Spindle cell/sclerosing rhabdomyosarcoma is a rare type of cancer that starts in skeletal muscle tissue, which is responsible for voluntary movements. It can affect people of all ages, but the features of this cancer can vary between children and adults. This type of rhabdomyosarcoma is named for the unique appearance of its cells under the …

Pleomorphic rhabdomyosarcoma is a rare type of cancer that starts in the skeletal muscle tissue, the muscle responsible for voluntary movements like walking or lifting objects. This cancer is called “pleomorphic” because the tumour cells can take on many different shapes and sizes. It is most commonly found in adults, especially in the arms, legs, …

The FNCLCC (Fédération Nationale des Centres de Lutte Contre le Cancer) is the most common grading system doctors use to evaluate soft tissue sarcomas, which are cancers that start in tissues like muscles, fat, or blood vessels. This grading system helps doctors assess how aggressive (fast-growing) the tumour is, guiding treatment decisions and helping predict …

Background: Pleomorphic liposarcoma is a rare and aggressive type of cancer that develops from fat cells. Unlike well differentiated liposarcoma, which still resembles normal fat tissue, pleomorphic liposarcoma is made up of very abnormal cells that look nothing like normal fat cells. This type of cancer can grow quickly and has a higher risk of …

In pathology, the term “rhabdoid” is used to describe tumour cells that resemble rhabdomyoblasts, which are immature skeletal muscle cells. However, these cells are not true rhabdomyoblasts and the tumours they arise in are not related to muscle tissue. Rhabdoid cells can be seen in a wide variety of tumour types and the presence of …

Low grade fibromyxoid sarcoma (also known as Evan’s tumour) is a rare type of soft tissue cancer. As its name suggests, low grade fibromyxoid sarcoma is typically considered a low grade sarcoma, meaning it tends to grow and spread more slowly compared to high grade tumours. However, it has a potential for late recurrence and …

Background: Alveolar soft part sarcoma is a rare type of cancer that typically starts in the body’s soft tissues, including muscles, fat, and connective tissues. Despite its name, alveolar soft part sarcoma does not start in the lung’s alveolar structures, as one might think from the word “alveolar.” Instead, it gets its name from the …

Background: Epithelioid sarcoma is a type of soft tissue cancer. It is called epithelioid because the tumour cells look and behave like epithelial cells that are normally found on the outside or inside surface of any organ. Although epithelioid sarcoma can occur almost anywhere in the body, the most common location is the hand. What …

What is myxofibrosarcoma? Myxofibrosarcoma is a type of cancer that starts in connective tissue. It is one of the most common types of sarcomas to affect older adults. What type of cancer is myxofibrosarcoma? Myxofibrosarcoma is a type of sarcoma. Sarcomas are malignant (cancerous) tumours that start in connective tissue, muscle, or bone. What are …

Dedifferentiated chondrosarcoma is an aggressive type of cancer made up of tumour cells that resemble cartilage. The tumour is called ‘dedifferentiated’ because it develops from within a more well-differentiated type of cartilage cancer called conventional chondrosarcoma. What are the symptoms of dedifferentiated chondrosarcoma? Symptoms of dedifferentiated chondrosarcoma include pain and swelling over the involved bone. …
