High grade salivary gland malignancy Histology is similar to invasive ductal carcinoma of the breast (specifically luminal androgen receptor [AR]+ subtype) In situ areas frequently have comedo necrosis Nearly all cases (> 90%) are AR positiv
A variety of neoplastic and nonneoplastic lesions of the salivary glands have a predominantly cystic architecture. Fine-needle aspirates of these lesions yield watery or mucoid material, frequently of low cellularity The majority of high grade neuroendocrine carcinomas located in the parotid gland represent metastases, usually from the head and neck skin, rather than primary salivary carcinomas. Correlation with clinical history and physical exam findings is recommended to exclude a metastasis Salivary Gland Tumors • Benign • Malignant Relative proportion of malignancy increasing in the smaller glands (rule of thumb is the 25/50/75 rule) 13 14.

The Normal Salivary Gland The system is comprised of major & minor salivary glands Major: Parotid, submandibular & sublingual
SPA is a rare sclerosing tumor of the salivary glands characterized by the combination of cystic ductal structures with variable cell lining including vacuolated, apocrine, mucinous, squamous, and foamy cells, by prominent large acinar cells with coarse eosinophilic cytoplasmic zymogen-like granules, and by closely packed ductal structures, surrounded by a peripheral myoepithelial layer and stromal fibrosis with focal inflammatory infiltrates A sialocele or salivary gland cyst is a fluid filled cavity formed by the disruption of normal salivary flow into the oral cavity. Trauma to the salivary system can disrupt normal flow causing saliva to pool in a major salivary gland or surrounding tissues Fifty-seven of 469 major salivary glands excised for various reasons were found to contain granulomas. The aetiologies were tuberculosis (eight parotid, one sublingual), sarcoidosis (two parotid), calculous duct obstruction (34 submandibular), carcinomatous duct obstruction (four submandibular, one The study of salivary glands may sometimes be complex, because of the number of pathological conditions that may affect them, often with overlapping clinical pictures. Integration of different imaging techniques is often required in the case of swelling of salivary glands, even though biopsy remains the gold standard for a definite diagnosis of.

Most tumours in this gland are benign. Submandibular: Serous and mucinous glands. Serous ~90% of gland. Mucinous ~10% of gland. Serous demilunes = mucinous gland with cap consisting of a serous glandular component The major salivary glands are often irradiated during radiation therapy of head and neck neoplasms. A major adverse effect of such treatment is xerostomia caused by functional and structural impairment of salivary parenchyma (, 11 115). Loss of salivary gland function significantly diminishes the patient's quality of life (, 116) Monomorphic adenomas are benign salivary gland tumors that have a predilection for development in the upper lip and parotid gland. Typically, patients are older persons (mean age, 61 years), but a broad age range (32 to 87 years) has been reported in the literature
The Stafne defect (also termed Stafne's idiopathic bone cavity, Stafne bone cavity, Stafne bone cyst (misnomer), lingual mandibular salivary gland depression, lingual mandibular cortical defect, latent bone cyst, or static bone cyst) is a depression of the mandible, most commonly located on the lingual surface (the side nearest the tongue).The Stafne defect is thought to be a normal anatomical. Atypical pleomorphic adenomas show features such as anaplasia, atypical mitosis, coagulative tumor necrosis and zones of acellular hyalinization. These features might portend malignant transformation. Pleomorphic adenomas with atypical features should be sampled extensively to rule out the possibility of malignancy. slide 42 of 110. Follow us
ion allows for recognition of a new salivary tumor type, in addition to representing a potential diagnostic tool. We sought to characterize a distinctive salivary gland adenocarcinoma that would previously have been regarded as adenocarcinoma NOS. On the basis of the recognition of 5 morphologically identical, distinct low-grade salivary adenocarcinomas, we used targeted RNA sequencing (RNA.

