Lymphoepithelioma-like carcinoma (LELC) is a non-nasopharyngeal undifferentiated carcinoma with prominent lymphoid infiltration. To our knowledge, only two cases of LELC in the trachea have ever been reported. This tumor has a strong association with the Epstein-Barr virus (EBV), which is especially prevalent in Asians and absent in Caucasians. We report a case of tracheal LELC with EBV-association in a 22-year-old man. The patient was treated with tracheal resection and anastomosis, followed later by adjuvant radiotherapy.

ABSTRACT: Context.-The World Health Organization has recently recognized lymphoepithelioma-like carcinoma, or inflammatory hepatocellular carcinoma, as a variant of hepatocellular carcinoma. Objective.-To identify and characterize the inflammatory hepatocellular carcinomas in our institution from 1988 to the present. Design.-All cases of hepatocellular carcinoma in our institution from 1988 to the present were reviewed and reclassified as lymphoepithelioma-like carcinoma and were studied in comparison to appropriately matched controls. Results.-Among the 8 cases of lymphoepithelioma-like carcinoma identified, the male to female ratio was 1:3, the mean age was 68.5 years (range, 57-78 years), and all of the cases were seen in noncirrhotic livers. The average numbers of lymphocytes were significantly higher in the cases than in the controls. T cells were predominant, with a uniform distribution of CD4 and CD8 positive cells. Cholangiolar differentiation was seen by K19 positivity as focal in 1 case and diffuse in 2 cases. In situ hybridization for Epstein-Barr virus was negative in all of the cases. Diffuse overexpression of p16 (>75% of cells) was seen in 2 cases, both of which were negative for the presence of transcriptionally active human papilloma virus by in situ hybridization. In our series, 3 of 8 cases (37.5%) showed local recurrence, which was similar to the controls (6 of 18; 33%), P > .99. Although the rate of distant metastases was lower among the cases (12.5%) than the controls (22.2%), the difference was not statistically significant (P > .99). Conclusion.-We present the first series of 8 cases of lymphoepithelioma-like carcinoma of the liver occurring in patients without cirrhosis and with a female preponderance and the absence of Epstein-Barr virus. Although clinical outcomes were similar to those of controls in our small series, additional data may be required for confirmation.Archives of pathology & laboratory medicine 04/2014; 138(9).

ABSTRACT: Lymphoepithelioma-like hepatocellular carcinoma is rare, which has been recognized as a variant of hepatocellular carcinoma. Here we report a locally advanced case of lymphoepithelioma-like hepatocellular carcinoma. A 50-year-old man with chronic hepatitis B virus infection presented with a single mass in the liver and two enlarged lymph nodes in retroperitoneum suspected to be hepatocellular carcinoma with lymph node metastasis. After discussion by multidisciplinary team, the patient underwent hepatectomy of VIII segment and dissection of two enlarged lymph nodes. One month after the operation, pre-chemotherapy abdominal computed tomography (CT) showed retroperitoneal enlarged lymph nodes, considered as local recurrence. Therefore, 3 cycles of oxaliplatin and tegafur gimeracil oteracil potassium capsule and 3 cycles of paclitaxel and cisplatin were offered, and post-chemotherapy abdominal CT revealed disease remained stable. The patient has been alive for 6 months since performance of surgery. Our report suggests that even locally advanced lymphoepithelioma-like hepatocellular carcinoma may have a good prognosis and operation and postoperative chemotherapy may benefit the patient.International journal of clinical and experimental pathology 06/2015; 8(3):3282-7. · 1.89 Impact Factor
