      Abstract

      Ectopic thymic carcinoma (ETC) of the parotid gland is a rare entity. This report describes the case of a 52-year-old man with a painless mass in the right parotid gland. Magnetic resonance imaging (MRI) showed a biphasic mass consisting of a central segment and a peripheral segment. The patient underwent a superficial parotidectomy, and point-to-point correspondence sampling for analysis based on MRI findings was performed. The pathological finding was ETC, and there was an excellent association between MRI characteristics and histopathological findings. Subsequently, the patient underwent postoperative radiation therapy. At the 9-month follow-up, he had recovered well without facial paralysis, and there was no evidence of recurrence or metastasis. This report describes the clinical, radiological, and pathological features of the ETC.
