Myoepithelial carcinoma (MC), also known as malignant myoepithelial neoplasm, is more common in the parotid glands of the head and neck.

The current reports of non-parotid MC are still rare, and epididymal-derived MC has not been reported previously. Simultaneously, we explore the role of EWSR1 fusion as a predicting marker and further reveal the origin of MC to provide new ideas for its diagnosis and treatment.
