Salivary gland neoplasm of uncertain malignant potential (SUMP) is a descriptive diagnosis used by pathologists when a tumor is found in a salivary gland but there is not enough information to determine whether it is benign (noncancerous) or malignant (cancerous). It does not refer to a single disease but rather to a range of possible …

Striated duct adenoma is a rare, benign tumour that develops in the salivary glands, most often in the parotid gland, situated in front of and below the ears. The tumour is made up of small ducts (tiny tube-like structures) similar to those normally found in the salivary glands. These tumours are typically slow-growing and do …

IgG4-related sialadenitis is a chronic inflammatory condition that affects the salivary glands, which produce saliva in your mouth. It is part of a group of IgG4-related diseases (IgG4-RD). In this condition, the immune system produces too much of an antibody called IgG4, leading to inflammation and swelling of the salivary glands. The inflammation can cause the …

Basal cell adenocarcinoma is a rare type of cancer that starts in the salivary glands, which are responsible for producing saliva in the mouth and throat. It is called “basal cell” because the tumour is made up of cells that resemble the basal cells normally found in salivary gland tissue. Basal cell adenocarcinoma is usually …

Epithelial-myoepithelial carcinoma (EMC) is a type of salivary gland cancer. The tumour is described as a biphasic salivary gland neoplasm because it comprises two populations of cells: ductal (luminal) and myoepithelial (abluminal) cells. The most common location for epithelial-myoepithelial carcinoma is the parotid gland. However, the tumour can be found in any salivary glands, including …

Carcinoma ex pleomorphic adenoma is a type of salivary gland cancer that develops from within a previously benign (noncancerous) tumour called pleomorphic adenoma. In pathology, carcinoma is a general term used to describe a group of malignant (cancerous) tumours made up of epithelial cells, while “ex” means “out of” or “from”. Put together, carcinoma ex …

A myoepithelioma is a non-cancerous type of salivary gland tumour. It is made up of specialized myoepithelial cells that are normally found in the salivary gland. This tumour should not be confused with the similarly named myoepithelioma that starts in soft tissue. Is myoepithelioma a type of cancer? No. Myoepithelioma is a benign (non-cancerous) type …

Warthin tumour is a noncancerous tumour that most often develops in the parotid gland, the largest salivary gland located near the jaw and in front of the ear. It is the second most common type of salivary gland tumour, after pleomorphic adenoma. Warthin tumour is sometimes referred to by older terms, such as papillary cystadenoma lymphomatosum …
