Abstract

LEC (Lymphoepithelial Carcinoma) arising in the salivary glands is extremely rare; it was originally described by Hilderman in 1962 and comprises only 0.4% of salivary carcinomas.[1,2] It is identified by histopathological features of undifferentiated malignant epithelial cells within lymphoid stroma cells.[3] It has a female preponderance. It is associated with Epstein-Barr virus infection; the Arctic Inuit, Japanese, and Southern Chinese populations have a strong association with EBV infection.[4] The histology is closely related to nasopharyngeal carcinoma; hence, it has to be ruled out. Commonly found in foregut derivatives, salivary glands, thymus, stomach and liver. However, other anatomical locations, such as the bladder, lacrimal glands, ovaries, cervix, and skin, were also reported.[5] The mainstay of treatment of parotid LEC is surgical resection with adequate safety margins for patients with resectable tumours.[2] LEC is highly radiosensitive; hence, surgery with adjuvant radiotherapy improves the patients' long-term survival compared to those treated with surgery alone. We present this rare case of primary lymphoepithelial carcinoma of the left parotid gland, which was treated with superficial parotidectomy followed by adjuvant radiotherapy.


Our case report describes an 85-year-old female diagnosed with primary lymphoepithelial carcinoma of the left parotid, treated with left superficial parotidectomy with adjuvant radiotherapy. There were no recurrences noted during one year of follow-up; currently, the patient is under regular follow-up.
