clear cell

(redirected from Light Cell)

clear cell

1. a cell in which the cytoplasm appears empty with the light microscope, as occurs in certain secretory cells of eccrine sweat glands and in the parathyroid glands when the glycogen is unstained;
2. any cell, particularly a neoplastic one, containing abundant glycogen or other material that is not stained by hematoxylin or eosin, so that the cell cytoplasm is very pale in routinely stained sections.

n.
A cell, especially a neoplastic one, containing abundant glycogen or other material that is not stained by hematoxylin or eosin, so that the cytoplasm appears clear histologically.

clear cell

Etymology: L, clarus + cella, storeroom
1 a type of cell found in the parathyroid gland that does not take on a color with the ordinary tissue stains used for microscopic examination.
2 the principal cell of most renal cell carcinomas and occasionally of ovarian and parathyroid tumors.
3 a specific type of epidermal cell, probably of neural origin, that has a dark-staining nucleus but clear cytoplasm with hematoxylin and eosin stain.
A finely vacuolated, cholesterol-filled cell with central dark nuclei, which is arranged in clusters and located in the midzone or zona fasciculata of the adrenal cortex. Clear cells are the major reservoir for glucocorticoid and sex hormone production when the adrenal gland is stressed
