[Oncocytoma of the pancreas. A case report].
For the first time in the bulgarian literature a case with pancreatic oncocytoma is described, initially diagnosed as carcinoma. The patient survived for 13 years being nowadays in perfect condition.
Background ::: Spontaneously metastatic xenograft models of cancer are infrequent and the few that exist are resource intensive. In xenografts, caliper measurements can be used to determine primary tumor burden and response to therapy but in metastatic disease models determination of the presence of metastatic disease, metastatic burden, and response to therapy are difficult, often requiring serial necropsy. In this study we characterized the development of visceral metastases in a patient derived xenograft model (PDXM) using in vivo imaging.
