SynopsisA venous lake is a dilation of venules. It is a common lesion, usually manifesting as an asymptomatic dark blue to violaceous papule on the ear or lip of an elderly person. Venous lakes are thought to result from sun damage, which weakens the vascular adventitia and permits dilation of superficial venous structures. 95% of venous lakes occur in men.
Once a lesion has been traumatized, there may be bleeding or tenderness. Venous lakes are of little clinical concern save for their cosmetic appearance and the resemblance they bear to malignant lesions.
