Vacuolization

(Redirected from Vacuolisation)

Definition

noun, plural: vacuolizations

The formation into, or multiplication of, vacuoles; being filled with vacuoles


Supplement

Vacuolization refers to the state or the process of forming vacuoles. The vacuoles may form inside or adjacent to the cells.1 There are many instances in which vacuoles form. One of which is the neurodegenerative diseases in humans and animals caused by prions. One of the histological features of prion diseases (e.g. Creutzfeldt-Jakob syndrome, Gerstmann-Straussler syndrome, kuru, scrapie, fatal familial insomnia, bovine spongiform encephalopathy, transmissible mink encephalopathy, etc.) is vacuolization in the gray matter. Another is the adult-type rhabdomyoma. It is a benign tumor of striated muscle usually in the head and neck region in the adult-type. The pathologic feature presents a solitary, well-demarcated, submucosal nodule. Histologically, cytoplasmic vacuolization occurs often producing a clear cell appearance or a spider cell formation.2
