Spindle cell squamous cell carcinoma is a rare type of squamous cell carcinoma of the larynx (voice box). You may also see it called sarcomatoid squamous cell carcinoma. It is named for the shape of its cells: instead of the rounded cells seen in ordinary squamous cell carcinoma, the cancer cells are long and thin, …

Squamous cell carcinoma is the most common type of cancer of the larynx, also known as the voice box. The larynx sits in the neck and is essential for breathing, swallowing, and speaking. It starts in squamous cells, the flat cells that line the inner surface of the larynx. The larynx is divided into three …

What is a duodenal adenoma? A duodenal adenoma is a non-cancerous type of polyp that starts in a part of the small intestine called the duodenum. It is considered a precancerous condition because it can turn into a type of cancer called adenocarcinoma over time. Another name for this type of polyp is non-ampullary adenoma. …

In pathology, vascular invasion (or angioinvasion) refers to the presence of cancer cells within the blood vessels, including veins and arteries. This finding is significant because it indicates a higher potential for the cancer to metastasize (spread) to other parts of the body, which can occur through any of these vessel types. Why is vascular …

Angioinvasion describes cancer cells that have entered and are present inside blood vessels. Also called vascular invasion, it is significant because blood vessels provide a direct route for cancer cells to travel from the original tumor to distant organs such as the liver, lungs, bones, or brain — a process called metastasis. Finding angioinvasion in …

What is a well differentiated neuroendocrine tumour? A well differentiated neuroendocrine tumour (NET) is a type of cancer made up of specialized neuroendocrine cells. The tumour is described as “well differentiated” because the cells in the tumour look very similar to normal, healthy neuroendocrine cells. These tumours can be found almost anywhere in the body. …

A poorly differentiated neuroendocrine carcinoma is a type of cancer made up of specialized cells called neuroendocrine cells. Neuroendocrine cells normally produce hormones and are found throughout the body, including the lungs, digestive tract, and many other organs. The term “poorly differentiated” means the cancer cells look very abnormal compared to healthy neuroendocrine cells. Because …

Neuroendocrine carcinoma (NEC) is a type of cancer composed of cells that exhibit features of both nerve cells and hormone-producing cells, also known as neuroendocrine cells. These cancers are considered high-grade tumours, which means they tend to grow quickly and may spread to other parts of the body. Neuroendocrine carcinomas can start in many different …

A neuroendocrine tumor (NET) is a type of cancer that starts from neuroendocrine cells. These are specialized cells with features of both nerve cells and hormone-producing cells that help regulate important body functions by releasing hormones in response to signals from the nervous system. Neuroendocrine cells are found throughout the body, which means neuroendocrine tumors …

In a pathology report, the term nuclear atypia is used to describe cells that have abnormal-looking nuclei when examined under a microscope. The nucleus is the part of the cell that contains its genetic material (DNA) and controls how the cell functions. Pathologists use the word “atypia” to mean that something looks unusual or different …
