Hello,
I see you are asking "What is dyskeratosis follicularis vegetans?"
Keratosis follicularis, also known as Darier disease, is a rare, genetic skin disorder. Affected individuals develop skin lesions that consist of thickened, rough bumps (papules) or plaques that may also be greasy or have a brown or yellow crust. These hardened, scaly lesions are progressive and may gradually grow bigger or spread. The nails and mucous membranes are also affected in most cases. Individuals may have periods of time when signs improve (remission), but the lesions usually recur (relapse).
