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

如果白斑表面变得凹，便称之为结节状黏膜白斑；如果白斑的形状像，则称其为状黏膜白斑。

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.

增生性状白斑成一种特殊的鳞状细胞癌，即状癌，有时也叫作“鼻烟”癌，因为这在鼻烟和其它形式的嚼烟使用者中更常见。
