Congenital defect of the epidermis and true skin is a rarity in pathology. Pastorello speaks of a child which lived for two and a half hours whose hands and feet were entirely destitute of epidermis; the true skin of those parts looked like that of a dead and already putrefying child. Hanks cites the history of a case of antepartum desquamation of the skin in a living fetus. Hochstetter describes a full-term, living male fetus with cutaneous defect on both sides of the abdomen a little above the umbilicus. The placenta and membranes were normal, a fact indicating that the defect was not due to amniotic adhesions; the child had a club-foot on the left side. The mother had a fall three weeks before labor. Abnormal Elasticity of the Skin.--In some instances the skin is affixed so loosely to the underlying tissues and is possessed of so great elasticity that it can be stretched almost to the same extent as India rubber. There have been individuals who could take the skin of the forehead and pull it down over the nose, or raise the skin of the neck over the mouth. They also occasionally have an associate muscular development in the subcutaneous tissues similar to the panniculus adiposus of quadrupeds, giving them preternatural motile power over the skin. The man recently exhibited under the title of the "Elastic-Skin Man" was an example of this anomaly. The first of this class of exhibitionists was seen in Buda-Pesth some years since and possessed great elasticity in the skin of his whole body; even his nose could be stretched. Figure 70 represents a photograph of an exhibitionist named Felix Wehrle, who besides having the power to stretch his skin could readily bend his fingers backward and forward. The photograph was taken in January, 1888. In these congenital cases there is loose attachment of the skin without hypertrophy, to which the term dermatolysis is restricted by Crocker. Job van Meekren, the celebrated Dutch physician of the seventeenth century, states that in 1657 a Spaniard, Georgius Albes, is reported to have been able to draw the skin of the left pectoral region to the left ear, or the skin under the face over the chin to the vertex. The skin over the knee could be extended half a yard, and when it retracted to its normal position it was not in folds. Seiffert examined a case of this nature in a young man of nineteen, and, contrary to Kopp's supposition, found that in some skin from over the left second rib the elastic fibers were quite normal, but there was transformation of the connective tissue of the dermis into an unformed tissue like a myxoma, with total disappearance of the connective-tissue bundles. Laxity of the skin after distention is often seen in multipara, both in the breasts and in the abdominal walls, and also from obesity, but in all such cases the skin falls in folds, and does not have a normal appearance like that of the true "elastic-skin man."
