oncocytosis: CT findings with histopathologic correlation.
Emerging entities in renal cell neoplasia: thyroid-like follicular renal cell carcinoma and multifocal oncocytoma-like tumours associated with
oncocytosis. Pathology.
The World Health Organization (2005) classified oncocytic lesions into three distinct categories of
oncocytosis, oncocytoma, and oncocytic carcinoma.

Hybrid oncocytoma/chromophobe tumour/renal cell carcinoma is rare kidney tumour, which can be associated with renal
oncocytosis and Birt-Hogg-Dube syndrome; rare sporadic HOCT were also described.
A case of acquired renal cystic disease (ACDK) with
oncocytosis, a dominant nodule (oncocytoma), multiple adenomas and a microscopic papillary renal cell carcinoma associated with crescentic glomerulonephritis.
In this regard, Brandwein and Huvos (1) found a history of radiation exposure in some of their cases, and Becker et al (14) described an age-dependent intracellular metabolic defect associated with mitochon driopathy as an explanation for the development of
oncocytosis in 2 of their cases.
(26,27) This syndrome can manifest with multifocal oncocytomas (
oncocytosis) and chRCC and should be suggested by a pathologist when more than one lesion is present unilaterally or bilaterally.
The occurrence of oncocytic cells in salivary glands can be categorized as oncocytic metaplasia, nodular or diffuse
oncocytosis, and oncocytoma.
(1) These tumors are classified as one of three types: diffuse
oncocytosis, focal adenomatous oncocvtic hyperplasia, and oncocytoma.
In the first large series on hybrid tumors, Tickoo et al (13) reported on a group of patients with renal
oncocytosis, some of whom developed tumors with hybrid morphologies.
