title: Synchronous transperitoneal laparoscopic resection of right retroperitoneal schwannoma and left kidney monotypic PEComa in the presence of a duplicated inferior vena cava (IVC).
abstract: A 21-year-old female presented with a retroperitoneal mass in the right side and a centrally located renal mass in the left kidney with an aberrant vascular anatomy of a double inferior vena cava. The 2 tumors were radically excised by a transperitoneal laparoscopic approach in one session. Histopathologic examination revealed the right retroperitoneal lesion to be a schwannoma and the renal mass to be a cluster of monotypic neoplasms with perivascular epithelioid cell differentiation (PEComas). The latter is a rare tumor.