Further details can be found in the original Atlas (Ref 1 ) Summary provided by Dr. Marc Pusztaszeri and reviewed b Sialosis (sialadenosis) is a chronic, bilateral, diffuse, non-inflammatory, non-neoplastic swelling of the major salivary glands that primarily affects the parotid glands, but occasionally involves the submandibular glands and rarely the minor salivary glands (Scully 2008). This can be painless or in some instances tender
• Parotid gland is the largest salivary gland • It has the highest incidence of pathology among the major salivary glands - Benign processes far outweigh malignant processes in terms of incidence • Imaging is useful in: - Determining the morphology of parotid lesions and potential etiologies - Surgical planning for resectio The sections show submandibular salivary gland with a mild patchy mixed mononuclear cell infiltrate, fibrosis and a large benign calcification. No zonal necrosis is identified. Significant nuclear atypia is not identified. Alternate. The sections show a salivary gland with a patchy mixed mononuclear cell infiltrate and fibrosis Abstract. The microscopic findings in 125 cases of mucous retention cyst are presented. Three morphologic patterns are described. In thirty-one cases it was possible to establish a direct continuity between a minor salivary gland duct and the cyst. In an additional twenty-two cases a definitive partial or complete epithelial lining was noted Tuberculous and non-tuberculous (atypical) mycobacterial involvement of the salivary glands may occur.. Primary tuberculous infection of the salivary glands is uncommon and most often consists of unilateral parotid gland involvement. The infection is thought to arise in the teeth or tonsils and may result in acute inflammation or a chronic tumorlike lesion
Uninvolved salivary gland can be seen on the lower right of the specimen. Microscopically, it was a high-grade mucoepidermoid carcinoma. Case courtesy of: Dr. Sanjay D. Deshmukh, Dept. of Pathology, Smt. Kashibai Navale Medical College, Pune, India Bartholin cyst - the most common cyst of vulva - it is cystic dilatation of Bartholin gland or its duct. The glands are located behind labia minora and drain into postero-lateral vestibule. Blockage of the duct, perhaps secondary to infection, can lead to retained secretions and cyst formation. The low-power view shows the dilated duct lined by. Incisional biopsy of minor salivary glands was introduced as a clinical diagnostic procedure for Sjogren's syndrome in 1966. Many studies since that time have examined the value of this biopsy procedure (Marx, Hartman, and Rethman 1988).

Often duct hyperplasia occurs in a salivary gland that has undergone tissue damage and appears to be a regenerative process ( Figure 5 and Figure 6). It is a common feature of many inflammatory and reactive conditions in the salivary glands of rodents, dogs, monkeys, and humans and can be associated with the presence of stones and calculi. malignancy of the salivary gland (about half as frequent as mucoepidermoid carcinoma) •80% arise in the parotid gland Gary L. Ellis and Paul L. Auclair. Tumors of the Salivary Glands. AFIP Atlas of Tumor Pathology. Series 4. 2008 Inflammatory conditions are the most common pathology affecting the salivary glands. Due to routine immunization, the incidence of mumps has declined and sialolithiasis is the most frequent salivary gland pathology in most of the developed world; 80% of cases involve the submandibular gland.1-3. Salivary gland tumors account for 2% to 3% of all. Salivary gland tumors (SGTs) are rare neoplasms accounting for 0.4-13.5 cases per 100000 people. Malignant SGTs represent 6% of head and neck cancers and 0.3% of all cancers in the US. Still in the US, carcinomas of the major salivary glands comprise 11% of oropharyngeal neoplasms
The sections show a cystic tumour with lymphoid tissue associated with benign salivary gland tissue. The lymphoid tissue is composed of small cells and forms morphologically unremarkable follicles. The cyst-lining epithelium has a bilayered appearance and is composed of cells with abundant eosinophilic cytoplasm and nucleoli This short time and a relatively low incidence, estimated at less than 2% of all salivary gland tumours, have not allowed histopathologic review of any sizable number of the tumours. The present study of 102 monomorphic adenomas; 96 in major salivary glands, establishes the histologic heterogeneity of the tumours and permits a classification. 9.1 General Introduction. In the head and neck region, there are up to 750 minor salivary glands. 1 Minor salivary gland tumors represent a small subset (15-20%) of all salivary gland tumors, which in turn comprise only 3 to 5% of cumulative head and neck tumors. 2, 3 The most common site of minor salivary gland tumors is the oral cavity. Unlike in major salivary glands, tumors of the minor. Introduction. The histopathology of the salivary glands is a complex and difficult area of diagnostic pathology. In the latest World Health Organization (WHO) classification 1 there are 40 named neoplasms, many of which have variable histological features that can challenge even the most experienced specialist pathologist. In addition, the salivary glands can be affected by a range of non.

Mucinous Adenocarcinoma of Salivary Gland is a rare type of malignant epithelial tumor affecting either the major or minor salivary glands. It is mostly observed in adults. The cause of formation of this salivary gland malignancy is generally unknown, but may be due to genetic factors Salivary glands are made up of secretory acini (acini - means a rounded secretory unit) and ducts. There are two types of secretions - serous and mucous.The acini can either be serous, mucous, or a mixture of serous and mucous.. A serous acinus secretes proteins in an isotonic watery fluid. A mucous acinuss secretes secretes mucin - lubricant. In a mixed serous-mucous acinus, the serous acinus. salivary gland sites: parotid (40%), minor glands.
