Abstract

Introduction: Primary hepatic neuroendocrine tumor (PHNET) is a rare entity comprising 0.3% of all neuroendocrine tumors. Tumors coexisting with granulomas are occasionally noted with malignancies in the lymph nodes draining the tumor or within the primary tumor itself. Tumor-related sarcoid reactions are noted only in carcinomas and its association with a NET has been extremely rare.
Case Presentation: We report a case of PHNET in a 63-year male who presented with various comorbidities who was incidentally detected with a liver space-occupying lesion (SOL). Contrast enhanced CT scan of the abdomen revealed a well-defined exophytic mass in the liver involving segment 6. Subsequently, 68Ga DOTANOC PET/CT scanning revealed somatostatin receptor-expressing well-defined lesion measuring 5.1 x 5.0 cm in segment 6 (SUV MAX 19). A diagnosis of either a primary or a metastatic neuroendocrine tumor was made and non-anatomical wedge resection of the tumor was done with a detailed exploration of the abdominal cavity to look for a primary focus that did not reveal any other lesion or mass. Histologically, the tumor was confirmed to be a Neuroendocrine Tumor along with the presence of tumor-related sarcoid like granulomas in the adjoining hepatic parenchyma.
Conclusion: Diagnosis of a PHNET requires a combination of a negative abdominal survey at the time of the operative procedure, pathologic evaluation of specimen, and a negative imaging workup for extrahepatic NET in both the pre and postoperative settings.
