lesions were common in the 3 rd decade. In malignant lesions, highest number of cases was seen in the 6 th decade and equal distribution was observed in 3rd and 5th decade. Unilateral involvement was common than bilateral involvement. Out of all non-neoplastic lesions, undescended testis 20 (25.64 %) cases was the common finding followed by non-specific epididymo orchitis 19 (24.36 %) cases, abscess 14 (17.95 %) cases, torsion infarction 13 (16.67 %) cases, Leydig cell hyperplasia 4 (5.13 %) cases, 3 (3.85 %) cases each of tuberculous epididymo orchitis and granulomatous epididymo orchitis. 1 (1.28 %) case each of rare entities like vanishing testis and splenogonadal fusion were also found. Among the neoplastic lesions, all 8 cases were malignant tumours. Out of these malignant tumours, mixed germ cell tumours were seen in 3 (37.5 %) cases followed by seminomas 2 (25 %) cases, post pubertal teratoma 1 (12.5 %) case, non-Hodgkin’s lymphoma (NHL) 1 (12.5 %) case and primitive neuroectodermal tumour (PNET) 1 (12.5 %) case. CONCLUSIONS Histopathological examination on routine haematoxylin and eosin (H&E) stained sections primarily differentiate non neoplastic lesions from neoplastic group and benign tumours from malignant tumours as the treatment modality varies. Immunohistochemistry (IHC) is useful in the diagnosis of poorly differentiated small round cell tumours. KEYWORDS Orchidectomy Specimens, Neoplastic and Non-Neoplastic Lesions

Abstract Background: Salivary gland lesions, especially the neoplastic lesions constitute a highly heterogeneous histopathologic group. Several studies have reported a significant difference in the global distribution of salivary gland tumors, but no formal study has been carried out in this part of the globe. Objectives: To document the pattern of various salivary gland tumors in Manipur, a state in North Eastern India. Materials and Methods: This is a 10 years (2002-2011) retrospective study of all salivary gland specimens received at our referral teaching hospital in Manipur, India. All the histopathology slides of salivary gland specimens during the study period were reviewed and clinical details were obtained from the archives. Restaining of slides and fresh sections of tissue blocks were performed whenever required. Data thus collected were analyzed. Results: A total of 104 cases of salivary gland lesions were studied during the study period. Age ranged from 5 years to 78 years with an overall slight female preponderance (M:F = 1:1.08). Parotid (56.65%) was the commonest gland involved followed by submandibular gland (31.73%). Neoplastic lesions comprised of 78 (75%) cases and non-neoplastic lesions constituted 25% (26 cases). Among the neoplastic lesions, benign lesions (53.85%) predominated over malignant lesions (21.15%). Pleomorphic adenoma was the commonest benign neoplastic lesion and mucoepidermoid carcinoma was the commonest malignant tumor. Chronic sialadenitis was the predominant lesion in the non-neoplastic group. Conclusion: The principal site for salivary gland tumors was the parotid gland and pleomorphic adenoma outnumbered all the other tumors. Females are more affected in the malignant group.

Background: Salivary gland tumors (SGT) are uncommon tumors of diverse histopathology accounting for <2% of all neoplasms. Early diagnosis differentiates between benign and malignant SGT and less extensive surgical procedure can be performed. The objective is to study the spectrum of primary SGT with special emphasis on their distribution, treatment and outcome at a rural tertiary care centre.Methods: A prospective observational study was conducted on 30 consecutive primary SGT patients attending the Departments of Surgery and Otorhinolaryngology of North Bengal Medical College and Hospital over a period of one and half years. All patients were clinically evaluated, investigated, treated accordingly and followed up during the period of study. Data was collected and compiled in Excel sheet and analysed using GraphPad Software and GraphPad QuickCalcs 2018 (San Diego, CA). A p value <0.05 was considered statistically significant.Results: Maximum patients (83.3%) were in the age range of 31-60 years. The male to female ratio was 1:4 for benign tumours and 1:1 for malignant tumours. Malignant cases were 66.67%. Involvement of parotid gland was the commonest (43.3%) and mostly presented with swelling (73.3%). Pleomorphic salivary adenoma was the commonest benign tumor (33.3%) and mucoepidermoid carcinoma was the commonest malignant tumor (16.7%). Permanent facial palsy was observed in 2 (9.5%) and recurrence in 4 patients (19%).Conclusions: SGT are rare and present in various modes. Malignant cases were singularly more in this study.
