A 50-year-old female, who had been on maintenance hemodialysis for 22 years, consulted our clinic because of a left renal mass detected incidentally by ultrasonography. Computed tomography (CT) demonstrated a solid hypervascular mass, suggesting a renal cell carcinoma (RCC), in the left atrophic kidney. Left hand-assisted laparoscopic nephrectomy (HALN) was performed. The histopathological diagnosis was renal oncocytomatosis. Renal oncocytomatosis in a long-term hemodialysis patient is extremely rare. We report the first case of renal oncocytomatosis in a long-term hemodialysis patient treated with hand-assisted laparoscopic nephrectomy.
An α-fetoprotein-producing transitional cell carcinoma of the renal pelvis is extremely rare. To our knowledge, this has not been reported previously. We present the first case of an α-fetoproteinproducing transitional cell carcinoma of the renal pelvis in a 70-year-old female.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
