A lymphatic endothelial malignancy, rather than a true sarcoma, composed of multiple red or purple macules, papules, or nodules, that is first apparent on the skin or mucous membranes but may not involve the internal organs. Once a rare disease seen primarily in elderly Mediterranean, African, or Ashkenazi descent, it is the most common cancer related to Aids. In patients with AIDS, KS is believed to be sexually acquired due to acquisition of human herpesvirus 8. When KS is associated with AIDS, it progresses and disseminates rapidly to multiple skin sites as well as the lymph nodes and visceral organs. Cancer that causes patches of abnormal tissue to grow under the skin, in the lining of the mouth, nose, and throat or in other organs. A single infected patch in a skin disease.
Primary or initial lesions include macules, vesicles, blebs or bullae, chancres, pustules, papules, tubercles, wheals, and tumors.
Secondary lesions are the result of primary lesions. They may be crusts, excoriations, fissures, pigmentations, scales, scars, and ulcers.
moisture/fluid within tissues
skin becomes taut, smooth, shiny, and cannot be grasped
appears 1st in dependent areas
press down firmly with thumb or finger [NOT nail] x 5-10 seconds
should return rapidly to usual contour
if not, pitting edema that is graded
[subjectively by examiner]
0 = none
1 = + mild, shallow pit, 2 mm., no visible distortion, disappears rapidly
2 = + moderate, deeper pit, 4 mm., no readily detectable distortion, disappears in 10-15 seconds
3 = + noticeably deep pit, 6 mm., area looks full, may last 1 minute
4 = + deep pit, 8 mm., area grossly distorted, may last 2-5 minutes
Ordinary swelling around the eyes because of an excessive accumulation of fluids in surrounding skin tissue. Because the skin around the eyes is the thinnest skin in the body, swelling and discoloration can be quite prominent. Fluid accumulate to form puffy eyes because edema around the eyes generally results from a variety of factors, including: Overconsumption of salt, which causes fluid retention, Allergies that can cause inflammation and swelling, Sinus problems, Dehydration, Fatigue and lack of sleep, Stress, Crying, Aging, Inherited facial features a wound, injury, or pathologic change in body tissue. 2. Any visible local abnormality of the tissues of the skin, such as a wound, sore, rash, or boil. A lesion may be described as benign, cancerous, gross, occult, or primary.
