Term
abnormal cell mitosis
Definition
incomplete cell division resulting in improper alignment of chromosomes; can create multinucleated giant cells, unequal # nuclei, or distinctly abnormal shapes in metaphase
Term
adeno
Definition
combining form denoting relationship to gland/s
Term
acinar
Definition
any cluster of cells that resembles a many-lobed berry
Term
anisokaryosis
Definition
variation in nuclear size
Term
anisonucleoliosis
Definition
variation in nucleolar shape or size; more significant if variation occurs inside same nucleus
Term

macronucleoli
Definition
increased nucleoli size ( > 5 microns)
Term
multinucleation
Definition
more than 1 nucleus in cell
--increased significance if accompanied by anisokaryosis
--very significant is odd # nuclei within same cell
Term
neoplasia
Definition
any new or abnormal growth; may be benign or malignant
Term
N:C
Definition
ratio of volume of nucleus to volume of cytoplasm

Term
pyogranulomatous
Definition
epithelial-like macrophages with many neutrophils
Term
granulomatous
Definition
predominantly macrophages without many neutrophils
Term
epithelioid cells
Definition
morphologically similar to typical macrophages except cytoplasm contains either no or only small vacuoles
Term
multi-nucleated giant cells
Definition
macrophages with multiple nuclei
Term

Definition
degenerative similar to depletion but implies a decrease in function and form
Term
dehydration
Definition
lack of fluid in cellular and interstitial spaces
Term
