Dedifferentiated liposarcoma is an aggressive type of sarcoma — a cancer that arises from fat cells. It is called dedifferentiated because it develops from within a less aggressive fatty tumor called well-differentiated liposarcoma (also known as atypical lipomatous tumor). During this transformation, a portion of the tumor’s fat cells are replaced by a completely different …

Myxoid liposarcoma is a type of cancer that starts in fat cells. It is classified as a sarcoma — a cancer arising from the connective tissues of the body — and more specifically as a type of liposarcoma, meaning a sarcoma of fat tissue. Myxoid liposarcoma most commonly develops in the deep soft tissues of …

What is an intramuscular lipoma? Intramuscular lipomas are non-cancerous tumours made up of fat. These tumours develop deep inside a muscle and they may feel like a lump. Often, intramuscular lipomas are not well separated from the surrounding normal muscle which can make it challenging for your surgeon to remove the tumour completely. What is …

An angiolipoma is a benign (noncancerous) soft tissue tumour that develops in the subcutis, the layer of fat just beneath the skin. It is composed of two main components: mature fat cells, which resemble normal body fat, and small, thin-walled blood vessels, some of which contain tiny clots called fibrin thrombi. These features help pathologists …

What is spindle cell lipoma? A spindle cell lipoma is a non-cancerous tumour made up of fat and long, thin spindle cells. This tumour commonly starts around the upper back and neck but can be found almost anywhere in the body. Most grow just under our skin where they feel like a soft lump. Another …

A lipoma is a benign (non-cancerous) tumour made up of mature fat cells, also called adipocytes. Lipomas are part of a group of tumours known as mesenchymal tumours, which arise from connective tissues such as fat, muscle, or fibrous tissue. Lipoma is the most common type of soft tissue tumour in adults. Lipomas grow slowly …

Adenocarcinoma is the most common type of stomach cancer, accounting for about 90 to 95% of all cases. It starts in the gland-forming cells that line the inside of the stomach — cells that normally produce mucus and digestive juices to protect the stomach and help it break down food. In adenocarcinoma, these cells grow …

Clear cell carcinoma of the ovary is a type of ovarian cancer named for the appearance of its cells under the microscope — many of the tumor cells have large amounts of a substance called glycogen inside them, which washes out during the preparation of the tissue slide and leaves the cell’s interior looking pale, …

Mucinous carcinoma of the ovary is a type of ovarian cancer that develops from cells that produce mucus. Under the microscope, the tumor cells resemble the cells that line parts of the digestive tract, such as the stomach or intestines, which is why pathologists describe this tumor as having “mucinous” or gastrointestinal-type features. Mucinous carcinoma …

Low-grade serous carcinoma of the ovary is a type of ovarian cancer that develops from cells similar to those lining the fallopian tube. It is called “low grade” because the tumor cells look less abnormal under the microscope and tend to grow more slowly than those seen in high-grade serous carcinoma. Low-grade serous carcinoma accounts …
