Schweninger and Buzzi,1 in 1891, under the title "Multiple Benign Tumor-Like Growths" described a unique anomaly of the skin.
Crocker2 gave a very good description of this condition, which we cannot improve on. He wrote: "Clinically, the lesions are soft, round or oval projections, from a lentil to a bean in size, more or less white, with a slight blush or slate color in some of them. Most of them are bladder-like, and can be pressed into the skin by the finger, projecting immediately again like a hernia. The larger ones are flattened and slightly puckered, and harder than the smaller, from which they develop. They undergo spontaneous resolution, and leave only flaccid, loose, foveated scars. They appear very gradually and without sensory symptoms on the trunk, shoulders and thighs and ultimately become numerous, as none disappear entirely, and others keep forming."
Further on, Crocker says: "I have
