AI Article Synopsis

  • Renal oncocytosis is a rare condition that leads to multiple kidney tumors.
  • It can present as distinct masses on imaging, specifically CT and MR scans, where one mass is usually more prominent.
  • This case highlights a unique combination of renal oncocytosis with chromophobe renal cell carcinoma and includes a review of related literature.

Article Abstract

Renal oncocytosis is a very rare cause of multiple renal masses. Imaging features of renal oncocytosis and combined tumors have rarely been reported. Here, we describe a case of unilateral left renal oncocytosis and a combined hybrid tumor between chromophobe renal cell carcinoma and oncocytoma, which were depicted on CT and MR imaging as multiple enhancing solid masses with one dominant mass. Additionally, we reviewed the literature.

Article Synopsis
  • * A case was reported involving an unusual tumor located between the duodenum and pancreas that couldn’t be classified with known cancers despite thorough testing.
  • * This tumor showed characteristics suggesting it was caused by a loss of the FLCN gene, marking it as the first known extrarenal tumor linked to BHD associated with this genetic mutation.

N-Nitrosomorpholine-induced oncocytic transformation in rat endocrine organs.

Eur J Med Res

Department of Endocrinology and Metabolism, Faculty of Medicine, Kocaeli University, Kocaeli, Turkey.

Background: N-Nitrosomorpholine (NMO) is one of the most common N-nitroso compounds. An oncocytic transformation has been demonstrated in renal tubules of NMO-treated rats. In our study, we aimed to investigate the potential transformation of oncocytic cells in 6 endocrine organs, i.

Birt-Hogg-Dubé (BHD) syndrome is associated with an increased risk of multifocal renal tumors, including hybrid oncocytic tumor (HOT) and chromophobe renal cell carcinoma (chRCC). HOT exhibits heterogenous histologic features overlapping with chRCC and benign renal oncocytoma, posing challenges in diagnosis of HOT and renal tumor entities resembling HOT. In this study, we performed integrative analysis of bulk and single-cell RNA sequencing data from renal tumors and normal kidney tissues, and nominated candidate biomarkers of HOT, L1CAM, and LINC01187 , which are also lineage-specific markers labeling the principal cell and intercalated cell lineages of the distal nephron, respectively.

99m Tc-MIBI SPECT/CT in a Case of Renal Oncocytosis.

Clin Nucl Med

September 2023

Urology, Changhai Hospital, Naval Medical University, Shanghai, China.

Renal oncocytosis is a very rare oncologically indolent form of renal neoplasia characterized by diffuse involvement of renal parenchyma by numerous oncocytic nodules. We describe contrast-enhanced CT and 99m Tc-MIBI SPECT/CT findings in a patient with renal oncocytosis presenting with metachronous bilateral renal tumors. Contrast-enhanced CT showed numerous tumors ranging from several millimeters up to 3.

To explore clinicopathological features of low-grade oncocytic tumor (LOT) of the kidney and to analyze its relationship to hybrid oncocytic/chromophobe tumor (HOCT) of the kidney, renal oncocytoma (RO), and chromophobe renal cell carcinoma (chRCC). Seven LOTs were identified from the pathologic archives of two hospitals, including Xiangya Hospital (5 cases) and the Second Xiangya Hospital (2 cases) of Central South University between 2012 and 2019. Clinical data of the LOTs were collected.
