https://www.selleckchem.com/MEK.html Astroblastoma is a very rare glial tumor derived from astroblasts. It has been controversial in terms of its features and diagnosis. The objective of this report is to present the findings of the high-grade astroblastoma with a good prognosis in a 21-year-old female who presented to us with diplopia and headache. While imaging led to the foremost differentials of pleomorphic xanthoastrocytoma and Ganglioglioma which are low-grade neoplasms, the final diagnosis was established on microscopy and immunohistochemistry after excision. Treatment protocol included surgery with postoperative radiotherapy and chemotherapy. Due to controversial and limited literature, this tumor poses difficulties in diagnosis and management. This is a rare, successfully managed case of astroblastoma with a positive outcome 5 years after the diagnosis was established. In this case report, we review the steps of diagnosis, the differentials, the pathological and histological features, and the management of this rare entity.Glioblastoma as second primary malignancy (SPM) has been reported after prostate cancer, meningiomas, Hodgkin's lymphoma. We report an extremely rare case of glioblastoma as SPM, occurring after remission of diffuse large B-cell lymphoma (DLBCL). Fifty-year-old male presented with loss of consciousness followed by right-sided weakness. He was treated with chemotherapy for DLBCL of the cervical lymph nodes, 5 years back. Present scans revealed well-defined intra-axial lesion in the left parietal lobe, suggestive of central nervous system (CNS) involvement by lymphoma. Left parieto-occipital craniotomy was performed and microscopic examination revealed the tumor to be Glioblastoma, WHO Grade IV. The tumor cells were positive for glial fibrillary acid protein and negative for leucocyte common antigen. He was treated by radiotherapy and temozolomide. Pathologic examination is a must for CNS lesions. Had it not been for the biopsy, the patient
