From OncologyChannel: "Small noncleaved cell lymphoma (SNCL) is a classification that, in general, has been replaced by the terms Burkitt's lymphoma and Burkitt-like (or non-Burkitt's) lymphoma. In children, most SNCLs are Burkitt's lymphomas, whereas most adult SNCLs are Burkitt-like lymphomas.
Burkitt's lymphoma tends to occur most often in children and in adults with compromised immune systems.
There are three distinct forms of this disease: endemic, sporadic, and immunodeficient.
Endemic Burkitt's lymphoma is seen among the young of equatorial Africa. It frequently affects the jaws of children with developing molar teeth; experts suggest that growth factors may be responsible for the site-specific nature of this tumor.
Sporadic Burkitt's lymphoma often involves the abdomen, and it spreads to the bone marrow in about 20% of patients.
Immunodeficient Burkitt's lymphoma affects patients with abnormal immune systems (e.g., patients with HIV)."
