Anaplastic astrocytoma of brain – http://id.who.int/icd/entity/884889079

A diffusely infiltrating, WHO grade III astrocytoma with focal or dispersed anaplasia, and a marked proliferative potential. It may arise from a low-grade astrocytoma, but it can also be diagnosed at first biopsy, without indication of a less malignant precursor lesion. It has an intrinsic tendency for malignant progression to glioblastoma. (WHO)
