The dilated channels have very thin walls that are lined by a single layer of flattened endothelium and supported by a thin layer of fibrous connective tissue. Usually, no smooth muscle or elastic tissue is found in the vessel wall. In rare cases, a thin and noncircumferential area suggestive of smooth muscle can be found instead of the fibrous tissue. Solar elastosis and other evidence of sun damage usually are found in the adjacent dermis. Venous lakes are nonproliferative vascular lesions that are not treatable via medical means.
Treatment usually is performed for cosmetic reasons or to alleviate recurrent bleeding.
Surgical treatment by cryosurgery, electrosurgery, or excision can be successful. All of these approaches are economical modalities. Occasionally, treatment has been complicated by prolonged bleeding, swelling, pain, or scarring. In the past, the use of the argon laser and infrared coagulator required up to 10-14 days for resolution of crusting and eschar formation. There was a marked tendency toward scar formation.
