Crocker in 1885 is mentioned in his work on “Diseases of the Skin.” I n 1886 and 1889 a number of cases were published independently by Colcott Fox. In 1889 the anatomical seat of the condition was recognized by Mibelli, and further careful and minute obsermtions were added by Pringle in 1891. Since this time many cases have been reported by Dubreuilh, Tommasoli, Thibierge, Audry, Joseph, Fordyce, t and others.

The disease may be described as a multiple capillary angeiectasis, tending to the formation of small tnmour-like prominences under the epidermis. It is almost invariably locdised to the hands or feet, or both, but occasionally invading other parts of the body. In the hands and feet it is nearly always associated with a tendency to chilblains, and sometimes with more or less local asphyxia, and the superjacent epidermis undergoes a verrucose thickening (whence the name “keratoma”), but the cuticular hypertrophy is absent when the growths affect other parts of the body, and is, therefore, not an essential part of the complaint. It appears to be equally common in
