While the numerous white spots so caused are objectionable, they are better borne by patients than the pigmented appearance. A thorough needling of the spot in this way eventually brings about an improvement, and if, for æsthetic reasons, the patient objects to the unsightliness of the result thus obtained, the white area may be carefully tattooed with an appropriate color to match the rest of the skin of the face or neck.

If the pigmented area is not too large, it can be excised with the knife and the healthy skin be brought together with a fine silk suture, thus leaving a thin linear scar which can be dealt with as the punctate scar area, if desired; the electrolysis being a painful procedure at all times, since sufficient milliampères must be used to cause scar-tissue formation, which is between 20 to 30 milliampères in such cases.

22. The Breaking Down of Tissue and Resultant Abscess Due to the Pressure of the Injected Mass upon the Adjacent Tissue after the Injection Has Become Organized.—The above result is particularly noticeable when the injections have been made into the cheek or the breast. It is understood that the suppurative changes under consideration herein are not attributable to imperfect sterilization of the injected matter, although it is possible, and perhaps is the cause in fifty per cent of the suppurative elimination of the infected mass from the cheek, that a nucleus of infection is carried into the tissues and is held in suspense for a time, because of its imbedment in a neutral media that does not readily permit of bacteriological propagation, but eventually this nucleus must come in contact with tissue which it can affect, and only then may its infection be taken up.

The author believes that such secondary affections are accountable to pressure effects upon the blood vessels or glandular structure, as in the case of breast injections, the new connective tissue causing a lack of nourishment in the part or gland, and a resultant breaking down of the tissue, directly influenced in some instances by external violence.

Tuffier reports the elimination of paraffin injected into the breast several weeks after the injection. If this elimination had been caused by primary infection an acute reaction would have taken place at least within forty-eight hours, ending in abscess shortly after.

A case which came to the author’s attention was that of a lady who had been operated upon for the correction of a saddle nose three months before. The result had been satisfactory. The day previous to consulting the author she had injured her nose in an automobile accident. The nose was much swollen, very painful, and red over the entire upper and middle third. The use of external cold did not relieve the condition much, and on the fourth day the skin broke open at one point, allowing pieces of the paraffin to escape. Immediate relief followed, the wound healed with a marked sinking of the middle third of the nose. After three weeks the nose was again injected with no further untoward symptoms, the result being satisfactory for two years past.

In this case undoubtedly the exciting cause was directly due to violence, which may be the forerunner in many of such cases, but there is a number of such eliminations directly due to a breaking down of the tissue from internal pressure alone.

There is no way to overcome this difficulty, except to await the definite formation of the abscess and then to puncture the skin directly over the soft fluctuating area and to drain the cavity.

Once relieved, the condition quickly subsides, leaving a certain amount of loss of contour, which can, however, be corrected several weeks after by a secondary injection.

When the abscess occurs in the cheek it is not advisable to open interiorly, but to make the puncture through the skin, on account of the danger of infection from the buccal cavity and of the imperfect evacuation thus attained.
