Synovial sarcoma of nerve
Scheithauer, BW; Amrami, KK; Folpe, AL; Silva, AI; Edgar, MA; Woodruff, JM; Levi, AD; Spinner, RJTumors of peripheral nerve are largely neuroectodermal in nature and derived from 2 elements of nerve, Schwann or perineurial cells. In contrast, mesenchymal tumors affecting peripheral nerve are rare and are derived mainly from epineurial connective tissue. The spectrum of the latter is broad and includes lipoma, vascular neoplasms, hematopoietic tumors, and even meningioma. Of malignant peripheral nerve neopl...

Galectin-3 expression is ubiquitous in tumors of the sellar region, nervous sys...
Rodriguez, FJ; Scheithauer, BW; Roncaroli, F; Silva, AI; Kovacs, K; Brat, DJ; Jin, LGalectin-3 expression has been reported in spindle cell oncocytoma, certain pituitary adenoma subtypes, astrocytomas, oligodendrogliomas, and meningiomas. We evaluated galectin-3 protein expression by immunohistochemistry in 201 cases of a variety of nervous system and sellar tumors, as well as mRNA expression by reverse transcription-polymerase chain reaction in formalin-fixed paraffin-embedded tissue in a sub...
Ganglioglioma of the neurohypophysis
Scheithauer, BW; Silva, AI; Parisi, JE; Kovacs, K; Horvath, EThe normal infundibulum and neurohypophysis consist entirely of neuronal processes, the neuronal cell bodies of which lie within the supraoptic and paraventricular nuclei of the hypothalamus and supportive glial cells or pituicytes. The finding of neurons within the neurohypophysis is exceedingly rare, as are ganglion cell tumors at this site. In this paper, we report a ganglion cell tumor of the neurohypophysi...

Synovial sarcoma of the sellar region
Scheithauer, BW; Silva, AI; Kattner, K; Seibly, J; Oliveira, AM; Kovacs, KPrimary sarcomas of the sellar region are uncommon, although a wide variety have been reported. To date, no cases of primary synovial sarcoma have been described as occurring at this site. We report an immunohistochemically and molecular genetically confirmed primary synovial sarcoma involving the sellar/parasellar region and cavernous sinus in an adult male. Subtotal resection and radiosurgery proved to be eff...
