Needle tract seeding following percutaneous biopsy of renal cell carcinoma.

Needle tract seeding following percutaneous biopsy of renal cell carcinoma. Korean J Urol. 2015 Sep;56(9):666-9 Authors: Chang DT, Sur H, Lozinskiy M, Wallace DM Abstract A 66-year-old man underwent computed tomography-guided needle biopsy of a suspicious renal mass. Two months later he underwent partial nephrectomy. Histology revealed a 30-mm clear cell renal cell carcinoma, up to Fuhrman grade 3. An area of the capsule was interrupted, which corresponded to a hemorrhagic area on the cortical surface. Under microscopy, this area showed a tongue of tumor tissue protruding through the renal capsule. A tumor deposit was found in the perinephric fat. These features suggest that tumor seeding may have occurred during the needle biopsy. PMID: 26366280 [PubMed - in process]
