|
Sarcoma, Clear Cell
|
D018227 |
[A sarcoma of young adults occurring in the lower extremities and acral regions. It is found intimately bound to tendons as a circumscribed but unencapsulated melanin-bearing tumor of neuroectodermal origin. Clear cell sarcoma is associated with a specific t(12;22)(q13;q12) translocation.

Sarcoma, Endometrial Stromal
|
D018203 |
[A highly malignant subset of neoplasms arising from the endometrial stroma. Tumors in this group infiltrate the stroma with a wide range of atypia cells and numerous mitoses. They are capable of widespread metastases (NEOPLASM METASTASIS).

|
Sarcoma, Ewing
|
D012512 |
[A malignant tumor of the bone which always arises in the medullary tissue, occurring more often in cylindrical bones. The tumor occurs usually before the age of 20, about twice as frequently in males as in females.

Sarcoma, Experimental
|
D012513 |
[Experimentally induced neoplasms of CONNECTIVE TISSUE in animals to provide a model for studying human SARCOMA.

|
Sarcoma, Kaposi
|
D012514 |
[A multicentric, malignant neoplastic vascular proliferation characterized by the development of bluish-red cutaneous nodules, usually on the lower extremities, most often on the toes or feet, and slowly increasing in size and number and spreading to more proximal areas. The tumors have endothelium-lined channels and vascular spaces admixed with variably sized aggregates of spindle-shaped cells, and often remain confined to the skin and subcutaneous tissue, but widespread visceral involvement may occur. Kaposi's sarcoma occurs spontaneously in Jewish and Italian males in Europe and the United States. An aggressive variant in young children is endemic in some areas of Africa. A third form occurs in about 0.04% of kidney transplant patients. There is also a high incidence in AIDS patients. (From Dorland, 27th ed & Holland et al., Cancer Medicine, 3d ed, pp2105-7) HHV-8 is the suspected cause.

|
Sarcoma, Myeloid
|
D023981 |
[An extramedullary tumor of immature MYELOID CELLS or MYELOBLASTS. Granulocytic sarcoma usually occurs with or follows the onset of ACUTE MYELOID LEUKEMIA.
] |
|
Sarcoma, Small Cell
|
D018228 |
[A sarcoma characterized by the presence of small cells, cells measuring 9-14 micrometers with a faint or indistinct rim of cytoplasm and an oval-to-elongated nucleus with relatively dense chromatin. (From Segen, Dictionary of Modern Medicine, 1992)

|
Sarcoma, Synovial
|
D013584 |
[A malignant neoplasm arising from tenosynovial tissue of the joints and in synovial cells of tendons and bursae. The legs are the most common site, but the tumor can occur in the abdominal wall and other trunk muscles. There are two recognized types: the monophasic (characterized by sheaths of monotonous spindle cells) and the biphasic (characterized by slit-like spaces or clefts within the tumor, lined by cuboidal or tall columnar epithelial cells). These sarcomas occur most commonly in the second and fourth decades of life. (From Dorland, 27th ed; DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1363)

Sarcomeres
|
D012518 |
[The repeating contractile units of the MYOFIBRIL, delimited by Z bands along its length.

Sarcopenia
|
D055948 |
[Progressive decline in muscle mass due to aging which results in decreased functional capacity of muscles.

Sarcophagidae
|
D058493 |
[Family of flies in the order DIPTERA, commonly known as flesh flies. They lay their eggs in dead or decaying matter or open wounds.

|
Sarcoplasmic Reticulum
|
D012519 |
[A network of tubules and sacs in the cytoplasm of SKELETAL MUSCLE FIBERS that assist with muscle contraction and relaxation by releasing and storing calcium ions.
] |
|
Sarcoplasmic Reticulum Calcium-Transporting ATPases
|
D053498 |
[Calcium-transporting ATPases that catalyze the active transport of CALCIUM into the SARCOPLASMIC RETICULUM vesicles from the CYTOPLASM. They are primarily found in MUSCLE CELLS and play a role in the relaxation of MUSCLES.
] |
|
Sarcoptes scabiei
|
D012520 |
[A species of mite that causes SCABIES in humans and sarcoptic mange in other animals. Specific variants of S. scabiei exist for humans and animals, but many have the ability to cross species and cause disease.
] |
|
Sarcoptidae
|
D040021 |
[Family of MITES, in the superfamily Sarcoptoidea, order Astigmata. They are slow moving, obligate PARASITES that infect MAMMALS and BIRDS. The species SARCOPTES SCABIEI causes SCABIES.

Sarcosine
|
D012521 |
[An amino acid intermediate in the metabolism of choline.
] |
|
Sarcosine Dehydrogenase
|
D050892 |
[A LIVER mitochondrial matrix flavoenzyme that catalyzes the oxidation of SARCOSINE to GLYCINE and FORMALDEHYDE. Mutation in the enzyme causes sarcosinemia, a rare autosomal metabolic defect characterized by elevated levels of SARCOSINE in BLOOD and URINE.
