Squamous cell carcinoma arising from a recurrent oral lichen planus lesion on the radial forearm flap: first report in the English-language literature

Abstract

neck was 7.2 mm (SD 6.54). Other poor prognostic factors such as non-cohesive invasion, lymphovascular and perineural invasion were more frequently seen in association with positive nodes. In accordance with published literature, we found a positive correlation between increasing depth and nodal metastases (p= 0.031 for tumours above 3 mm depth). However, a proportion was associated with more superficially invasive tumours and there appear to be multiple variables associated with positive nodes. In light of this we would suggest the consideration of a prophylactic functional neck dissection in patients with tumours less than 3 mm in thickness.
