A venous lake is a small dark blue compressible bump in the skin.[1] There is typically just one of them and it is commonly found on sun-exposed surfaces of the lip border, face and ears.[2] It tends to feel soft and can measure 0.2- to 1-cm.[2] Lesions generally occur among the elderly.[3]
The blue color is of blood.[1] Though these lesions may resemble nodular melanoma, the lack of induration, slow growth, and lightening appearance upon diascopy suggest against it, and indicate a vascular lesion.[4] Additionally, lack of pulsation distinguishes this lesion of the lower lip from a tortuous segment of the inferior labial artery.[5]
Treatment options include light electrocautery, laser ablation, infrared coagulation, radiofrequency ablation injecting it with 1% polidocanol, and cryotherapy.[1]
The term was coined by American physician William Bennett Bean in 1956.[6]
Cause
The cause is unknown; however it is thought to be associated with sun exposure, leading to a dilated blood-filled vascular channel[2] "...lined with a singled layer of flattened endothelial cells and a thin wall of fibrous tissue filled with red blood cells."[4]
Treatment
Treatment options include light electrocautery, laser ablation, infrared coagulation, radiofrequency ablation, injecting it with 1% polidocanol, and cryotherapy.[1]
