This very rare condition comprises bean-sized, white or bluish-white, round, circular or oval and flattened elevations. Because they can usually be pushed below the level of the cutaneous surface leaving small temporary pits, they have been described as elastic, hollow, bladder-like tumors. Though they seldom actually disappear, involution makes them more flaccid, slightly atrophic with pin-point, scar-like depressions or minute striation on the surface. In the illustration above, the scar-like depressions will be plainly seen. These tumors usually affect the shoulders, trunk and thighs, causing no subjective sensations. They are relatively few at the onset but more develop from time to time.
Fig. 121. – Multiple benign tumor-like new-growths on the back of a middle-aged man. These flattened, oval tumors present minute, scar-like depressions. Some of the lesions were temporarily removed by solidified carbon dioxid. The X-rays were ineffectual.
Etiology and Pathology. – There is no known cause. Fortunately the general health is not affected. Pathological findings show passive retraction or atrophy of the elastic tissue.
Prognosis and Treatment. – There is little hope of disappearance and nothing may be expected of treatment. A case of my own was not benefited by the X-rays, but some few lesions were temporarily removed by solidified carbon dioxid.
