If it becomes bumpy it's called nodular leukoplakia, and if it becomes wart-like it's called verrucous leukoplakia.

如果白表面变得凹凸不平，便称之结节状黏膜白；如果白状像，则称状黏膜白。

Proliferative verrucous leukoplakia can turn into a particular type of squamous cell cancer called verrucous carcinoma, and it's also sometimes called snuff-dipper's cancer since it is more common among users of snuff and other forms of chewing tobacco.

增生性状白可发展成一种特殊鳞状细胞癌，即状癌，有时也叫作“鼻烟”癌，因这在鼻烟和它式嚼烟使用者中更常见。
