Blood blisters, also known as hemorrhagic blisters, are a type of skin lesion that occurs when blood vessels in the skin are damaged, leading to the accumulation of blood under the skin's surface. They can appear as small, raised, red or purple bumps on the skin, and are often painful to the touch. Blood blisters can be caused by a variety of factors, including injury, friction, or certain medical conditions.
Characteristics and Causes of Blood Blisters
Blood blisters are typically characterized by their distinctive appearance, which can vary in size, shape, and color. They often have a rounded or oval shape and can range in size from a few millimeters to several centimeters in diameter. The color of a blood blister can also vary, but it is often red, purple, or blue due to the presence of blood under the skin. Blood blisters can be caused by a variety of factors, including trauma or injury, friction or pressure, and certain medical conditions such as diabetes or poor circulation.
Types of Blood Blisters
There are several types of blood blisters, including subungual hematomas, which occur under the fingernails or toenails, and intradermal hematomas, which occur within the layers of the skin. Blood blisters can also be classified based on their location, with palmar or plantar hematomas occurring on the palms of the hands or soles of the feet, and digital hematomas occurring on the fingers or toes.
| Type of Blood Blister | Characteristics |
|---|---|
| Subungual Hematoma | Occurs under the fingernails or toenails, often caused by trauma or injury |
| Intradermal Hematoma | Occurs within the layers of the skin, often caused by friction or pressure |
| Palmar or Plantar Hematoma | Occurs on the palms of the hands or soles of the feet, often caused by trauma or injury |
| Digital Hematoma | Occurs on the fingers or toes, often caused by trauma or injury |
In terms of images, blood blisters can appear in various forms, including:
- Small, rounded bumps on the skin, often with a red or purple color
- Larger, more irregularly-shaped lesions, which can be painful to the touch
- Blister-like formations under the skin, which can be filled with blood or fluid

Treatment for blood blisters typically involves protecting the affected area from further injury or friction, and applying topical creams or ointments to promote healing and reduce pain. In some cases, medical attention may be necessary to drain the blood blister or treat any underlying conditions. Prevention of blood blisters can be achieved by wearing protective clothing or gear, such as gloves or shoes, and avoiding activities that cause friction or trauma to the skin.
