Abstract

Metastatic lesion of the pancreas is an extremely rare disease, which occupies 2-5% of all pancreatic tumors, and these figures rise to 11% according to autopsies of patients with malignant tumors. Metastatic lesion of the pancreas from primary renal cancer occurs most often (65-74%).
The purpose of the study Differential diagnosis of metastatic lesions of the pancreas
Materials and methods 6 patients with histologically confirmed diagnosis - metastatic renal cell cancer in the pancreas were treated in the period from 2009 to 2013 in " A.V. Vishnevsky Institute of Surgery. Nephrectomy in history was performed in 4 (66.7%) patients in the period from 4 to 16 years. Tumor of the left kidney in conjunction with metastatic pancreatic cancer was detected in 2 (33.3%) patients.
Results and their discussion Solitary metastases were detected in 4 (66.7%) patients. Tumors were located in the head of the pancreas in 3 patients, in the body - in 1. Multiple multifocal lesion of the pancreas was in 2 (33.3%) patients. Dimensions secondary structures ranged from 10 mm to 56 mm.
The most informative diagnostic method in detecting of focal lesions of the pancreas is computed tomography with bolus contrast enhancement . Significant difficulties for interpretation are small tumors that are similar in structure to hormonally active neuroendocrine neoplasm.
Conclusion Revealed solitary or multiple focal disease of the pancreas in patients after nephrectomy for renal cell carcinoma should be regarded primarily as secondary.
