  Malignant Peripheral Nerve Sheath Tumors with t(X;18). A Pathologic and Molecular Genetic Study

  摘要：

  Spindle cell sarcomas often present the surgical pathologist with a considerable diagnostic challenge. Malignant peripheral nerve sheath tumor, leiomyosarcoma, fibrosarcoma, and monophasic synovial sarcoma may all appear similar histologically. The application of ancillary diagnostic modalities, such as immunohistochemistry and electron microscopy, may be helpful in the differentiation of these tumors, but in cases in which these adjunctive: techniques fail to demonstrate any more definitive evidence of differentiation, tumor categorization may remain difficult. Cytogenetic and molecular genetic characterization of tumors have provided the basis for the application of molecular assays as the newest components of the diagnostic armamentarium. Because the chromosomal translocation t(X;18) has been observed repeatedly in many synovial sarcomas, it has been heralded as a diagnostic hallmark of synovial sarcoma To formally test the specificity of this translocation for the diagnosis of synovial sarcoma, RNA extracted from formalin-fixed, parrafin-embedded tissue from a variety of soft tissue and spindle cell tumors was evaluated fbr the presence of t(X;18) by reverse transcriptase-polymerase chain reaction. Although 85% of the synovial sarcomas studied demonstrated t(X;18), 75% of the malignant peripheral nerve sheath tumors in our cohort also demonstrated this translocation. We conclude that the translocation t(X;18) is not specific to synovial sarcoma and discuss the implications of the demonstration of t(X;18) in a majority of malignant peripheral nerve sheath tumors.

  Carbazole reacts with n-BuLi and fluorosilanes to give the lithium carbazolide (1) which crystallizes as a dimer from THF. In the reactions of 1 and difluorosilanes, F₂SiR₂, the carbazolylsilanes C₁₂H₈N-SiFR₂ (2 - 4 R = Me (2), i Pr (3), t-Bu (4)), are obtained. Bis(carbazolyl)silanes, (C₁₂H₈N)₂SiFR, are formed in the reaction of 1 with trifluorosilanes, F₃SiR, in a molar ratio of 2:1, R = t-Bu (5), Ph (6), Me (7). Using F₃SiMe and 1 in a molar ratio of 1:3 the tris(carbazolyl)silane (C₁₂H₈N)₃SiMe (8) is isolated. The carbazolylfluorosilane 3 reacts with n-BuLi to give 1 and n-butyldiisopropylfluorosilane, or with lithium pyrrolide to give carbazolyl(-diisopropyl)pyrrolylsilane (9). Lithiumpyrrolide cleaves the Si-NC₁₂H₈-bond of 9 and forms the diisopropyl-bis(pyrrolyl)silane 10.

  The crystal structures of 5, 6 and 7 have been determined and are discussed.
