Female, aged forty-five. The eruption began four years ago in a pigmented spot—a mole or “liver spot,” according to the patient—in the center of the forehead. This became irritated and rough, forming a scab, which was picked off and a strong solution of carbolic applied, but it did not heal. It continually formed a scab which was always picked off, the original area extending all the time. At present there is an ulcerating scabbed patch covering one-half to one inch in the center of the forehead, the edge of the ulcer being hard and raised, and rather characteristic. Shortly after the appearance of this lesion two other superficial crusted patches appeared, one on the left temple, the other on the cheek in front of the upper part of the left ear. These have been curetted, and at present appear as superficial, scaly, red patches, with little evidence of epithelioma. For the past year or so a fourth small circular patch one-quarter of an inch in diameter has been present on the right side of the neck just beneath the lower border of the inferior maxilla toward the front. With the magnifying glass the patch has a depressed center, and a raised, pearly, ring-shaped border, characteristic of the superficial type of the disease.
