A RARE CLINICAL CASE OF MIXED SEROUS NEUROENDOCRINE CYSTIC NEOPLASM OF THE PANCREAS

Background. Serous cystic pancreatic neoplasm is a rare pancreatic tumor, accounting for 1–2 % of all pancreatic tumors. In 2010, mixed serous neuroendocrine cystic neoplasia was included into the classification of the WHO for pancreatic tumors. Only a few cases of this disease have been reported in the literature. Mixed serous neuroendocrine cystic neoplasia is often associated with von Hippel Lindau disease. Most authors recommend surgery as a main treatment of this disease.Case report. We present a case with mixed serous neuroendocrine cystic neoplasia not associated with von Hippel Lindau disease. The patient underwent spleen – preserving distal pancreas resection. The diagnosis was histologically and immunohistochemically verified. There is no evidence of disease recurrence within 10 months after surgery. Conclusion. Histological examination of the resected serous cystadenoms should take into account the possibility of combining this pathology with pancreatic neuroendocrine tumors. For the purpose of verification, the use of immunohistochemical examination is required. Radical surgical resection allows patients with this disease to be cured.
