Initially described by Pflegrand and Tappeiner in 1959 as "angioendotheliomatosis proliferans systemisata" and in 2008 defined by the World Health Organization (WHO) as intravascular large B cell lymphomas (IVBCL), IVL is a type of extra-nodal large B cell lymphoma where growth is restricted to the lumina of the vessels, particularly the capillaries .
Scheithauer, "Reassessment of malignant "angioendotheliomatosis".
Immunohistochemical and cytogenetic studies indicate that malignant angioendotheliomatosis
is a primary intravascular (angiotropic) lymphoma.
Believing that the intravascular growth of malignant cells represented a neoplasm of the vascular endothelium, they described the disease as "angioendotheliomatosis
proliferans systemisata." In 1986 Sheibani et al (2) proved, via immunohistochemical investigation, that the cells of intravascular lymphoma were of lymphoid origin and described the disease as angiotropic (intravascular) large-cell lymphoma.
and Intravascular Histiocytopathy.--In the past, the term angioendotheliomatosis
was used to describe a condition that has now been renamed intravascular lymphomatosis (IVL).
Many terms have been used in the past to describe IVL, including angioendotheliomatosis
proliferans systematica and angiotropic large cell lymphoma.[1,2] However, most authors prefer the more descriptive term IVL.[3,4] The majority of IVL cases are of B-cell phenotype, as demonstrated by immunohistochemical,[3,4] Southern blot, and gene rearrangement studies.
For instance, the studies of Ansell et al and Wick et al have demonstrated that malignant angioendotheliomatosis
is a lymphoma and not a vascular tumor.
We favor the designation macroglossal angiodysplasia over macroglossal lymphangioendotheliomatosis, because the latter is liable to be confused with the entity of angioendotheliomatosis
, which is a malignant vasoformative neoplastic process of the central nervous system.
