Definitions for "Anaplastic large cell lymphoma"
Anaplastic large cell lymphoma (ALCL) is a type of T-cell non-Hodgkin's lymphoma. Most ALCL cases fall into one of two distinct forms: systemic ALCL, involving lymph nodes or extranodal sites; or primary cutaneous ALCL, involving skin nodules.
An aggressive (rapidly progressing) type of non-Hodgkinâ€(tm)s lymphoma that is usually of the T-cell type. The cancer cells express a marker called CD30 or Ki-1 on the surface, and may appear in the lymph nodes, skin, bones, soft tissues, lungs, or liver.
a fairly new type of large cell Non-Hodgkin's lymphoma. Most cases are T-cell or cell type unknown (null). It can be systemic in children or young adults or cutaneous (in/on the skin). Disease limited to the skin is quite indolent and remains localized to the skin with many examples of spontaneous remission. The systemic form can involve lymph nodes and extranodal sites acting aggressively but responds to chemotherapy used to treat other large cell lymphomas.
