Imaging Features of Primary Alveolar Soft Part Sarcoma of the Parotid Gland

Alveolar soft part sarcoma (ASPS) is a rare soft tissue malignant neoplasm. In the study, we selected a 29-year-old woman presented with a painless mass on her right parotid gland for 6 months. The lesion was confirmed pathology as ASPS. In this paper, we analysed the imaging and biological behaviors of ASPS to understand the disease deeply.
