Abstract
BACKGROUND
Combined tumors comprising large-cell neuroendocrine carcinoma and hepatocellular carcinoma have been rarely reported in the literature.
CASE SUMMARY
We report a case of a 73-year-old woman with chronic hepatitis B suspected to have a malignant hepatic mass (segment 3; size, 4.5 cm) and lymph node metastasis based on computed tomography and magnetic resonance imaging. Despite being Child-Pugh class A, esophageal varices were present. She underwent left lateral sectionectomy and lymph node dissection. Pathological examination revealed a collision tumor consisting of large-cell neuroendocrine (90%) and hepatocellular (10%) carcinomas. The combined carcinoma had metastasized to one of the three lymph nodes excised. The patient recovered without any postoperative complications and was discharged in good condition on postoperative day 13. Adjuvant chemotherapy was not performed. No recurrence occurred during a follow-up period of 24 mo.
CONCLUSION
To improve the therapeutic management of combined tumors in the liver, it is necessary to discuss each clinical experience and consider an appropriate method for the preoperative diagnosis and treatment.
Core Tip: Collision tumors originating from the liver are extremely rare. No rational surgical strategies for these tumors have been reported because of their rarity, the shortness of knowledge of predictive prognostic factors, the inability to identify progression, and the limited understanding of the biohistology of these lesions. However, complete resection of a resectable locoregional neuroendocrine tumor has excellent outcomes. Because of their rarity, there are no proper guidelines for adjuvant treatment. It is necessary to discuss each clinical experience and consider an appropriate method for the preoperative diagnosis and treatment.
