AbstractThe ultrastructural, X-ray microanalytical, histochemical and immunocytochemi-cal features of intraluminal crystalloids found in adenocarcinomas of the parotid gland have been studied. The crystalloids, putatively derived from an abnormal crystalization of salivary duct proteins, are considerably different from the crystalloids found in normal parotid glands, pleomorphic adenomas, and sialocysts.

AbstractAn oncocytic mucoepidermoid carcinoma and an oncocytic pleomorphic adenoma occurred in a 47-year-old male and a 75-year-old female, respectively. Both presented as asymptomatic parotid gland masses without evidence of facial nerve paralysis and were treated by superficial parotidectomy. There has been no evidence of recurrence or metastasis. Oncocytic change is rare in major salivary gland mucoepidermoid carcinoma with only two previously reported cases. Marked oncocytic transformation of pleomorphic adenomas can cause their confusion with oncocytomas. Recognition of oncocytic differentiation in various salivary gland tumours is important to avoid misclassification of these lesions.

Introduction: Salivary gland tumours account for 3-6% of tumours of the head and neck. About 80% of salivary gland tumors occur in parotid glands, 10-17% of which are malignant The aim of the study was to assess whether there is an upward trend in cancer incidence within the parotid glands, with particular emphasis on cancers. Materials and methods: 322 patients underwent surgery and 328 parotid gland tumours were removed in the years 2005-2014 at the Department of Laryngology and Laryngological Oncology of the Upper Silesian Medical Centre in Katowice-Ochojec. Clinical, histopathological and statistical analyses of the removed parotid gland tumours were performed. Results and discussion: A significant increase in the incidence of benign tumours, especially mixed and Warthin tumours, was demonstrated. There was no significant increase in the number of malignant tumours over the analysed period of time.

Key Aspects

Salivary gland tumours are uncommon and account for just 6% of all head and neck neoplasms. Worldwide incidence varies, from 0.4 to 13.5 cases per 100 000 population. The parotid gland is by far the most commonly affected site, accounting for 80% of cases. The vast majority of these tumours are benign; only approximately 20–25% being malignant. This article considers the relevant clinical anatomy of the parotid gland, key aspects of assessment with history and examination, and when to refer to secondary care for further investigation. It will touch on the common benign and malignant parotid neoplasms and give an overview of secondary care management.

Rare Lesion

Minor salivary gland tumours are enigmatic in their behaviour and presentations. Histopathological diagnosis of these tumours encompasses a large spectrum. Conventionally, small nodular tumours of the upper lip or the labial mucosa are generally adenomas, frequently pleomorphic adenomas. Here, we describe a case of a solitary nodular tumour, occurring in the upper labial mucosa, diagnosed as sclerosing polycystic adenoma (SPA) with intraductal epithelial proliferation of high grade. This is a rare lesion, which has entered into the category of salivary gland tumours recently in the 2017 WHO categorisation. We report a case of paucicystic SPA with intraductal epithelial proliferations in the labial minor salivary gland of a 56-year-old woman, which might be the first report of a case occurring in the upper labial mucosa.

Salivary gland tumours make an important part of oral & maxillofacial pathology. Only few studies have been done in Pakistani population. The aim of this study was to describe morphological types of salivary gland tumours diagnosed at King Edward Medical College/ Mayo Hospital, Lahore during the years 1999-2001 and to compare their demographic data with those previously published. Material & Methods: This descriptive cross-sectional study was carried out at King Edward Medical College/ Mayo Hospital, Lahore. It reports 117 cases of salivary gland tumours diagnosed at Pathology Department during 1999-2001. Results: Of the 128 specimens of salivary glands, 117(91.4%) were confirmed as salivary neoplasms. Out of them, 62.7% were benign and 37.6% malignant and a slight female predominance (58.1%) was found. The most common location was the parotid gland (65.8%) followed by minor salivary glands (19.6%). Majority oft he t tumours was diagnosed during 3rd to 5 decades of life. Median age for benign tumours was 33 years (range 1-78) and a female predominance (58.9%) was seen again. Median age for malignant neoplasms was 45 years (range 9-70) with a female predilection ( 56.8%). However, 4 out o f 5 patients with Warthin`s tumour were men. Pleomorphic adenoma was the most frequent tumour (51.3%), followed by mucoepidermoid carcinoma (25.6%), adenoid cystic carcinoma (7.7)), Warthin`s tumour (4.3%) and monomorphic adenoma (2.6%). Two cases each of oncytoma & adenocarcinoma were recorded. Rare categories (single case each) of salivary tumours included lipoma, acinic cell carcinoma, basal cell adenoma, capillary haemangioma, metastatic carcinoma and non Hodgkin`s lymphoma. Conclusion: The principal site of salivary tumours was the parotid gland and females were most affected. Pleomorphic adenoma was the most frequent finding. The results of this study are comparable with other studies.

AbstractThe synchronous or metachronous occurrence of two tumours of the salivary glands in one patient is rare. These are mainly benign and of the same histological type. Here we report a 56-year-old man who developed a mucoepidermoid tumour of the left parotid gland four years after diagnosis of adenoid cystic carcinoma of the right submandibular gland. This combination of neoplasms has not to our knowledge been reported before.

Salivary Gland Malignancy

We report a rare case of bilateral basal cell adenocarcinoma (BcAC) of the parotid gland in a male patient 30 years after kidney transplantation and continuous administration of immunosuppressive therapy. BcAC is a salivary gland malignancy first recognized as a distinct neoplastic entity in WHO classification of salivary gland tumours in 1991. Over 90% of BcACs are detected in the parotid gland. The most important differential diagnosis is basal cell adenoma. Infiltrative growth is the distinguishing feature of BcAC. Administration of immunosuppressive medication to this patient for three decades may have contributed to development of this rare neoplasia. To our knowledge, similar cases of BcAC have not been reported previously.

Salivary gland tumours most often present as painless enlarging masses. Most are located in the parotid glands and most are benign. The principal hurdle in their management lies in the difficulty in distinguishing benign from malignant tumours. Investigations such as fine needle aspiration cytology and MRI scans provide some useful information, but most cases will require surgical excision as a means of coming to a definitive diagnosis. Benign tumours and early low-grade malignancies can be adequately treated with surgery alone, while more advanced and high-grade tumours with regional lymph node metastasis will require postoperative radiotherapy. The role of chemotherapy remains largely palliative. This paper highlights some of the more important aspects in the management of salivary gland tumours.

AbstractPleomorphic adenomas arising from sites other than the major or minor salivary glands are uncommon. We describe a case of pleomorphic adenoma in the subcutaneous tissue of the nasomaxillary crease. An identical tumour was previously excised from the right nasal cavity. The possible aetiology of these heterotopic salivary gland tumours is discussed.
