\u2022 It becomes especially common in persons who are older than 65 years of age (FIG. 16.1). Pathogenesis \u2022 The reasons why the skin becomes\u2014or appears to become\u2014dry are not well understood. It has been proposed that xerosis may be secondary to diminished production of sebum (asteatosis), as well as to reduced eccrine gland activity.<\/p>\n

However, other biochemical factors related to aging skin have also been implicated. \u2022 Popular folklore and the lay literature often blame xerosis on inadequate water ingestion, but there is no scienti\ufb01c basis for this claim. Asteatotic Eczema See also FIGURE 2.52. \u2022 Asteatotic eczema (winter eczema) is caused by a relative loss of water from the skin through evaporation, a lack of normal desquamation, and, possibly, a decline in the pro- duction of sebum (the skin\u2019s natural lubricant and sealant).<\/p>\n

\u2022 Most often seen on the shins, with seasonal recurrences dur- ing the winter months, this form of eczema is a common, sometimes pruritic, low-grade dermatitis. Early on, the affected skin feels and looks dry (FIG. 16.2); later, an in\ufb02am- matory dermatitis may evolve. 16.1 Xerosis. Dry skin tends to be most apparent on the hands and lower legs.<\/p>\n

This elderly patient\u2019s legs are dry and scaly. 16.2 Asteatotic eczema. Xerosis and subtle changes con- sisting of exaggerated skin markings are seen in this patient. Chapter 16 \u2022 Xerosis: The \u201cDry\u201d Patient \u2022 Occurring exclusively in adults, lesions most commonly appear on the shins, arms, hands, and trunk (see Chapter 2, \u201cEczema\u201d). Because the eruption often resembles the sur- face of a cracked porcelain vase, it is often referred to as erythema craquel\u00e9. It is also likened to the appearance of a dry riverbed (FIG.<\/p>\n

16.3). \u2022 A clinical variant consists of small, square, scaly plaques that are often mistaken for tinea corporis (ringworm) or pso- riasis and treated as such (FIG. 16.4).<\/p>\n
