We aimed to present two cases in which grade I neuroendocrine tumors were incidentally detected during our twelve-year living donor hepatectomy experience.
Intraoperative appearance of the lesions of both patients was compatible with benign disease.
Differential diagnosis of the first case included calcified nodule, benign intestinal tumor, and early stage malignant tumor. Differential diagnosis of the second case includes acute appendicitis, mucocele, and carcinoid tumor
No abnormal findings were detected in preoperative biochemical blood tests in both living liver donor candidates.
No abnormal findings were detected in preoperative radiological examinations in both living liver donor candidates.
The immunohistochemical examinations of the specimens of both patients were reported as grade I neuroendocrine tumor.
While a wedge resection with primary intestinal anastomosis was performed in the first case, simple appendectomy was performed in the second case.
To our knowledge, no publication other than our study has ever reported unusual findings, such as cancer, detected incidentally during a living donor hepatectomy procedure.
Even if patients undergoing living donor hepatectomy are healthy individuals, the whole abdominal cavity should be gently palpated and all findings recorded after completing laparotomy. Suspected masses or lesions should be confirmed by frozen section examination.
