ⓘ Venous lake


ⓘ Phlebectases

A venous lake is a generally solitary, soft, compressible, dark blue to violaceous, 0.2- to 1-cm papule commonly found on sun-exposed surfaces of the vermilion border of the lip, face and ears. Lesions generally occur among the elderly.

Although these lesions may resemble Nodular melanoma, the lack of induration, slow growth, and appearance of clarification on diascopy suggest against it, and indicate a vascular lesion. Additionally, lack of pulsation distinguishes this lesion of the lower lip from a tortuous segment of the lower labial artery.
