Diagnosis:
Venous lake
Venous lakes are fairly common vascular ectasias presenting on sun damaged skin of the elderly, showing a predilection for the lip.
Lesions may be multiple and measure up to 1 cm in diameter.
The pathogenesis may be due to possible defective stromal support.
Microscopic features: dilated and congested veins in the superficial dermis. No evidence of vascular proliferation.
