Gliosarcoma: a case with unusual epithelial feature.
Astrocytic tumors, particularly gliosarcoma, may contain epithelial features in the form of trabecular, adenoid, papillary arrangement, and squamous metaplasia. A case of gliosarcoma with unusual epithelial feature is described. The patient was a 60-year-old male with frequent seizures. The mass was 4 cm and in the left frontal lobe. Trabecular or rarely adenoid arrangement of neoplastic astroc...
متن کاملConversion of a Gemistocytic Astrocytoma to a Fibrillary Astrocytoma after Temozolomide and Radiation Therapy
In most instances, gemistocytic astrocytoma progresses to anaplastic astrocytoma at the time of recurrence. Here, we report an unusual case where a gemistocytic astrocytoma converted to a more benign fibrillary histology after temozolomide/radiation therapy. We present the case of a 26-year-old woman with a history of fibrillary astrocytoma that was followed over a span of eight years and under...
متن کاملMalignant Intracerebral Nerve Sheath Tumors: A Case Report with Review of the Literature
The occurrence of benign nerve sheath tumors within the neuroaxis is uncommon. Even rarer is the finding within brain parenchyma, termed malignant intracerebral nerve sheath tumors (MINST). We present a case of MINST which occurred in the frontal lobe of an 18-year-old male that recurred almost 4 years later. Imaging demonstrated a 4.0 cm lesion with an associated mass effect. He underwent a ri...
متن کاملCongenital gliosarcoma: detailed clinicopathologic documentation of a rare neoplasm.
Congenital brain tumors are rare. Clinically, they often result in macrocrania, hydrocephalus, and focal neurologic deficits. Fetal onset may result in dystocia and stillbirth. Antenatal detection is becoming more common as the result of neuroimaging, and modalities such as magnetic resonance imaging can assist in narrowing the pathologic differential diagnoses. Teratomas and astrocytomas appea...
متن کاملThe glial and mesenchymal elements of gliosarcomas share similar genetic alterations.
The cellular origin of the sarcomatous component of gliosarcomas is controversial. It is not clear if the sarcoma arises in transition from the glial cells that comprise the gliomatous component or independently arises from non-neoplastic mesenchymal cells of the tumor stroma. Using comparative genomic hybridization (CGH) along with cytogenetic analysis, fluorescence in situ hybridization (FISH...
