The malignant transformation rate of erosive oral lichen planus - a retrospective study

Oral lichen planus is a chronic inflammatory oral condition previously known to have a rate of malignant transformation of around 1%[1]. Additionally, erosive lichen planus, a subtype of lichen planus which is a known risk factor for malignant transformation, has been previously unquantified in a large cohort of patients.We retrospectively assessed 1,920 patients in a single unit observation between 2005 and 2021 who underwent histological analysis for suspected oral lichen planus and followed the progression of their disease to assess the rate of malignant transformation.
