Definition

Noun: The condition or state of possessing an abnormally high number of cells within a tissue or organ.

Usage

"Hypercellularity" is a medical and pathological term used to describe an abnormal increase in cellular density. It is typically observed through microscopic examination of tissue samples (biopsies). This state can indicate various conditions, such as inflammation, infection, or neoplasia (abnormal growths like tumors).

Examples

• The bone marrow biopsy revealed significant hypercellularity, prompting further tests.
• Hypercellularity in the lymph node was a key diagnostic feature.
• The pathologist's report noted focal hypercellularity in the sampled tissue.

Advanced Usage

• Qualitative Description: The term is often modified by adjectives to specify degree or pattern (e.g., , , ).
• Comparative Context: It is frequently used in contrast to normal cellularity or hypocellularity (abnormally low cell count).

• Hypercellular (adjective): Describing a tissue that exhibits hypercellularity.

• Acellularity (noun): The state of being without cells.
