title: A single-centre experience with tumour tract seeding associated with needle manipulation of renal cell carcinomas.
abstract: With the rise in detection of incidental renal masses on imaging, there has been a commensurate rise in the use of percutaneous biopsies for evaluation of these tumours. Tumour tract seeding had previously been one of the most feared complications of percutaneous biopsy of renal cell carcinoma (RCC). Recently, less emphasis has been placed on this complication, with the assertion that it has only been reported eight times in literature, and thus must be exceedingly rare. However, we report two cases of tumour tract seeding associated with percutaneous biopsy and treatment of RCC over a short time period at a single institution. This report challenges the current extremely low estimates of the frequency of this complication and calls for a more realistic assessment.
