Fibrillary Astrocytoma

Preferred Label : Fibrillary Astrocytoma;

NCIt related terms : Fibrous astrocytoma;

NCIt definition : The most frequent histological variant of diffuse astrocytoma. It is predominantly composed of fibrillary neoplastic astrocytes. Nuclear atypia is a diagnostic criterion but mitotic activity, necrosis and microvascular proliferation are absent. The occasional or regional occurrence of gemistocytic neoplastic cells is compatible with the diagnosis of fibrillary astrocytoma. (WHO);

Neoplastic status : Undetermined;

ICD-O code : 9420/3;
