What is parotid tumor?
Parotid tumors are abnormal growths of cells (tumors) that form in the parotid glands. The parotid glands are two salivary glands that sit just in front of the ears on each side of the face. Salivary glands produce saliva to aid in chewing and digesting food.

Which of the following cancers arise from connective tissue?
Sarcoma. Sarcoma refers to cancer that originates in supportive and connective tissues such as bones, tendons, cartilage, muscle, and fat.
What is difference between carcinoma and adenocarcinoma?
Carcinoma is the most common form of cancer. It starts in the epithelial tissue of your skin or internal organs. Adenocarcinoma is a subtype of carcinoma. It grows in the glands that line the insides of your organs.
What are epithelial cancers?
(eh-pih-THEE-lee-ul KAR-sih-NOH-muh) Cancer that begins in the cells that line an organ.
What is carcinoma in situ?
Carcinoma in situ (CIS) is a group of abnormal cells that are found only in the place where they first formed in the body (see left panel). These abnormal cells may become cancer and spread to nearby normal tissue (see right panel).
Is an adenoma cancerous?
By definition, adenomas are not cancerous. However, you should view them as precancerous. They can sometimes turn into cancer. It's important for your healthcare provider to monitor adenomas and treat them if necessary.
What is the name of the cancer that is arising from gland tissue in a lining membrane?
Most cancers of the breast and large intestine ( COLON) are adenocarcinomas.
What is adenocarcinoma?
adenocarcinoma (bladder) A tumour that may be primary and result from differentiation of a urothelial carcinoma. It may arise in a polyp or from urachal remnant tumours and resemble colorectal tumours, or it can be the recipient of prostate or colorectal metastases.

Called also clear cell carcinoma and mesonephroma. adenocarcinoma of the lung a type of bronchogenic carcinoma made up of cuboidal or columnar cells in a discrete mass, usually at the periphery of the lungs.
What is clear cell adenocarcinoma?
clear cell adenocarcinoma a rare malignant tumor of the female genital tract, resembling a renal cell carcinoma and containing tubules or small cysts with some cells that are hobnail-shaped and others whose cytoplasm is clear, containing abundant glycogen and inconspicuous stroma. It may occur in the ovary, uterus, cervix, or vagina.
What are the four categories of adenocarcinoma?
The World Health Organization recognizes four categories of adenocarcinoma: acinar, papillary, bronchioalveolar, and solid carcinoma with mucus formation; it can be further subclassified into well, moderate, and poorly differentiated forms.
Can fusion cause leukaemia?
"Previously it was thought that fusion genes pretty much only caused leukaemia, but our group can now show that this type of cancer gene is also common in glandular cancer ," says Stenman.
Which tissue is derived from the third or middle primary germ layer?
Glands that form secretions in the digestive tract. Epithelial tissue derived from ectoderm is generally squamous epithelium; epithelial tissue derived from endoderm is essentially glandular epithelium. There are a variety of body tissues derived from the third or middle primary germ layer known as the mesoderm.
What is the derivation of tissue?
Derivation of Tissues. Cells that are similar in structure tend to group themselves together and form tissues. A tissue, then, is composed of a group of cells that are similar in structure and perform one or more common functions. Some tissues contain intercellular material which is very important in the performance of a particular function ...
Where does epithelial tissue come from?
In fact, epithelial tissue can be derived from either the ectoderm or endoderm. The epithelial tissue derived from the endoderm includes the epithelial lining of the digestive tract, except at the open ends, and the epithelial lining of all hollow structures formed as outpockets in the digestive tract. This includes:
What is the lining of the bladder?
The linings of these cavities are composed of a single layer of cells called mesothelium. A few epithelial cells are of mesodermal origin, e.g. endometrium of the uterus, vaginal epithelium, and mucosa of the bladder. Endothelium derived from mesoderm lines the blood and lymphatic vessels and the walls of the heart.
Where does endothelium come from?
Endothelium derived from mesoderm lines the blood and lymphatic vessels and the walls of the heart. In the capillaries where the endothelium is covered only by a basement membrane, diffusion takes place. It is surrounded elsewhere by supportive layers of connective tissue and smooth muscle.

The parenchyma of the liver including communicating or connecting ducts. The lining of the pharynx and respiratory tract (except the nose). This includes the lungs and the passageways leading from the pharynx to the lungs. Glands that form secretions in the digestive tract.
What is intercellular material?
Some tissues contain intercellular material which is very important in the performance of a particular function belonging to that tissue. The body tissues and organs develop from the three primary germ layers that form during the growth process of the human embryo.

carcinoma – this cancer begins in the skin or in tissues that line or cover internal organs. There are different subtypes, including adenocarcinoma, basal cell carcinoma, squamous cell carcinoma and transitional cell carcinoma. leukaemia – this is cancer of the white blood cells.
What is the name of the cancer that starts in the cells of the immune system?
leukaemia – this is cancer of the white blood cells. It starts in the tissues that make blood cells such as the bone marrow. lymphoma and myeloma – these cancers begin in the cells of the immune system. brain and spinal cord cancers – these are known as central nervous system cancers.
What is the term for cancer of the white blood cells?
Leukaemias – cancers of blood cells. Leukaemia is cancer of the white blood cells. The bone marrow makes too many white blood cells. The blood cells are not fully formed and so they don't work properly. The abnormal cells build up in the blood.

What is a transitional cell?
Transitional cell carcinoma. Transitional cells are cells that can stretch as an organ expands. They make up tissues called transitional epithelium. An example is the lining of the bladder. Cancers that start in these cells are called transitional cell carcinoma.
What are the main tissues of sarcoma?
Sarcomas start in connective tissues. These are the supporting tissues of the body. Connective tissues include the bones, cartilage, tendons and fibrous tissue that support organs. Sarcomas are much less common than carcinomas. There are 2 main types: bone sarcomas.
How many types of cancer are there?
There are more than 200 types of cancer and we can classify cancers according to where they start in the body, such as breast cancer or lung cancer. We can also group cancer according to the type of cell they start in. There are 5 main groups. These are: carcinoma – this cancer begins in the skin or in tissues that line or cover internal organs.
