Location: It is located in the anterior part of digastric triangle partly deep in the submandibular fossa of mandible and partly below the mandible Submandibular Tumors. Major salivary glands contain several different groups of functioning and support cells. This leads to the variety of possible histologic diagnoses discussed in Chapter 22.Precise histologic diagnosis by frozen section and needle biopsy may be difficult, especially with regard to distinguishing between benign and malignant neoplasms
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 accessory glands mostly malignant.

The submandibular gland is supplied by postganglionic parasympathetic, secretomotor fibers derived from the submandibular ganglion (see fig. 49-3).
