Myeloid Sarcoma Pathology Definition. Myeloid sarcoma is a tissue mass that effaces tissue architecture. It is composed of blasts (ie, granulocytic, monocytic, erythroid, or megakaryocytic precursors) and occurs at anatomic sites outside of the bone marrow.he morphologic features of myeloid sarcoma are similar to those of the various subtypes of AML, except in tissue form. In granulocytic sarcoma, the tumor mass is composed of granulocytic precursors with varying degrees of differentiation.

- Sarcoma: One of a group of tumors usually arising from connective tissue. Most sarcomas are malignant. Many types are named after the type of cell, tissue, or structure involved, as in angiosarcoma, chondrosarcoma, fibrosarcoma, liposarcoma,and osteosarcoma. Last Editorial Review: 8/28/2013.

Sarcolemma Click here for more textbooks. Sarcolemma is the name of the cell membrane that encloses each muscle cell, specifically. cells (muscle cell = muscle fibre = muscle fiber).Each sarcolemma has a similar biochemical composition to that of a plasmalemma, which is another word for a (general) cell membrane.lick here for more textbooks.

Sarcoma A sarcoma (from the Greek σάρξ sarx meaning flesh) is a cancer that arises from transformed cells of mesenchymal origin. Thus, malignant tumors made of cancellous bone, cartilage, fat, muscle, vascular, or hematopoietic tissues are, by definition, considered sarcomas.This is in contrast to a malignant tumor originating from epithelial cells, which are termed carcinoma.Human sarcomas are quite rare. Common malignancies, such as breast, colon, and lung cancer, are almost always carcinoma.his is in contrast to a malignant tumor originating from epithelial cells, which are termed carcinoma.

Neoplasm 1 Secondary neoplasm refers to any of a class of cancerous tumor that is either a metastatic offshoot of a primary tumor, or an apparently unrelated tumor that increases in frequency following certain cancer treatments such as chemotherapy or radiotherapy. neoplasm can be benign, potentially malignant (pre-cancer), or malignant (cancer). 1  Benign tumors include uterine fibroids and melanocytic nevi (skin moles). 2  They are circumscribed and localized and do not transform into cancer.

Carcinosis Carcinosis, or carcinomatosis, is disseminated cancer, forms of metastasis, whether used generally or in specific patterns of spread.arcinomatosis is often restricted to tumors of epithelial origin, adenocarcinomas, while sarcomatosis describes the dissemination of tumors of mesenchymal origin, sarcomas.

malignant melanoma Malignant Melanoma. Definition. Malignant melanoma is a type of cancer arising from the melanocyte cells of the skin. Melanocytes are cells in the skin that produce a pigment called melanin. Malignant melanoma develops when the melanocytes no longer respond to normal control mechanisms of cellular growth.

What is a Sarcomere? A sarcomere is the basic functional unit of striated muscle, which is to say, it’s the basic building block of most muscle cells. In the human body, each muscle is made up of multiple bundles of muscle fibers. These muscle fibers, in turn, are comprised of numerous finer strands called myofibrils.

sarcoma sarcoma. A tumor, often highly malignant, composed of cells derived from connective tissue such as bone, cartilage, muscle, blood vessel, or lymphoid tissue; sarcomas usually develop rapidly and metastasize through the lymph channels.

Carcinoma [edit on Wikidata] 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.

- A breast neoplasm is an abnormal mass of tissue in the breast as a result of neoplasia. A breast neoplasm may be benign, as in fibroadenoma, or it may be malignant, in which case it is termed breast cancer.Either case commonly presents as a breast lump. Approximately 7% of breast lumps are fibroadenomas and 10% are breast cancer, the rest being other benign conditions or no disease.alignant neoplasms (breast cancer). Among women worldwide, breast cancer is the most common cause of cancer death. Malignant breast neoplasm is cancer originating from breast tissue, most commonly from the inner lining of milk ducts or the lobules that supply the ducts with milk.

- A teratoma is a tumor with tissue or organ components resembling normal derivatives of more than one germ layer. Although the teratoma may be monodermal or polydermal (originating from one or more germ layers), its cells may differentiate in ways suggesting other germ layers.

Neoplasm Neoplasm (from Ancient Greek νέος- neo new and πλάσμα plasma formation, creation) is an abnormal growth of tissue, and when also forming a mass is commonly referred to as a tumor or tumour.This abnormal growth (neoplasia) usually but not always forms a mass. Secondary neoplasm refers to any of a class of cancerous tumor that is either a metastatic offshoot of a primary tumor, or an apparently unrelated tumor that increases in frequency following certain cancer treatments such as chemotherapy or radiotherapy.

- Melanoma is a disease in which malignant (cancer) cells form in melanocytes (cells that color the skin). The skin is the body's largest organ. It protects against heat, sunlight, injury, and infection. Skin also helps control body temperature and stores water, fat, and vitamin D.
