Benign lymphoepithelial lesions
Benign lymphoepithelial lesions (BLL or BLEL), also misleadingly known as AIDS-related parotid cysts (ARPC), are mixed solid and cystic lesions that enlarge the parotid glands, and are usually associated with cervical lymph node enlargement, and nasopharyngeal lymphofollicular hyperplasia.

Pleomorphic adenoma of the salivary glands
Pleomorphic adenomas of the salivary glands, also known as benign mixed tumors (see below), are the most common salivary gland tumors. The salivary glands are the most common site of pleomorphic adenomas.
On imaging, they commonly present as well-circumscribed rounded masses, most commonly loca...

Salivary gland tumors
Salivary gland tumors are variable in location, origin, and malignant potential.
Pathology
In general, the ratio of benign to malignant tumors is proportional to the gland size; i.e. the parotid gland tends to have benign neoplasms, the submandibular gland 50:50, and the sublingual glands and...

Warthin tumor
Warthin tumors, also known as lymphomatous papillary cystadenomas, are benign, sharply demarcated salivary gland tumors, almost exclusively encountered in the parotid gland. They are of lymphoid origin and may be bilateral or multifocal in up to 20% of cases and are the most common neoplastic ca...

Acinic cell carcinoma (salivary glands)
Acinic cell carcinomas of the salivary glands are rare malignant neoplasms that account for 1-3% of all salivary gland tumors.
Pathology
Pathology may superficially resemble normal serous (acinar) cells of the salivary glands. It is considered a low-grade, indolent malignancy, but with a tend...

Carcinoma ex pleomorphic adenoma
Carcinoma ex pleomorphic adenoma is the most common of three malignant mixed tumors of salivary glands, and are thought to arise from pre-existing pleomorphic adenomas (historically also called benign mixed tumors, but see below) 1,3.
Epidemiology
These tumors usually occur in older patients (...

Malignant mixed tumors of salivary glands, according to the WHO classification, comprise three tumors:
carcinoma ex pleomorphic adenoma
arises from pre-existing pleomorphic adenoma

true malignant mixed tumor
99% also aris...

Major salivary gland cancer (staging)
Major salivary gland cancer staging refers to TNM staging of malignant tumors of the major salivary glands (parotid, submandibular, and sublingual glands). In contrast, tumors arising from minor salivary glands are staged according to their site of origin. The following article reflects the 8th ...

Parotid gland enlargement
Parotid gland enlargement (also known as parotidomegaly) has a wide differential given the significant breadth of pathology that can affect the parotid gland. These can be separated by a standard surgical sieve approach into infective, inflammatory, immune, neoplastic, infiltrative, and congenit...
