The tumor was diagnosed histologically as an atypical carcinoid, with negative reaction to Grimelius staining and immunohistologically positive for neuron-specific enolase. Electronmicroscopy of the tumor cells revealed a few neurosecretory granules in the cytoplasm. For metastatic liver tumors, the patient was treated with hepatic arterial infusion of 5-FU. Adriamycin, Mitomycin C. She is alive 2 years and 5 months after the operation although hepatic metastases have been developed.
