VENOUS LAKES
Venous lakes are small, dark-blue, slightly elevated, soft lesions that are predominantly localized on the lips (Fig. 106.15), ears, or face of older adults. They can usually be emptied of most of their blood content by persistent pressure. Pathologically, venous lakes represent telangiectasias in the dermis. Either one great, dilated venule or several communicating dilated spaces that contain erythrocytes are seen. Thrombosis is sometimes present. Optional treatment with electrosurgery or a hemoglobin-targeting laser is usually effective.
