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.
我们报告一例腮腺复发性肌上皮瘤，该肿瘤最初表现为皮肤肿物。患者耳后皮下有一肿物，初步诊断为皮肤肌上皮瘤，两年前在某医院皮肤科切除。肿瘤位于颈阔肌上方，被认为是不含腮腺结构的皮肤肌上皮瘤。患者约20年前曾行腮腺部分切除术。首次来我院就诊时，未发现面神经麻痹或颈部淋巴结肿大的迹象。影像学检查显示腮腺有一多结节状生长肿物，位于耳后皮肤下方，遂行腮腺全切除术。我们认为，即使出现皮肤肿物，术前也应通过计算机断层扫描（CT）或磁共振成像（MRI）检查皮肤肿物与腮腺之间的关系。同时也需要进行长期的持续随访。
