Salivary gland tumors
Salivary gland tumors are variable in location, origin, and malignant potential.
Pathology

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
The parotid gland is the largest of the paired major salivary glands, located in the parotid space. It secretes predominantly serous saliva via the parotid duct into the oral cavity to facilitate mastication and swallowing. During meals and mastication, the parotid gland is responsible for most ...

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...

Sialosis
Sialosis or sialadenosis (plurals: sialoses or sialadenoses) refers to diffuse, non-inflammatory, non-neoplastic recurrent/persistent enlargement of the major salivary glands, caused by hypertrophy of the acinar components. Typically, the parotid gland is most affected, although submandibular gl...

Salivary glands
The salivary glands within the head and neck secrete various enzymes useful for mastication and digestion. They can be divided into major and minor salivary glands.
Major salivary glands
The major salivary glands consist of the larger, paired salivary glands within the neck:
parotid glands

Heterotopic salivary gland tissue

It is also often referred to as salivary gland choristoma or ectopic salivary gland 1. In heterotop...
