  • Perivascular Epithelial Cell (PEComa) Tumors are extremely rare. These tumors are often regarded as low grade Sarcomas and treated as such. We report a case of a 70 year old female with a history of nonspecific complaints and on routine CT scan had bilateral multiple renal masses with no other extra renal disease. The largest mass on the right was 11 cm x 7 cm x 11 cm and the left there were multiple smaller masses. She underwent a right radical nephrectomy that showed a PEComa and an adjacent renal cell carcinoma. Her contralateral kidney was followed for 3 years with no evidence of growth or metastasis.
