Figure 1 Histopathologic section of the primary tumor. The tumor was composed of spindle and epithelioid cells, which were predominantly arranged in spiral and lace-like shape (HE staining × 400).

Figure 2 Ultrasonography of cervical mass: The mass was hypoechoic, with a smooth border and un-even internal echo.

Figure 3 Computed tomography: The mass appeared as a low density cyst with clear edge without contrast enhancement.

Figure 4 Positron emission tomography-computed tomography: FDG accumulated unevenly in the cervical mass and multiple lymph nodes in mediastinum.

Figure 5 Histopathologic section of the cervical tumor (HE staining). The epithelioid cells were arranged in sheets, with abundant eosinophilic cytoplasm and prominent nuclei (HE staining × 400).
