A 51 year old caucasian male presented with
headache
, facial nerve paresis and continuing contraction of the visual field. CT scan revealed a singular intracerebral contrast enhancing lesion in the left frontal lobe. Intraoperatively the tumour was well demarcated. Frozen sections showed a high grade glioma.
Paraffin
sections revealed, in addition to the gliomatous component, some sharply demarcated nests of meningothelial cells. Immunohistochemistry with glial fibrillary acidic protein and epithelial membrane antigen confirmed a collision tumour consisting of a glioblastoma WHO-grade IV and a meningothelial meningioma WHO-grade I. The coincidence of these two different tumours at the same time and the same location leads us to the speculation, that the collision tumour might have been caused by malignant transformation of a reactive astrogliosis surrounding the meningioma.

We present an extremely rare case of pinealoblastoma with retinoblastic differentiation in a 32-year-old woman who presented with a history of intermittent
headache
of 2 years duration and diminution of vision for 2 months which eventually lead to total loss of vision. The fundus examination showed bilateral secondary optic atrophy. She did not have any previous history of retinoblastoma. The family history was non-contributory.
Paraffin
section of the tumor showed a primitive neuroectodermal tumor with numerous Flexner-Wintersteiner rosettes and the tumor cells were strongly positive for synaptophysin and negative for GFAP, S-100 protein and epithelial membrane antigen. This is the first case in the literature of a sporadic case of pinealoblastoma with prominent retinoblastic differentiation as evidenced histomorphologically by the presence of numerous Flexner-Wintersteiner rosettes in an adult female.

We report a case of primary dural based osteosarcoma in the right fronto-temporal convexity in a 43-year-old female who presented with a short history of seizure and
headache
. Radiologic evaluation revealed a well defined brightly enhancing extra-axial lesion in the right fronto-temporal region with a dural tail around the sylvian fissure. The overlying bone was uninvolved.
Paraffin
section of the tumor showed plump cells with moderate nuclear and cellular pleomorphism with eosinophilic extracellular material (osteiod) between the cells. At a few places, lace like osteiod was seen encasing individual cells signifying osteiod being formed by tumor cells. Immunohistochemistry for EMA was focally positive and negative for S-100 protein and GFAP. A final histopathological diagnosis of dural based primary osteosarcoma of the right fronto-temporal region was rendered. To the best of our knowledge this will be the eighth such case in literature.
