We will describe a case of soft tissue sarcoma located at right cervical region of a 9-year-old male patient, mimicking malignant GNET, which can be considered as extragastrointestinal counterpart of this tumor. These tumors have poor prognosis. This is unique, possibly the first case of a soft tissue sarcoma resembling GNET.展开更多
文摘Malignant Gastrointestinal Neuroectodermal Tumor (GNET) is a recently described rare malignant neoplasm, resembling “clear cell sarcoma of tendons and aponeuroses” morphologically, immunohistochemically and molecular pathologically. We will describe a case of soft tissue sarcoma located at right cervical region of a 9-year-old male patient, mimicking malignant GNET, which can be considered as extragastrointestinal counterpart of this tumor. These tumors have poor prognosis. This is unique, possibly the first case of a soft tissue sarcoma resembling GNET.
