HPV-associated squamous cell carcinoma is a type of cancer that starts from squamous cells, which are flat cells lining the inside of the nasal cavity and the paranasal sinuses. The nasal cavity is the hollow space inside the nose that helps warm and filter air, while the paranasal sinuses are air-filled spaces in the bones …

Myoepithelial carcinoma is a rare cancer that starts in the salivary glands. It develops from myoepithelial cells, which are specialized cells normally found in the salivary gland. This tumour can arise on its own or from a pre-existing noncancerous tumour called pleomorphic adenoma. Myoepithelial carcinoma is typically a slow-growing type of cancer, but it can …

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 …

What is non-intestinal-type sinonasal adenocarcinoma? Non-intestinal-type sinonasal adenocarcinoma (SNAC) is a rare type of head and neck cancer. The tumour starts from the tissue that lines the inside of the nasal cavity or the paranasal sinuses such as the ethmoid or maxillary sinus. Pathologists divide non-intestinal-type SNAC into two grades, low and high, with high-grade …

Acinic cell carcinoma is a type of cancer that starts in the salivary glands. These are the glands that produce saliva and include the parotid glands (located in front of the ears), submandibular glands (located under the jaw), and sublingual glands (located under the tongue), along with numerous small minor salivary glands distributed throughout the mouth …

Hyalinizing clear cell carcinoma (HCCC) is a slow-growing type of head and neck cancer. A genetic alteration involving the EWSR1 gene is found in most tumours. This type of cancer is typically found in minor salivary glands in the lip, tongue, buccal mucosa (inner cheeks), gingiva (gums), hard and soft palate (the roof of the …

Adenoid cystic carcinoma is a rare type of cancer that grows slowly but can invade deeply into surrounding tissues. It most commonly starts in the major salivary glands such as the parotid, submandibular, or sublingual glands. However, it can also develop in other parts of the body, including the skin, lungs, breasts, and prostate gland. …

Mucoepidermoid carcinoma is a type of salivary gland cancer. The salivary glands are small saliva-producing organs located in the head and neck. Although less common, this type of cancer can also be found in the nasal cavity and lungs. Mucoepidermoid carcinoma comprises three types of cells: mucus-producing cells, epidermoid (squamous-like) cells, and intermediate cells that …
