AB  - A 25-year-old female presented with worsening right fl ank 
pain and a 9 year history of a slow growing 4 centimeter 
calcifi ed renal mass. The lesion was resected by laparoscopic 
partial nephrectomy revealing a mixed epithelial and 
stromal tumor (MEST). This tumor has unusual features 
including the extensive amount of dystrophic calcifi cation 
and the young age at presentation. Herein, we present a 
focused review of the literature regarding MESTs, as well 
as a discussion of calcifi ed renal mass management. We 
conclude that laparoscopy may be utilized to safely perform 
nephron sparing surgery for select, calcifi ed renal masses.
