Verrucous Carcinoma
Pronunciation: veh-ROO-kus KAR-sih-NOH-muh
A low-grade, exophytic variant of oral squamous cell carcinoma with a warty, cauliflower-like surface and pushing rather than infiltrating margins, strongly associated with tobacco use.
Full Definition
Verrucous carcinoma (VC), also known by the eponym Ackermann's tumour, is a well-differentiated squamous cell carcinoma variant characterised by slow growth, a verrucous or papillary exophytic surface, and histologically pushing rather than infiltrating deep margins with minimal cytological atypia. Despite its relatively indolent behaviour, it is locally destructive and can invade bone. Editors should note that 'verrucous hyperplasia' is a distinct and separate entity that may be confused with verrucous carcinoma both clinically and in the literature; the distinction is histopathological. The term should not be abbreviated to 'VC' without prior definition in formal documents.
Usage
Usage note: Do not confuse with verrucous hyperplasia, which lacks the pushing deep margin and is considered a potentially malignant disorder rather than a carcinoma. Always verify usage in context of histopathological confirmation.
