Granulomatous
Pronunciation: gran-yoo-LOH-mah-tus
Relating to or characterised by the formation of granulomas — discrete clusters of epithelioid macrophages representing a chronic inflammatory response in the skin or other tissues.
Full Definition
The adjective 'granulomatous' describes histopathological or clinical patterns defined by granuloma formation: organised aggregates of epithelioid macrophages, often accompanied by multinucleated giant cells, lymphocytes, and variable necrosis. In dermatology, granulomatous inflammation underlies diverse conditions including sarcoidosis, granuloma annulare, necrobiosis lipoidica, leprosy, and foreign-body reactions. Editors must render the term correctly (not 'granulomateous' or 'granulomatus') and be aware that 'granulomatous' is an adjective requiring a modified noun (e.g., granulomatous dermatitis), not a standalone noun. It should not be confused with 'granuloma,' the noun describing the actual cellular structure.
Usage
Usage note: Frequently misspelled as 'granulomatus' or 'granulomateous'; flag all variants. Always used as an adjective; do not substitute for the noun 'granuloma.'
