[Rare malignant tumor of the parotid gland. Myoepithelial carcinoma]. / Seltener maligner Tumor der Gl. parotis. Myoepitheliales Karzinom.

A parotid mass in a 62-year-old woman presented intraoperatively as a highly malignant tumor with facial nerve infiltration. Classification by means of rapid section histology was not possible. Immunohistochemical studies were necessary to diagnose this rare case of myoepithelial carcinoma of the parotid gland. We performed a total parotidectomy including partial nerve resection and neck dissection on the tumor side. The patient was referred to radiotherapy postoperatively.
