Biology:Oncocyte
From HandWiki
Short description: Epithelial cell
Cytopathology of Warthin's tumor, with typical cellular features (and a relatively uncommon binucleated cell).[1] Pap stain. The relatively large size of the oncocytes is seen when comparing to the lymphocyte.
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.
Other names
Also known as:
- Hürthle cell (thyroid gland only)
- Oxyphilic cell
- Askanazy cell
- Apocrine metaplasia (breast gland only).
- Oncocytic cell
Etymology
Derived from the Greek root onco-, which means mass, bulk.
