A patient with carcinoid tumor of the head of pancreas and carcinoid syndrome presented without liver metastasis. The patient had retroperitoneal lymphadenopathy. He had symptoms of flushing, diarrhea and abdominal pain. 5-Hydroxyindoleacetic acid (5-HIAA) was elevated. Absence of liver metastasis was documented not only by the negative computed tomography (CT) scan and liver/spleen scan, but also by autopsy. Except for carcinoid arising from ovary, testis, or bronchi, the other carcinoid tumors rarely cause carcinoid syndrome without liver metastasis. The literature was reviewed, and the findings are presented.
