The lesions started on the back of the neck and gradually spread to the abdomen and over the extremities as discrete and grouped papules. The elementary lesion was a papule. In some instances it was covered with a scale and surrounded by a faint areola. The papules increased in size, the centers becoming atrophic and white, and the borders slightly raised.
