Abstract

Hepatocellular carcinoma (HCC) accounts for most of the hepatic neoplasms and can also occur in ectopic liver tissue. We present a case of a 55-year-old male complaining of weight loss. The imaging studies reported a 2.9 cm nodule in the pancreatic body, with a neuroendocrine tumor diagnosis by cytology. A corpo-caudal pancreatectomy was performed. Pathology showed a well-differentiated HCC developed in ectopic liver tissue with free margins and no lymph node metastases. HCC presenting in ectopic liver tissue is rare. In this case, the preoperative study did not establish the diagnosis, warranting the need for suspicion of this neoplasm.
