Categories
- Angiolipoma (4)
- A benign neoplasm composed of a mixture of adipose tissue and blood vessels OCOSH Code C04.557.450.550.100_BD_BN_AT_AL
- Angiomyolipoma (1)
- A benign tumor containing vascular, adipose, and muscle elements. It occurs most often in the kidney with smooth muscle elements (angiolipoleiomyoma) in association with tuberous sclerosis. OCOSH Code C04.557.450.550.100_BD_BN_AT_AL
- Lipoma (9)
- A benign tumor composed of fat cells ( ADIPOCYTES). It can be surrounded by a thin layer of connective tissue (encapsulated), or diffuse without the capsule. OCOSH Code C04.557.450.550.400_BD_BN_AT_L
- Liposarcoma (16)
- A malignant tumor derived from primitive or embryonal lipoblastic cells. It may be composed of well-differentiated fat cells or may be dedifferentiated: myxoid ( LIPOSARCOMA, MYXOID), round-celled, or pleomorphic, usually in association with a rich network of capillaries. Recurrences are common and dedifferentiated liposarcomas metastasize to the lungs or serosal surfaces. OCOSH Code C04.557.450.550.420_BD_BN_AT_LS
- Myelolipoma (4)
- A rare benign tumor of the adrenal gland, several centimeters in diameter, composed in varying proportions of adipose tissue, lymphocytes, and primitive myeloid cells, probably a developmental abnormality. OCOSH Code C04.557.450.550.710_BD_BN_AT_ML
