Venous lake, also called phlebectasis, is a common benign vascular lesion appearing as a dark blue or purple spot on the skin. It typically occurs on sun-exposed areas like the lips, ears, or face. The lesion is soft, compressible, and painless, caused by the dilation of small blood vessels (venules) near the skin’s surface.
This dilation results in blood pooling, giving the characteristic color. While venous lake poses no serious health risks, its appearance may concern some individuals. It is important to note that venous lake is not a form of skin cancer and has no malignant potential.
Venous lake is more prevalent in individuals over 50 years old but can occur in younger people, especially those with a history of sun exposure or a family history of the condition. Although generally harmless, some people may seek treatment for cosmetic reasons. It is advisable to consult a healthcare professional for an accurate diagnosis and appropriate management of venous lake.

Causes of Venous Lake
Sun Exposure and Blood Vessel Damage
Prolonged exposure to ultraviolet (UV) radiation from the sun can weaken the walls of the blood vessels, leading to their dilation and the formation of venous lake.
Genetic Factors
Additionally, genetic factors may also play a role in the development of venous lake, as individuals with a family history of the condition may be more predisposed to developing it themselves.
Trauma and Injury
Another potential cause of venous lake is trauma or injury to the affected area. Physical trauma, such as biting the lip or ear, can lead to damage to the blood vessels and contribute to the development of venous lake. While the exact cause of venous lake may vary from person to person, it is important to take steps to protect the skin from excessive sun exposure and to seek medical attention if any trauma or injury occurs to the skin.
Symptoms of Venous Lake
Venous lake typically presents as a small, dark blue or purple spot on the skin. The lesion is usually soft, compressible, and painless to touch. It may appear as a single spot or multiple spots clustered together.
Venous lake is most commonly found on sun-exposed areas of the body, such as the lips, ears, or face. While venous lake is generally harmless and does not cause any physical discomfort, it can be cosmetically bothersome for some individuals due to its appearance. In some cases, venous lake may bleed or become ulcerated if it is accidentally traumatized or injured.
However, this is rare and does not typically occur without external influence. It is important to monitor any changes in the appearance or behavior of venous lake and seek medical attention if there are any concerns.
Diagnosis of Venous Lake
| Patient | Age | Gender | Location of Venous Lake | Size of Venous Lake | Diagnosis Method |
|---|---|---|---|---|---|
| 1 | 45 | Male | Lip | 5mm | Clinical examination |
| 2 | 60 | Female | Ear | 8mm | Dermoscopy |
| 3 | 55 | Male | Lower lip | 3mm | Biopsy |
Diagnosing venous lake typically involves a physical examination by a healthcare professional. The characteristic appearance of the lesion, along with its location on sun-exposed areas of the body, can often provide enough information for a clinical diagnosis. In some cases, a dermatoscope may be used to examine the lesion more closely and rule out other potential skin conditions.
If there is any uncertainty about the diagnosis, a skin biopsy may be performed to confirm the presence of venous lake. During a skin biopsy, a small sample of tissue from the lesion is removed and examined under a microscope to look for characteristic features of venous lake. This can help rule out other potential causes of the lesion and ensure an accurate diagnosis.
Treatment Options for Venous Lake
While venous lake is generally harmless and does not require treatment, some individuals may seek treatment for cosmetic reasons or if the lesion becomes bothersome. Several treatment options are available for managing venous lake, including laser therapy, cryotherapy, and surgical excision. Laser therapy involves using a focused beam of light to target and destroy the blood vessels causing the venous lake.
This can help reduce the appearance of the lesion and improve its cosmetic appearance. Cryotherapy involves freezing the lesion with liquid nitrogen, causing it to shrink and fade over time. Surgical excision may be considered for larger or more bothersome lesions, where the affected tissue is removed under local anesthesia.
It is important to consult with a healthcare professional to discuss the most appropriate treatment option based on the size, location, and individual preferences for managing venous lake.
Prevention of Venous Lake
Protecting the Skin from Sun Exposure
Preventing venous lake involves taking steps to protect the skin from excessive sun exposure and minimizing trauma or injury to sun-exposed areas of the body. This can include wearing protective clothing, such as hats and sunglasses, using sunscreen with a high sun protection factor (SPF), and seeking shade during peak sun hours.
Avoiding Trauma and Injury
Additionally, avoiding behaviors that may lead to trauma or injury to the lips or ears can help reduce the risk of developing venous lake. This can include being mindful of biting or injuring these areas and seeking prompt medical attention if any trauma occurs.
Special Considerations for High-Risk Individuals
It is also important for individuals with a family history of venous lake to be aware of their increased risk and take proactive steps to protect their skin from sun exposure and minimize potential injury.
When to Seek Medical Help for Venous Lake
While venous lake is generally harmless and does not require medical intervention, it is important to seek medical attention if there are any concerns about changes in the appearance or behavior of the lesion. This can include sudden bleeding, ulceration, rapid growth, or any other unusual symptoms associated with the venous lake. Additionally, individuals who are considering treatment options for cosmetic reasons should consult with a healthcare professional to discuss their options and ensure they receive appropriate care based on their individual needs.
Overall, while venous lake is generally benign and does not pose any serious health risks, it is important to stay vigilant about any changes in its appearance and seek medical attention if there are any concerns.

FAQs
What is a venous lake?
A venous lake is a small, dark blue to purple, benign vascular lesion that typically appears on sun-exposed areas of the skin, such as the lips or ears. It is caused by the dilation of small blood vessels, known as venules, near the skin’s surface.
What are the symptoms of a venous lake?
Venous lakes are typically asymptomatic, meaning they do not cause any pain or discomfort. They are usually noticed due to their characteristic appearance as small, raised, blue to purple lesions on the skin.
What causes a venous lake?
The exact cause of venous lakes is not fully understood, but they are believed to be related to sun exposure and the aging process. They are more commonly seen in older individuals and are often found on areas of the skin that have been exposed to the sun for long periods of time.
How are venous lakes diagnosed?
Venous lakes are typically diagnosed based on their characteristic appearance. In some cases, a dermatologist may perform a biopsy to confirm the diagnosis and rule out other potential skin conditions.
Can venous lakes be treated?
Yes, venous lakes can be treated. Common treatment options include laser therapy, cryotherapy (freezing the lesion with liquid nitrogen), or surgical excision. It is important to consult a dermatologist to determine the most appropriate treatment for each individual case.
Are venous lakes cancerous?
No, venous lakes are benign and non-cancerous. They do not pose a risk of developing into skin cancer. However, it is important to have any new or changing skin lesions evaluated by a dermatologist to rule out more serious conditions.
