Synovial sarcoma is a rare type of soft tissue cancer. Despite its name, it does not usually start from the lining of joints (synovium). Instead, it arises from primitive connective tissue cells that exhibit features of both spindle-shaped cells and epithelial cells. This article explains the pathology report for synovial sarcoma, including how it is …

What is sinonasal undifferentiated carcinoma? Sinonasal undifferentiated carcinoma (SNUC) is a type of cancer that starts from cells normally found on the inside of the nasal cavity and paranasal sinuses. This area of the body is called the sinonasal tract. Sinonasal undifferentiated carcinoma is an aggressive disease with a poor prognosis. Can sinonasal undifferentiated sinonasal carcinoma …

Sebaceous carcinoma is an uncommon type of skin cancer. It develops from sebocytes, the cells that make up the oil (sebaceous) glands of the skin. These cells normally produce a fatty substance called sebum, and because the tumor cells continue to make this oily material, the tumor often looks yellow. Sebaceous carcinoma is found most …

Mucoepidermoid carcinoma is a type of cancer that starts in the salivary glands — the glands that make saliva. It is the most common salivary gland cancer in both adults and children. Mucoepidermoid carcinoma can also start in less common locations, including the lungs, the lining of the sinuses, and other glands of the head …

Chordoma is a type of bone cancer. It develops from remnants of an embryonic structure called the notochord. Chordomas almost always develop within a bone and most develop along the midline of the body in either the base of the skull or the sacrum. Chordomas are very slow-growing tumours and can reach a very large …

Intrahepatic cholangiocarcinoma is a type of cancer that starts in the small bile ducts located within the liver. Bile ducts are the tubes that carry bile, a fluid that helps digest fats, from the liver to the intestine. Intrahepatic cholangiocarcinoma is distinct from hepatocellular carcinoma, which starts from the liver cells themselves, and from extrahepatic …
