A lake on lower lip.

A localized vascular dilatation frequently involving sun-exposed skin is the source of the common vascular tumor known as the venous lake of the lip. Venous lakes are sometimes known as phlebectasias or senile hemangiomas. Deterioration of the connective tissue in the vascular adventitia and dermis plays a pivotal role in the development of the lesion. In older adults, they are frequently placed over the lower lip. It is seen as a smooth-surfaced, round or oval, soft, dark blue-to-dark purple nodule with sharply defined edges. Venous lakes can exhibit cosmetic damage or bleaching following local trauma, despite the fact that they are typically asymptomatic and of varying size. [ABSTRACT FROM AUTHOR]
