Protoplasmic Astrocytoma

Preferred Label : Protoplasmic Astrocytoma;

NCIt definition : A rare variant of diffuse astrocytoma. It is predominantly composed of neoplastic astrocytes showing a small cell body with few, flaccid processes with a low content of glial filaments and scant GFAP expression. This lesion is not well defined and is considered by some authors as an occasional histopathological feature rather than a reproducibly identifiable variant. When occurring in children, this neoplasm may be difficult to separate from pilocytic juvenile astrocytoma. (Adapted from WHO);

Neoplastic status : Undetermined;

ICD-O code : 9410/3;
