HISTOPATHOLOGICAL SPECTRUM OF SALIVARY GLAND TUMOURS: A HOSPITAL BASED STUDY

Background: Salivary gland tumors are common neoplasms of head and neck region. These tumors are complex andsome of them exhibit great deal of morphologic overlap .The majority of these neoplasms are benign. These tumours can occur in both major and minor salivary glands. 80% of major salivary gland tumoursoccur in the parotid glands, while most minor salivary tumours are located in the palate. As a general rule in clinical practice, the smaller the salivary gland is, the more likely the tumouris malignant. Objective: This study was carried out to study the histopathological spectrum of salivary gland tumors and to know their pattern of distribution. Material and Methods:-This is a two year retrospective study which was conducted in the Post graduate department of pathology Government Medical College Srinagar from January 2015 to December 2016 . Post surgical specimens were studied in detail to know the histological patterns. In each patient, age, sex, site and histopathological diagnosis was seen from record section of the department. The histological diagnosis of each individual tumor was based on the 2005 WHO classification of salivary gland tumors. Results:- During two year ( from January 2015 to December 2016), 100 cases of salivary gland tumors were diagnosed with peak incidence in third to fourth decade (48%).Among these, 63(63%) cases were benign and 31(31%) cases were malignant. The commonest site was parotid gland (68%) followed by submandibular glands(19%) and minor salivary gland tumors were 13%. Among benign tumours of salivary glands pleomorphic adenoma (42%) was most common followed by Warthintumour (12%),basal cell adenoma (7%) andMyoepithelioma (2%) and among malignant tumours,Mucoepidermoid carcinoma (46%) was most common followed by Adenoid cystic carcinoma (32.5%), Carcinoma ex pleomorphic adenoma (10.8%), Acinic cell carcinoma and Polymorphous low grade adenocarcinoma each comprising of (5.4%). Conclusion: Histopathological study of salivary gland lesions is the most important method in establishing the final diagnosis and accordingly guides in the specific management.

Histomorphological spectrum of salivary gland tumors: a study at tertiary care teaching hospital of North Gujarat

Tropical Journal of Pathology and Microbiology, 2018

Background: Salivary gland tumors (SGTs) are rare neoplasm of head and neck region. The salivary gland tumours vary widely in histopathological appearance. Also, epidemiological data of these tumors in various parts of the world are different. And so the study of SGTs for their biology and clinical characteristics can be helpful for a better understanding. Objectives: The objective of this study was to study types and new entities, common site of distribution and histomorphological spectrum of salivary gland tumors (SGTs). Materials and Methods: It was a retrospective followed by prospective study. Pertinent clinical history like age, duration of the lesion, site of the lesion, significant family and personal history, history of associated diseases was recorded. Specimens consisted of incisional biopsies were examined microscopically by the expert pathologist. Details of specimens noted in Performa include dimensions, appearance of external and cut surface and presence of lymph nodes, their size and number. Observations: Total 70 cases of SGTs could be included in the study. Among them 56 (80%) were benign and 14 (20%) were malignant. Parotid is commonest salivary gland involved with 75.71% of all tumors, followed by submandibular with 21.42% and minor salivary glands with 1(1.4%) of salivary gland tumors. among benign tumors Pleomorphic adenoma is most common with 70% of all benign SGTs followed by Warthin tumors (7%). Among malignant tumors commonest is Mucoepidermoid carcinoma with 14.28% of all SGTs. Female preponderance was clearly found in malignan at SGTs. Conclusion: Parotid is most common site for the SGT. And pleomorphic adenoma and the Warthin tumors are the common benign tumors involve parotid gland the most. Among malignant tumors mucoepidermoid carcinoma are the commonest with female preponderance. While other carcinoma like adenoid cystic carcinoma and SCC are also common.

Retrospective study of 124 cases of salivary gland tumors and literature review

Journal of Clinical and Experimental Dentistry

Background: Salivary gland tumors are a rare and morphologically diverse group of lesions and their frequency is still unknown in several parts of the world. The knowledge of its population characteristics contributes to a better understanding of its etiopathogenesis. Objectives: This study investigated the frequency of salivary gland tumors in a region of southern Brazil and compared these data in a literature review. Material and Methods: A retrospective study was conducted of salivary gland tumors diagnosed at two pathology centers from 1995 to 2016. Patient age and gender, tumor site and frequency, histopathological diagnosis, and symptomatology were evaluated. Chi-squared tests were used to assess the associations between variables. To compare our data, we also conducted a literature review of publications in the PubMed and LILACS databases of retrospective studies of salivary gland tumors. Results: A total of 124 salivary gland tumor cases was identified, 81 (65.3%) of which were classified as benign and 43 (34.6%) as malignant. Most tumors occurred in the parotid gland (57.2%). Pleomorphic adenoma was the most common tumor (59.6%), followed by adenocarcinoma not otherwise specified (8.8%). The tumors occurred more often in women (54.8%) than in men (45.2%). Malignant tumors were associated with pain in 31.4% of cases (p <0.05). The literature review included 35 articles from different countries. Women were most affected, with a mean age of 41.7 years. The most common benign tumor was pleomorphic adenoma (48.2%) and the most common malignant tumor was mucoepidermoid carcinoma (8.7%). Conclusions: The results of the present study showed that salivary gland tumors are rare. The parotid gland is the most common location and pleomorphic adenoma are the most frequent lesions. The malignant tumors presented as several histological types and the incidence was variable globally.
