    S3.02 The histological type and subtype of the tumour must be documented wherever possible. CS3.02a Accepting the limitations of sampling and with the use of diagnostic common sense, tumour type should be assigned according to the WHO system 17, wherever possible. (See Appendix 4 for full list). CS3.02b If precise tumour typing is not possible, generic descriptions to describe the tumour may be useful (eg myxoid, pleomorphic, spindle cell, round cell etc), together with the growth pattern (eg fascicular, sheet-like, storiform etc). (See G3.01). CS3.02c If the reporting pathologist is unfamiliar or lacks confidence with the myriad possible diagnoses, then at this point a decision to send the case away without delay for an expert opinion would be the most sensible option. Referral to the pathologist at the nearest Regional Sarcoma Service would be appropriate in the first instance. Further International Pathology Review may then be obtained by the treating Regional Sarcoma Multidisciplinary Team if required. Adequate review will require submission of full clinical and imaging information as well as histological sections and paraffin block material.

    The Role of Cytogenetics and Molecular Diagnostics in the Diagnosis of Soft-Tissue Tumors Julia a Bridge

    Modern Pathology (2014) 27, S80–S97 S80 & 2014 USCAP, Inc All rights reserved 0893-3952/14 $32.00 The role of cytogenetics and molecular diagnostics in the diagnosis of soft-tissue tumors Julia A Bridge Department of Pathology and Microbiology, University of Nebraska Medical Center, Omaha, NE, USA Soft-tissue sarcomas are rare, comprising o1% of all cancer diagnoses. Yet the diversity of histological subtypes is impressive with 4100 benign and malignant soft-tissue tumor entities defined. Not infrequently, these neoplasms exhibit overlapping clinicopathologic features posing significant challenges in rendering a definitive diagnosis and optimal therapy. Advances in cytogenetic and molecular science have led to the discovery of genetic events in soft- tissue tumors that have not only enriched our understanding of the underlying biology of these neoplasms but have also proven to be powerful diagnostic adjuncts and/or indicators of molecular targeted therapy. In particular, many soft-tissue tumors are characterized by recurrent chromosomal rearrangements that produce specific gene fusions. For pathologists, identification of these fusions as well as other characteristic mutational alterations aids in precise subclassification. This review will address known recurrent or tumor-specific genetic events in soft-tissue tumors and discuss the molecular approaches commonly used in clinical practice to identify them. Emphasis is placed on the role of molecular pathology in the management of soft-tissue tumors. Familiarity with these genetic events

Two cases of the tumors, who presented with a painless, relatively hard mass on the oral mucosa, were studied. These were consisted of a well-circumscribed mass of fatty tissue with chondroid and significant fibrous component intermixed with the lobules of fat cells with chondroid and woven bone component, respectively. Immunohistochemical study revealed that peripheral spindle cells around chondroid tissue stained diffusely for S-100 α & β and Sox-9, though peripheral spindle cells around osteoid tissue only stained for RUNX-2. According to review of the literature, lipoma/fibrolipoma with osseous and/or chondroid differentiation was 18 cases.

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Since the mechanisms of the developmental processes of tumors remain unclear, early detection and early treatment of the tumors is necessary to save patients with malignant tumors. Therapies currently available to patients are surgery, chemotherapy, and radiotherapy. However, there are many patients who cannot be saved by such therapies. In this study, we found the common fea- tures of various tumor tissues, and we demonstrated the effect of therapeutics that target them by using experimental rats with spontaneous tumors. 26 kinds of human tumors (epithelial or me- senchymal origin, and malignant or benign) and Sprague-Dawley rats with spontaneous mammary gland tumors were examined by light and electron microscope. To detect of mast cells and leuko- triene receptor, toluidine blue stain and immunohistochemical stain were performed. The rats were orally administered one of leukotriene receptor antagonists. We found that the presence of numerous mast cells and expression of leukotriene receptors in various tumor (human tumors and rat spontaneous tumors).
