In 1916 Sutton reported two cases of a condition which he considered to be an unusual variety of vitiligo, and he named the disease leukoderma centrifugum acquisitum.1 In one case there was one oval patch, in the exact center of which was a small round elevated brownish maculopapule. It resembled a small pigmented nevus and, according to the statement of the patient, had been there only since the onset of the attack, which dated back three years. There was no hyperpigmented areola surrounding the patch of vitiligo.
The second patient had four lesions which were similar to the one described. Two of the lesions were faint and almost imperceptible; the mother of the patient stated that originally one of these patches was much more distinct but that it had gradually regained some of its color.
On microscopic examination Sutton noted an increase of pigment in the basal layer
