[A comparative study of "angioblastic meningioma", hemangiopericytoma and cerebellar hemangioblastoma].
Forty-nine cases of the so-called "angioblastic meningioma", six cases of cerebellar hemangioblastoma, and four cases of soft tissue hemangiopericytoma were studied with HE, reticulin stainings, and immunohistochemical reaction with Vimentin, EMA, GFAP, S-100, and UEA-1 antibodies. The results showed that among the three subtypes of "angioblastic meningioma", namely, the hemangiomatous (H), the hemangioblastic (AB), and the hemangiopericytic (P) types, (1) type H belongs to true meningioma; (2) most of type P are almost identical with soft tissue hemangiopericytoma and different from true meningiomas, therefore belong to hemangiopericytoma arising from pericytes; however (3) some true meningiomas may appear as hemangiopericytoma histologically; (4) a few of AB are very similar to cerebellar hemangioblastoma and thus should be considered as supratentorial hemangioblastoma, while most of AB are still true meningiomas.
