Sarcomas are relatively uncommon Tumors, accounting for 1% of all malignancies. Sarcomas are classified according to the histologic tissue from which they are derived, and more than 30 histologic subtypes have been described. Soft tissue sarcomas arise from the mesenchyme, including muscle, endothelial cells, cartilage, and supporting elements. This sub classification also includes Tumors of peripheral nerve origin. Approximately 80% of sarcomas originate from soft tissues, while 20% arise from bone. Fewer than 5000 cases of sarcomas occur per year in the United States. Imaging studies are used to demonstrate the extent of tumour involvement.   Management depends on the type of sarcoma, although excision is the treatment of choice for many varieties. Head and neck sarcomas are rare Tumors, and this makes rigorous study of clinical behaviour difficult. As a result, treatment algorithms are drawn from retrospective case series and principles are derived from treatment of sarcomas at other sites, rather than from large clinical trials. Their study is also made more difficult by the diversity of histologic subtypes and the variable clinical behaviour. Furthermore, the confining anatomy and proximity to vital structures makes even adherence to traditional margin-driven therapy challenging. Citations are important for a journal to get impact factor. Impact factor is a measure reflecting the average number of citations to recent articles published in the journal. The impact of the journal is influenced by impact factor, the journals with high impact factor are considered more important than those with lower ones. This information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports.
