[A case report of 3 patients treated at home with ulcers in the lower extremities, illustrating the difficulty in differential diagnosis between ASO and pressure sores].

It is difficult to diagnostically differentiate pressure sores and cutaneous ulcers that occur at the tip of an appendicular. There are many ways to treat them based on the cause of the problems. However, an inadequate treatment had resulted in limb amputation cases. We report 3 cases performed by a lap treatment for lower extremities ulcers of which occurred at their homes, and that resulted in abscission because their cutaneous ulcers have not improved. The lap therapy was performed due to the fact that these cases involved elderly patients who are inactive and have complications with diabetes mellitus causing comparatively easy pressure sores. However, all three cases were complications seen in arterial sclerosis obliterans of both lower extremities caused by a blood flow disorder of an inferior limb resulting in a pathologic body. Therefore, it was thought that the efficacy of lap therapy could not be indicated. As a result, abscission of the lesion was accomplished. In conclusion, a lap treatment requires careful observation at the beginning and during the treatment of cutaneous ulcers.
