Lymphoepithelial carcinoma, also known as malignant lymphoepithelial lesion or lymphoepithelioma, is a rare tumor in salivary glands. Lymphoepithelial carcinoma has a characteristic histological findings comprising irregularly-shaped nests of malignant epithelial cells within a lymphocyte-rich stroma, occasionally forming lymphoid follicles. We recently experienced a case of fine needle aspiration cytology (FNAC) of lymphoepithelial carcinoma of parotid gland in a 61-year-old male. The FNAC yielded a hypercellular smear of many irregular clusters of malignant epithelial cells in the background of lymphoid stroma.

Lymphoepithelial carcinoma is an extremely rare malignant tumor, especially those localized at the head and neck region. The histological prototype of lymphoepithelial carcinoma is undifferentiated nasopharyngeal carcinoma. Herein, we report a case of a tumor localized in the left submandibular gland in a 20-year-old male. The tumor mass was surgically excised with the submandibular gland, and the specimen was pathologically confirmed to be lymphoepithelial carcinoma.

Laryngeal lymphoepithelial carcinoma (LEC) is a rare tumor with only 34 cases in the published literature. Epidemiologically, laryngeal LEC is extremely rare in Asian. Originally, LEC is a common type of carcinoma in nasopharynx. Laryngeal LEC resembles nasopharyngeal LEC, except that most cases of laryngeal LEC are not associated with Epstein-Barr virus. We present a case of laryngeal LEC which developed at the left false cord extending to true vocal cord, para-glottic space and pre-epiglottic space. Total laryngectomy with bilateral neck dissection was performed. LEC was reported as biopsy confirmation result. The patient underwent postoperative radiotherapy and showed no evidence of recurrence during follow-up period of 42 months. In consideration that LEC in larynx have not been reported in South Korea yet, we introduce the clinical features and treatment outcomes of laryngeal LEC with literature review.

Neck mass is a common manifestation from head and neck malignancy, most of which come from mucosal squamous cell carcinomas in the upper aero-digestive tract. However, once aspiration cytology suggests atypical malignant cells in the neck mass rather than metastatic squamous cell carcinomas, it is confusing to decide the adequate diagnostic work-ups and treatment planning. Here, we report a 29-year-old woman presenting with a growing neck mass mimicking malignancy of unknown origin, which was finally diagnosed as primary lymphoepithelial carcinoma in the parotid gland with multiple metastases to the lymph nodes. The patient underwent comprehensive neck dissection and total parotidectomy and the adjuvant radiation treatment was given. Our report highlight that the primary salivary gland cancer should be considered as the potential tumor origin in case of malignancy of unknown origin in the head and neck region and neck mass suggestive of atypical carcinomas.

기관지 연관 림프조직 림프종은 비특이적인 호흡기 증상만을 나타내며, 전산화단층촬영에서 세기관지 폐포암, 림프구성 간질성 폐렴등과 뚜렷이 구분이 되지 않는 결절 외 림프종의 일종이다. 저자들은 비특이적인 호흡기 증상만을 나타내는 병변에 대해 침습적인 방법인 경피 미세흡입생검을 시행하여, 원발성 기관지 연관 림프조직 림프종으로 진단하였으며, 병리적 진단이 내려진 상태에서 치료를 목적으로 좌상엽 절제술을 시행하였다. 기관지 연관 림프조직 림프종은 서서히 진행되는 질환으로, 대부분 최종 진단이 늦어지는 경향을 보인다. 국소적 병변일 경우 외과적 수술로 완치가 가능한 질환이므로, 질환이 의심되는 경우 적극적 검사와 치료를 시도하는 것이 중요할 것으로 생각된다.
