Perivascular epithelioid cell tumour, also known as PEComa or PEC tumour, is a family of mesenchymal tumours consisting of perivascular epithelioid cells (PECs). These are rare tumours that can occur in any part of the human body. The cell type from which these tumours originate remains unknown.

Adenocarcinoma of Mullerian origin: review of pathogenesis, molecular biology, and emerging treatment paradigms Type II cancers account for approximately 75% of EOC and the vast majority of ovarian cancer deaths. These include high-grade serous and high-grade endometrioid carcinomas, as well as carcinosarcomas and undifferentiated carcinomas. These cancers are typically aggressive and diagnosed at a later stage [13,14,17]. Until recently the origin or precursor lesion for the type II cancers was unknown [18].

- The earliest form of squamous cell cancer is called carcinoma in situ, meaning that the cancer cells are present only in the outer layer of cells called the epithelium. This is different from invasive squamous cell carcinoma, where the cancer cells have grown into deeper layers of the oral cavity or oropharynx.

Cancer Types Breast cancer can be separated into different types based on the way the cancer cells look under the microscope. Most breast cancers are carcinomas, a type of cancer that starts in the cells (epithelial cells) that line organs and tissues like the breast.In fact, breast cancers are often a type of carcinoma called adenocarcinoma, which is carcinoma that starts in glandular tissue.his is the most common type of breast cancer. Invasive (or infiltrating) ductal carcinoma (IDC) starts in a milk duct of the breast, breaks through the wall of the duct, and grows into the fatty tissue of the breast.

- Glandular epithelium is composed of cells that are specialized to produce and secrete substances. Such cells occur most commonly within columnar and cuboidal epithelia, and one or more of these cells constitute a gland.f the duct and secretory portions are of uniform diameter, the gland is tubular. If the secretory cells form a dilated sac at the end of the duct, it is acinar, and if the secretory cells extend uniformly from the duct then form a sac, it is called tubuloacinar.

Top 30 Doctor insights on: Breast Cancer Genes Brca1 And Brca2 How type is determined. Most breast cancers are carcinomas. These cancers start in the cells that line organs and tissues. (These cells are called epithelial cells.) In fact, breast cancers are often a type of carcinoma called adenocarcinoma, which starts in cells that make glands (glandular tissue).

Original Article Among ovarian cancers, clear cell carcinoma is unique for its stroma, as well as its distinct cell type. The most recognized stromal change is hyalinization. The deposition of basement membrane material, including laminin-5 and type IV collagen, is responsible for hyalinization.

Types of cells and cancer Different types of cells in your bodyYour body is made up of billions of cells that can only be seen under a microscope. These cells are grouped together to make up the tissues and organs of our bodies. These cells are basically the same, but they do vary in some ways. This is because the body organs do very different things. For example, nerves and muscles do very different things. So nerve and muscle cells are different.The different types of cells can be grouped together or classified according to the job they do, or the type of body tissue they make up. For example there are: Epithelial tissue cells Connective tissue cells Cells of the blood and lymphatic system Epithelial tissueâEpithelialâ tissue is basically skin tissue that covers and lines the body. As well as covering the outside of the body, epithelial cells cover the inside too. They cover all the body organs, for example the organs of the digestive system and line the body cavities such as the inside of the chest cavity and the abdominal cavity.Most cancers are cancers of the epithelial cells. Cancers of the epithelial cells are called âcarcinomasâ. Carcinomas make up about 85% of all cancers.There are different types of epithelial cells and these can develop into different types of cancer. For example, epithelial cells can beFlat surface covering cells called squamous cells Glandular cells called adenomatous cells Layers of stretchy cells called transitional cells So you can have: Squamous cell carcinoma of squamous cells Adenocarcinoma of glandular cells Transitional cell carcinoma of transitional cells Squamous cells and adenomatous cells are found in all body organs. Cancers are named after the body organ they grow in as well as the type of cell. So a cancer of the squamous epithelial cells covering the lung would be âsquamous cell lung cancerâ.Connective tissueConnective tissue is the name for the supporting tissue of the body, the bones, cartilage, tendons and fibrous tissue that supports the body organs. Connective tissue cancers are called âsarcomasâ. Sarcomas can develop fromBone Cartilage MuscleSarcomas are much less common than carcinomas. They make up about 6% of all cancers.Blood and lymph tissueThere are many different types of blood and lymph tissue cells. These are really specialised connective tissue cells. The blood cells are made in the bone marrow in tissue called haematopoetic tissue. Blood and lymph tissue can develop intoCancers of the blood cells â leukaemias Cancers of the lymphatic system â lymphomas Leukaemias and lymphomas make up about 5% of all types of cancer. But they are the commonest type of cancer affecting children.Other body tissues and cancerOther body tissue cells can become cancerous. But these types of cancer are very rare. The biggest group of these rare cancers are brain tumours. Brain tumours develop from the cells that support the nerve cells in the brain, called glial cells. These cancers also get their names from the cells they developed from. So cancers of the glial cells are called âgliomasâ. Most cancers are cancers of the epithelial cells. Cancers of the epithelial cells are called ‘carcinomas’. Carcinomas make up about 85% of all cancers. There are different types of epithelial cells and these can develop into different types of cancer.ypes of cells and cancer. Different types of cells in your body.

Carcinoma Carcinoma is a type of cancer that develops from epithelial cells. Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that generally arises from cells originating in the endodermal or ectodermal germ layer during embryogenesis.he term carcinoma has also come to encompass malignant tumors composed of transformed cells whose origin or developmental lineage is unknown (see cancer of unknown primary origin (CUP)), but that possess certain specific molecular, cellular, and histological characteristics typical of epithelial cells.

Epithelial cells Another subcategory is called caudate cells. They come from deep layers of a bladder. The cells with two nuclei are also categorized as transitional epithelial cells. Large number of cells with two nuclei or asymmetric cells can be found in urine from patients with transitional cell (urothelial) carcinomas.

The next three pairs of images show three successive stages of abnormal changes in the bronchial epithelium commonly found in smokers.
