| Summary: | Parotid lymphoepithelial carcinoma is extremely rare, and makes up only 0.4% of cases among the anaplastic variant of salivary gland carcinoma. We present a 63-year-old man who had progressive enlarging right neck swelling for one year. He sought treatment in another centre and underwent superficial parotidectomy, following an ultrasound assessment of the mass that was suggestive of a benign parotid tumour. There was no fine needle aspiration cytology or other radiological imaging performed prior to the surgery. However, the surgeon encountered difficulty intraoperatively and abandoned the surgery. The incisional biopsy of the tumour was reported as lymphoepithelial carcinoma. He then presented to us with the progression of the residual parotid malignant tumour. CT and MRI showed a locally aggressive parotid tumour that had infiltrated the subcutaneous tissue, external auditory canal, facial nerve, and multiple ipsilateral metastatic cervical lymph nodes. Subsequently, the patient underwent total parotidectomy with facial nerve resection, lateral temporal bone resection and ipsilateral modified radical neck dissection. The surgical site defect was reconstructed with anterolateral thigh myocutaneous free flap. Concurrent static facial reanimation with fascia lata sling was performed. The patient received adjuvant chemoradiation following the surgery. The extent of the local infiltration by the tumour and the resulting surgery could have been reduced if the tumour had been properly assessed and excised at the initial stage. A complete preoperative assessment of a parotid mass is essential to avoid misdiagnosis, unexpected intraoperative finding and delay in definitive treatment. |
