Evaluation of Cases Presenting with a Liver Mass

INTRODUCTION: The diagnostic approach to liver masses is important in treatment planning. The aim of this study was to determine the histopathological diagnoses of patients presenting with liver masses and the distribution of organs from which metastases originated.
METHODS: A retrospective evaluation was performed on 106 patients who presented to the Internal Medicine Clinics between 2016 and 2020, were diagnosed with liver masses, and underwent biopsy.
RESULTS: Hepatocellular carcinoma was diagnosed in 9 patients (8.4%), while metastasis was detected in 97 patients (91.6%). Benign pathology was detected in 2 patients (1.8%). Among the metastatic patients, 19 (17.9%) had pancreatic cancer, 15 (14.2%) had colorectal cancer, 14 (13.2%) had lung cancer, 9 (8.2%) had breast cancer, and 9 (8.2%) had gastrointestinal stromal tumors.

When histological diagnoses were evaluated, adenocarcinoma metastasis was detected in 65 patients (61.6%), neuroendocrine tumor in 12 patients (11.2%), hepatocellular carcinoma in 9 patients (8.4%), and 15 patients (14.2%) had unknown primary tumors.


DISCUSSION AND CONCLUSION: The majority of liver masses are composed of metastases. Hepatocellular carcinoma is the most common primary tumor of the liver. The diagnostic evaluation of patients with liver masses is important for treatment purposes
