The origin of a salivary gland tumour is attributed to cells at various levels of differentiation which present histologically as diverse tissues and cellular patterns. Mitochondria-rich, eosinophilic oncocytes are cells commonly encountered in salivary gland neoplasms. We report a case of mucoepidermoid carcinoma (MEC) in the palate of a 43-year-old female that exhibited a prominent oncocytic component. While the parotid and submandibular glands have been reported as predominant sites for oncocytic MEC (OMEC), the palate and minor salivary glands are rare sites for occurrence. Also, most of the reported cases of OMEC have been histologically of low-grade mucoepidermoid carcinoma with large cystic spaces and good prognosis. In this article, we discuss the differential diagnosis and diagnostic workup of an MEC presenting with oncocytes.

Objectives Kallikrein-related peptidase 10 (KLK10) has been implicated in the development of several types of cancer. The purpose of this study was to analyze the expression of KLK10 in 3 types of salivary gland tumour and normal salivary glands. Materials and methods: A standard immunoperoxidase staining technique was used to assess the Immunoexpression profile of KLK10 in normal salivary glands and 3 types of salivary gland tumour: pleomorphic adenoma, adenoid cystic carcinoma and mucoepidermoid carcinoma. Results Pleomorphic adenomas showed significantly lower KLK10 levels than control tissues. Neither of the malignant tumours (adenoid cystic carcinoma and mucoepidermoid carcinoma) showed a significant alteration in the immunoreactive scores of KLK10 in comparison with the normal salivary gland tissues. KLK10 immunoreactive scores were comparable in adenoid cystic carcinoma and mucoepidermoid carcinoma. Pleomorphic adenoma had significantly lower levels of KLK10 than mucoepidermoid carcinoma. Conclusions The finding of lower KLK10 levels in pleomorphic adenoma suggests aberrant expression in a tumour that develops primarily from myoepithelial cells. A kallikrein cascade may play a role in the development and/or outcome of some salivary gland tumours.

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.

Background: The salivary gland system of the upper aero digestive tract plays a critical role in the functions of digestion, respiration, communication, and overall homeostasis. The Salivary gland swellings can be broadly classified into inflammatory, non-inflammatory and neoplastic swellings like calculi, benign tumours such has pleomorphic adenoma, oncocytoma, Warthin's tumour, malignant tumors which include-adenocarcinoma, adenoid cystic carcinoma, undifferentiated carcinoma.Methods: The present cross-sectional study was conducted at the Department of general surgery, Sri Siddhartha Medical College over a period of 2 years from August 2016 to July 2018.  All major salivary gland neoplastic swellings confirmed by FNAC were included in this study.Results: In our study 23 patients had major salivary gland tumours out of that 19 patients had parotid and 4 had submandibular major salivary gland tumour. In our study out 23 cases of salivary tumours 19 cases were benign and 4 cases were malignant, out of 19 cases of parotid tumours, 15 (78.94%) cases were seen in superficial lobe and 4 (21.06%) were in deep lobe, out of 23 salivary gland tumours, 19 (82.6%) cases were pleomorphic adenoma 3(13.05%) cases were mucoepidermoid carcinoma and one case (4.35%) was acinic cell carcinoma.Conclusions: Parotid gland was the most common site of origin of both benign and malignant tumours, Pleomorphic adenoma was the most common benign salivary gland tumour and mucoepidermoid carcinoma was the most frequent malignant neoplasm.

Background: Pleomorphic Adenoma is the most common salivary gland tumour accounts 40-70% of all salivary gland tumour and about 60-80% of the benign tumours and 60- 70% of all parotid tumours. There is no study conducted in Bangladesh to observe the clinical and histological variation of the tumour. This study presents 36 cases of Pleomorphic adenoma collected over 11 months at the different territory hospital of Dhaka city. Design: Observational study (November’ 2011 to September’ 2012) Setting: Department of Oral and Maxillofacial Surgery (Dhaka Dental College and Hospital, Bangabandhu Sheikh Mujib Medical Universityl), Department of ENT and Head- Neck Surgery (Dhaka Medical College and Hospital, Bangabandhu Sheikh Mujib Medical University). Method: The entire patient clinically and cytologically diagnosed as Pleomorphic adenoma were selected. Data were collected in a summarized data sheet. Then histopathological types of them were analyzed from excisional biopsized tissue. Result: There were 36 patients of Pleomorphic adenoma of which 24(66.67%) in Parotid glands, 4(11.11%) in Submandibular glands and 8(22.22%) in minor salivary glands. Among the respondents, female was predominant 20(55.56%) with ages were between 29 years to 65 years old (mean age 44.83 ± 8.32 years) with most patients (44.44%) in 41 to 50 years of life. In histophathological study showed Stromal rich 38.89%, cell rich 36.11% and classic 25%. Cuboidal cells were the most commonly found cellular type followed by plasmacytoid and spindle.Trabeculae and duct like structures were the most frequent pattern by the epithelial cells.Myxoid and Hyalinization were the most frequently found mesenchymal like tissue.Cases presented with symptoms such as swelling (100%), limitation of mouth opening, paesthesia and pain. Conclusion: The knowledge about clinical presentation and the immense variety of cells, architectures and morphological characteristics present in Pleomorphic adenoma of the salivary gland is essential for correct diagnosis and prognosis. The need for improved diagnostic facilities and upgrading of infrastructure was stressed. J Bangladesh Coll Phys Surg 2019; 37(2): 72-77

Abstract Basal cell adenocarcinoma is an unusual basaloid tumour that usually affects the parotid and very rarely involves the submandibular or minor salivary glands. It constitutes 1.6% of all salivary gland tumours and occurs as an asymptomatic freely mobile mass with occasional lymph node metastasis. Differentiation from benign salivary gland tumours like basal cell adenoma is accomplished by determining the depth of tumour invasion and patterns of growth or infiltration. Although it is categorised as a low-grade malignancy, it has a high propensity for recurrence. Surgical excision with a wide margin is the preferred course of treatment with radiotherapy being reserved only for tumours of the minor salivary glands with a diffuse pattern of infiltration. We present here a case of basal cell adenocarcinoma with a rare presentation in the minor salivary glands of the tongue which arose from a previously treated basal cell adenoma in the same site.

Mucoepidermoid carcinoma is the most common malignant, locally invasive tumour of the salivary glands and accounts for approximately 35% of all malignancies of the major and minor salivary glands. Mucoepidermoid carcinoma that originated from the lacrimal gland is exceedingly rare in teenage patients, with only a few cases reported. Herein, we report clinical and radiological findings of a mucoepidermoid carcinoma arising from the lacrimal gland in a 15-year-old boy. We suggest that since preoperative imaging findings are not diagnostic for mucoepidermoid carcinoma, histopathologic examination should be performed for definitive diagnosis. Complete surgical resection is the treatment of choice for low-grade lacrimal gland mucoepidermoid carcinoma.
