Abstract:
We report a unique case for a 1.5 cm Chromophobe Renal Cell Carcinoma (ChRCC) tumor recurrence on the posterior abdominal wall along the renal tumor biopsy tract. This case presented on follow up at 4.5 years after radical nephrectomy T1bN0M0. Pathology was confirmed to be a chRCC with later excision of the mass. We believe the recurrence in this case is due to tumor seeding after multiple Renal Tumor biopsies (RTB) performed before surgery, as the tumor was located along the RTB tract.
