What is the name of the inflammatory condition that causes cracks, crusting and scaling at the corners of the mouth due to vitamin B 2 deficiency?

Explanation

Cheilosis refers to inflamed, cracked lips and can accompany riboflavin deficiency. Lesions at the mouth corners are also called angular stomatitis or angular cheilitis. Such lesions have other possible causes, so this sign alone is not a diagnosis of B 2 deficiency.
