Salivary glands produce saliva to aid in chewing and digesting food. Although the specific cause of this condition is unknown, parotid cysts commonly occur in patients with HIV. The tumor has the following three components: epithelial cell, myoepithelial cell, and stromal/mesenchymal. Among major salivary glands, the most commonly affected site is the parotid gland Minor salivary glands that may be affected include those of oral cavity, sinonasal tract, nasopharynx, oropharynx and trachea Essential features Grows in tubular, cribriform, and/or solid patterns: solid pattern is associated with adverse outcome A possibility of oncocytoma was entertained. Parotitis is inflammation of the parotid gland. The cyst is thick walled and fluid filled, and a secondary follicle lined by dark basophilic granulosa cells is present in the adjacent parenchyma. The lymphoid tissue is composed of small cells and forms morphologically unremarkable follicles. In very unusual circumstances, this type of tumor can become cancerous," Eisele says. The sections show a cystic tumour with lymphoid tissue associated with benign salivary gland tissue. In addition there are about 800-1000 minor salivary glands in the mucosa of the mouth.

Branchial cysts can occur within the lymph nodes in the parotid gland and on the surface of the gland [ 10 ]. The benign lymphoepithelial lesions (BLLs) of major salivary glands, particularly of parotid glands, are rare disorders affecting HIV-infected patients and are also associated with Sjgren syndrome. Minor glands are involved in 9-23% of SGT cases. Lobular neoplasia can coexist with columnar cell lesions, flat epithelial atypia, atypical ductal hyperplasia, and low-grade invasive carcinoma , referred to as the "low nuclear grade neoplasia family" of breast lesions (Figs. keratocystoma of the parotid gland was first defined and reported as an unusual pathological entity in 2002. Micro The sections show a multiloculated cyst with thin walls containing bland lymphoid cells and unremarkable paucicellular fibrotic tissue. papilla; debris; corpora amylacea; calcifications. sialolithiasis; lymphoepithelial cyst. The parotid gland is located in front of each ear, and secretes mostly serous saliva via the parotid duct (Stenson duct) into the mouth, usually opening roughly opposite the maxillary second molar.

The most common minor salivary gland site is the palate. Most SGTs occurring in the sublingual glands are malignant (70-90%). Some, however, may arise from surrounding structures. Definition / general Reactive lesion to salivary gland duct obstruction and buildup of trapped mucin within Essential features Mucus trapped within lumen secondary to salivary gland duct obstruction Severe obstruction can lead to squamous or oncocytic metaplasia of duct epithelial bilayer Ddx . 2 layers. 10.20, 10.21, 10.22, and 10.23). Parotid tumors are abnormal growths of cells (tumors) that form in the parotid glands. The cyst-lining epithelium has a bilayered appearance and is composed of cells with abundant eosinophilic cytoplasm and nucleoli. Benign cysts in the parotid gland have an equal distribution among males and females, and usually present as a uni- lateral painless swelling in the parotid area without attachment to the overlying skin or involvement of the facial nerve1"2'Ia1'22. Lieu et al. reported the first case of BHD with parotid oncocytoma in a 56-year-old man [ 5 ]. John R. Goldblum MD, in Rosai and Ackerman's Surgical Pathology, 2018 Benign Lymphoepithelial Cysts and HIV-Related Lesions. Developmental disorders: heterotopia. They usually arise within the gland from salivary or non-salivary parotid tissue, and may be congenital or acquired. sebaceous adenoma / lymphadenoma sialadenoma papilliferum Warthin tumor Pathology Outlines - Salivary glands select article Molecular advances in salivary gland pathology and their practical application Mini-Symposium: Salivary Gland Pathology - ScienceDirect Page 1/3 Forms in the major salivary glands, also known as the parotid glands.

Overview Benign tumours Tabular form - adapted from Thompson Malignant tumours Tabular form - adapted from Thompson DDx Palate Polymorphous low-grade adenocarcinoma. Between 54 and 79% of all tumors are benign, and 21 to 46% are malignant. The parotid gland is the site most often affected, accounting for 78%-84% of salivary gland oncocytomas [ 12 ]. Cervical signs include pit-like depression near angle of mandible with recurrent watery discharge which can be purulent if infected. There was no pus discharge from or inflammation of the duct orifice. Other neck mass lesions Cystic lesions : Thyroglossal duct cyst, Branchial cleft cyst, Thymic cyst, Metastatic squamous cell carcinoma with cystic change, Metastatic thyroid papillary carcinoma with cystic change 105 Meningioma 111 Carotid body tumor 112 In most of the cases the superficial lobe of the parotid gland is involved [ 19 ]. "There are different types of tumors, but the most common type is pleomorphic adenoma, a slow-growing tumor. The wide variety of tumor etiology, microscopic histology, growth patterns, and tumor characteristics can make diagnosis and treatment challenging for clinicians.
