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 …

A borderline phyllodes tumor is an uncommon breast tumor that arises from the stroma (supportive connective tissue) within the breast. It has characteristics that fall between benign (non-cancerous) and malignant (cancerous) phyllodes tumors. Borderline phyllodes tumors grow faster and have a greater likelihood of recurrence than benign tumors, but they typically do not spread to …

Myoepithelial cells are specialized cells that have features of both muscle cells and epithelial cells. Their primary role is to help push secretions out of glands. They do this by gently contracting, similar to muscle cells, while also forming part of the gland structure, like epithelial cells. These cells are essential to many normal glands …

What is a fibrothecoma? A fibrothecoma is an uncommon and noncancerous type of ovarian tumour made up of thecal cells and fibroblastic spindle cells. It shares features with two other types of noncancerous ovarian tumours, thecomas and fibromas. Is a fibrothecoma benign or malignant? Fibrothecoma is a benign (noncancerous) type of ovarian tumour. What is …

What is a thecoma? A thecoma is an uncommon and noncancerous type of ovarian tumour. The tumour is made up of specialized thecal cells that are normally found in the ovary. Is a thecoma benign or malignant? Thecoma is a benign (noncancerous) type of ovarian tumour. What are the symptoms of a thecoma? The most …

Secretory carcinoma is a type of cancer that starts in the salivary glands — the glands that make saliva. It is one of the more recently described salivary gland cancers, and it has a few features that set it apart. First, it almost always carries the same specific change in its DNA — a fusion …

What is a myoepithelioma? A myoepithelioma is a non-cancerous type of soft tissue tumour. It made up of specialized myoepithelial cells that arise from cells within soft tissue such as muscle, cartilage, or connective tissue. This tumour should not be confused with the similarly named myoepithelioma that starts in the salivary glands. Where is myoepithelioma …

A myoepithelioma is a non-cancerous type of salivary gland tumour. It is made up of specialized myoepithelial cells that are normally found in the salivary gland. This tumour should not be confused with the similarly named myoepithelioma that starts in soft tissue. Is myoepithelioma a type of cancer? No. Myoepithelioma is a benign (non-cancerous) type …

What is a foveolar type adenoma of the stomach? A foveolar type adenoma is a non-cancerous growth that starts from cells on the inside surface of the stomach. It is a rare type of polyp in the stomach although it is slightly more common in people with familial adenomatous polyposis (FAP) syndrome and gastric adenocarcinoma …

An intestinal type adenoma is a non-cancerous growth that starts from the inner lining of the stomach. It is called an “adenoma” because it is made up of abnormal gland-forming cells. These adenomas are considered precancerous, which means they have the potential to turn into cancer over time. Intestinal type adenoma is the third most …
