We are reporting a case of recurrent myoepithelioma of the parotid gland, that emerged as a cutaneous mass. She had a retroauricular subcutaneous mass with an underlying diagnosis of a cutaneous myoepithelioma, which was excised at a hospital’s Dermatology Department 2 years earlier. The tumour was observed above the platysma and it was considered as a cutaneous myoepithelioma without the parotid gland structures. She had undergone a partial parotidectomy approximately 20 years earlier. At her first visit to our department, there was no evidence of facial nerve palsy or cervical lymphadenopathy. The radiological findings showed a multinodular growing mass of the parotid gland, just beneath the retroauricular skin and a total parotidectomy was performed. It was considered that even if the cutaneous mass emerged, the relationship between the cutaneous mass and the parotid gland should be pre-surgically examined by computed tomography (CT) or Magnetic resonance image (MRI). A long-term continuous follow-up was also needed.
