(1) Neoplasms with no differentiation are said to be anaplastic.

(2) Adenocarcinomas and large cell anaplastic carcinomas tend to occur more peripherally in lung.

(3) Conclusion anaplastic ependymoma rapid growth, poor clinical course, biological behavior should be defined as malignant.

(4) To qualify as a "malignant" or "anaplastic" meningioma (grade III), one need to find at least 20 mitoses per 10 high power field.

(5) Anaplastic tumors are treated with radiation therapy and 1 year of PCV chemotherapy.

(6) Results There were 7 cases with anaplastic astrocytoma, 3 cases with glioblastoma multiforme, 1 cases with oligodendroglioma, 1 cases with lower grade glioma.

(7) Conclusion The result suggest that anaplastic astrocytoma and gemistocytic astrocytoma are more malignant and more recurrent.

(8) Expanding the Spectrum of Malignant Progression in Solitary Fibrous Tumors: A Study of 8 Cases With a Discrete Anaplastic Component-Is This Dedifferentiated SFT?

(9) Purpose To probe into morphologic and immunophenotypic features of anaplastic large cell lymphoma ( ALCL ).

(10) Arising centrally in this lung and spreading extensively is a small cell anaplastic ( oat cell ) carcinoma.

(11) Postoperative pathological results revealed that 79 cases(86.8%) were low-grade gliomas, 4 cavernous hemangiomas, 4 anaplastic astrocytomas, 2 gliosis, 1 arteriovenous malformation, and 1 gliosarcoma.

(12) This tour will examine the left parietal lesion, found at biopsy to be anaplastic astrocytoma.
