Increased salivary aldehyde dehydrogenase 1 in non-reticular oral lichen planus

An. bras. dermatol; 92 (2), 2017
Abstract: Background: Oral lichen planus is a potentially malignant disorder. One of the malignant transformation markers is cancer stem cells. One of the proposed marker for the detection of cancer stem cells's in head and neck cancer is aldehyde dehydrogenase. Recently it is shown that aldehyde dehydr...
