Abstract
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.Keywords
