Summary: | Lymphoepithelioma-like carcinoma (LELC), a rare and unique variant of liver cancer, can be divided into lymphoepithelioma-like hepatocellular carcinoma and lymphoepithelioma-like intrahepatic cholangiocarcinoma. Dense lymphocytic infiltration is its characteristic pathological feature. In recent years, the number of reported cases of this type has increased each year. Studies have shown that lymphoepithelioma-like cholangiocarcinoma occurs more frequently in Asian women; LELC is associated with Epstein-Barr virus infection of liver cells of epithelial origin. Existing research shows that the prognosis of this tumour is good.
A 38-year-old female patient was hospitalized after 3 mo of abdominal pain and nausea. She had been infected with hepatitis B virus more than 10 years prior. The patient was hospitalized on January 21, 2022. Magnetic resonance imaging showed a 36 mm Ă— 28 mm mass under the envelope of the left inner lobe of the liver. No metastasis of lymph nodes or other organs was observed. After left hemihepatectomy, biopsy and immunohistochemistry yielded a final diagnosis of lymphoepithelial hepatocellular carcinoma. After 12 mo of outpatient follow-up and chemotherapy, no tumour metastases were found on the latest computed tomography examination.
Herein, the patient was treated surgically and then followed up as an outpatient for 12 mo. This case will further expand our overall knowledge of the diagnosis and treatment of this rare tumor. |
