    Pleomorphic adenoma is the most frequent benign tumour of both the major (extra-oral) and the minor (intra-oral) salivary glands. 80% of the cases occur in the parotid gland (mixed parotid tumour). This tumour occurs most commonly in the fourth to fifth decade, with a prevalence in females. Clinically, there is a slowly growing swelling which may reach a significant size.   Salivary gland neoplasms make up 6% of all head and neck tumors. [] The incidence of salivary gland neoplasms as a whole is approximately cases per , individuals in the United States, with malignant neoplasms accounting for cases per , [] Mortality from malignant salivary gland neoplasms varies by stage and pathology, but the .

Salivary glands may be predominantly serous, mucous, or mixed in secretion. Mucus is a thick, clear, and somewhat slimy substance. Serous secretion is .   SALIVARY GLAND tumors are a comparatively rare disorder, accounting for only 1% of all neoplasms of the head and neck region. 1 Further complicating the analysis of these tumors in the pediatric population is that fewer than 5% of all salivary tumors occur in patients younger than 16 years. 2 Not all masses arising in a salivary gland region represent tumors of Cited by:

THACKRAY, M.D. Bland-Sutton Institute of Pathology, The Middlesex Hospital, London, W. 1 Mucous gland tumours may arise in connection with any of the three main groups of glands--the major salivary glands, the minor salivary glands and the mucous glands of the respiratory by: 1.

About 85% of salivary gland tumors occur in the parotid glands, followed by the submandibular and minor salivary glands, and about 1% occur in the sublingual glands. About 75 to 80% are benign, slow-growing, movable, painless, usually solitary nodules beneath normal skin or mucosa.

Worldwide annual incidence of salivary gland tumours varies from to % per 1 lakh population. 1 Overall about % of head and neck cancers are salivary gland neoplasms. salivary glandtumours A number of biological main features, of importance for the present study, from the recent Scandinavian investigations into mucous and salivary gland tumours will be briefly summed up.

The mucous and salivary gland tumours belong to the com-paratively rare forms. Theyoccur mostoften in the large salivaryCited by: Most salivary gland tumors are benign and occur in the parotid glands. A painless salivary mass is the most common sign and is evaluated by fine-needle aspiration biopsy.

Imaging with CT and MRI can be helpful. For malignant tumors, treatment is with excision and radiation. Long-term results are related to the grade of the cancer. Salivary gland tumours present a diverse range of histological and clinical behaviours. The rarity of these tumours combined with the diverse histology means that there is a lack of studies that can be used to provide strong recommendations for each individual histologic subtype of Cited by: Salivary secretions and structure.

Saliva consists of two fluids, mucous and serous. Mucous. Mucous (slime) is a saccharide glycoprotein called water it makes the slippery lubricant used in many parts of the body, where it lines the moving parts, surfaces and tubes.

Here it lubricates the mouth, throat and alimentary canal. The mucous also has antiseptic. The Lancet LEADING ARTICLES Salivary-gland Tumours SALIVARY-GLAND tumours are relatively uncommon, but they have occasioned much interest and debate because of their great variability in structure and behaviour.

It is only in the past two or three decades, following technical advances in the surgery of the major salivary glands, that. These tumours can be benign or malignant, with parotid tumours less likely to be malignant than those in the submandibular, sublingual or minor salivary glands.

Epidemiology. Salivary gland tumours have an incidence of 1 inThey are slightly more common in women than in men and more common in adults. 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 Cited by: that 26% of minor salivary gland tumours were poly-morphous low grade adenocarcinomas, and in an African population, Van Heerden and Raubenheimer () found it to be the most common intraoral salivaryglandmalignancy.

Approaches to the diagnosis of salivary gland tumours Salivary tumours are a particular challenge to the diagnostic pathologist. 67 Abstract: The aims of this study were to determine the incidence of malignant salivary gland tumors (MSGTs) in a specific in Spanish Mediterranean population, evaluate oncological outcomes, and.

More than 30 percent of salivary gland cancers are thought to be this type. Cancers that develop here often form tiny mucous-filled cysts.

Although almost 40 histologic types of epithelial tumors of the salivary glands exist, some are exceedingly rare and may be the subject of only a few case reports.[1,11] The most common benign major and minor salivary gland tumor is the pleomorphic adenoma, which comprises about 50% of all salivary gland tumors and 65% of parotid gland tumors.

The salivary gland section in the 4th edition of the World Health Organization classification of head and neck tumors features the description and inclusion of several entities, the most significant of which is represented by (mammary analogue) secretory carcinoma.
