Xerosis

 

dryness of the skin caused by a decrease in the secretion of cutaneous sebum. It is found as a symptom in pellagra, hypovitaminosis A, dehydration of the body, and certain dermatoses. Primary xerosis is found in ectodermal dysplasia, a congenital anomaly in which there occurs an underdevelopment or complete aplasia of the sebaceous-follicular apparatus. A mild form of ichthyosis is sometimes called xerosis.
