GRINSPAN Syndrome
Pronunciation: GRIN-span SIN-drohm
A controversial clinical triad comprising oral lichen planus, diabetes mellitus, and arterial hypertension, now considered by many authorities to represent a drug-induced lichenoid reaction rather than a true syndrome.
Full Definition
Grinspan syndrome was described in 1963 as the co-occurrence of oral lichen planus, diabetes mellitus, and hypertension in the same patient. Subsequent evidence has suggested that hypoglycaemic agents and antihypertensives—both commonly prescribed in this patient group—may independently cause lichenoid drug reactions that mimic oral lichen planus, casting doubt on the syndrome's existence as a distinct entity. The term remains in the literature and in examination contexts, so editors working in oral medicine must be familiar with it. Capitalise 'Grinspan' as an eponymous term; 'syndrome' is written in lower case per standard medical style. Editors should be alert to authors conflating lichenoid drug reactions with genuine oral lichen planus.
Usage
Usage note: Capitalise 'Grinspan'; lowercase 'syndrome'. Some journals retain the possessive 'Grinspan's'—check house style. Authors should qualify whether they accept or dispute the syndrome's validity, as it is contested.
In Context
