A Typical Angiosarcoma of the Posterior Mediastinum: One Case Report and Review of the Literature

چکیده
Angiosarcomas are most often encountered as sporadic cutaneous lesions, typically in the scalp or face of an elderly patient. However, angiosarcomas can occur in virtually any anatomic site, including the deep soft tissue, breast, visceral organs, and bone. Primary angiosarcomas of the posterior mediastinum are extremely rare. According to the papers of other cases reported on angiosarcoma in mediastinum, invasive biological behavior exist, such as ill-defined margin , heterogeneous density and local involvement of lung and ribs or vertebra. This case showed a well-defined, homogeneous mass without metastasis. We herein report an atypical case of the posterior mediastinum and present the CT imaging, clinicopathologic and immunohistochemical features of this tumor. In addition, the differential diagnoses are discussed.
