====== Spongioblastoma multiforme ====== During the early 19th century, [[glioblastoma]] was considered of [[mesenchyma]]l origin and was defined as a [[sarcoma]]. In [[1863]], [[Rudolf Ludwig Karl Virchow]] demonstrated its [[glia]]l origin ((Virchow R. Pathologie In Die Krankhaften Geschwülste. Berlin. 1864-1865.)) , and in [[1914]] Mallory proposed the term [[glioblastoma multiforme]]. However, it was not until [[1925]] that Globus and Strass presented a complete description of the neoplasm, at which point the most common term became [[spongioblastoma multiforme]]. Finally, in [[1926]], Bailey and Cushing successfully reintroduced the term originally proposed by Mallory: glioblastoma multiforme.
