Venous Lakes

Venous Lakes

A venous lake is a type of vascular malformation that commonly occurs on the lips. Venous lakes look like a dome shaped lump that results from a collection of enlarged veins under the skin. They are typically dark purple or blue in appearance. Venous lakes are typically painless. However, if the venous lake is large and raised it can become irritated, itchy, and sore. Venous lakes can bleed easily if traumatized. You are more likely to have a venous lake if:

• 
  It is a soft, compressible dark blue bump
• 
  It is on your lip, especially your lower lip
• 
  You have a history of long-term sun exposure
• 
  Are over 50 years of age

Venous lakes are harmless and do not present cause for concern. They can however mimic other conditions, such as skin cancer. It is important to have your venous lake evaluated by a qualified health professional, especially if there is any concern about it looking abnormal.
