caption_attribution_description: English: High magnification micrograph of a renal oncocytoma. H&amp;E stain. The tumour cells (left of the image) are arranged in nests, have slightly enlarged nuclei and have a more eosinophilic (darker pink) cytoplasm than the normal kidney - renal tubules (right of image). On electronmicroscopy, oncocytomas have abundant mitochondria. See also Image:Renal_oncocytoma3.jpg - intermediate magnification. Image:Renal_oncocytoma4.jpg - low magnification.
context_page_description: An oncocyte is an epithelial cell characterized by an excessive number of mitochondria, resulting in an abundant acidophilic, granular cytoplasm. Oncocytes can be benign or malignant.
