Blood Lesions Under The Skin

Sudden unexplained bruising or blood spots under the skin or a sudden increase in the frequency of bruising may be caused by:

• A medicine, such as aspirin or blood thinners ( anticoagulants ).
• Infection that causes the buildup of toxin in the blood or tissues ( sepsis ).
• A bleeding or clotting disorder, such as hemophilia, von Willebrand’s disease, thrombocytopenia, or…

Common skin lesions Naevi. Naevi, the medical term for moles, are commonly raised or flat spots that occur on the skin genetically or as a… Acne. Acne is a widely common skin condition that ranges from mild to severe. The condition usually appears as skin… Hives. Hives are a rash of red bumps …

Acne, athlete’s foot (tinea pedis), warts, and scabies are examples of skin infections that cause lesions. Allergic reactions and sensitivity to outside environmental factors can also lead to the formation of skin lesions. Underlying conditions can also precipitate the appearance of skin lesions.

A lesion is any abnormal, or pathologically altered, tissue on or within an organism. Types of primary lesions include vesicles, pustules, wheals (welts) and tumors whilst secondary lesions include crusts, pigmentations, scales, scars and ulcers. They may be caused by any process that damages tissues from cancer to trauma and are classified by their location such as brain lesion or skin lesion.

Tiny blisters are often the result of pinched tissues in the underlying layer of skin, resulting in tiny red bumps appearing above the skin in the affected location. There are many other causes of tiny blisters, such as inflammation occurring within the body and an allergic response to certain medications, foods or substances in the environment.

Lesions are most often well circumscribed and round. The border of the lesion may be scaly or have small blisters. Lesions are often quite itchy. The diagnosis is easily confirmed by visualization of fungal elements in the skin scales after exposure to potassium hydroxide under the light microscope.

A skin lesion is an area of skin that is somehow different from the surrounding areas. Skin lesions can come in the form of a bump, a mole or a scar. They can be a sign of a simple allergy or a more serious skin condition. They can take the form of a spreading plaque or appear as a rounded welt.

A benign lesion is non-cancerous whereas a malignant lesion is cancerous. For example, a biopsy of a skin lesion may prove it to be benign or malignant, or evolving into a malignant lesion (called a premalignant lesion). Lesions can be defined according to the patterns they form.

A lesion is any damage or abnormal change in the tissue of an organism, usually caused by disease or trauma. Lesion is derived from the Latin laesio "injury". Lesions may occur in plants as well as animals.

Lesion Definition. Typically, a lesion involves an abnormal structural change to a tissue. So, it is often defined as a site of abnormal tissue change. These changes can take place in the form of wounds or bruising, but is also a term used by oncologists to describe wounds caused by malignant or benign (innocuous) cancers.

Bone lesions are a masses of tissue that can form in any part of the bone. Bone lesions can affect any part of the body and develop in any section of bone, from the surface to the bone marrow in the center. They are caused by cells in the bone that start to divide and multiply uncontrollably, leading to a lump or mass of abnormal tissue.

The key to understanding the question is the definition of a “lesion”. Various lesions may range from benign to serious. A lesion is a region in organ or tissue (in this case, the bladder) that is suffer damage through such mechanisms as follows:

Brain lesions are a type of damage to any part of brain. Lesions can be due to disease, trauma or a birth defect. Sometimes lesions appear in a specific area of the brain. At other times, the lesions are present in a large part of the brain tissue. At first, brain lesions may not produce any symptoms.

Blisters will usually heal on their own with the skin over the blister helping to keep out infection while new skin is formed underneath and the fluid is absorbed.

Several types of inflammatory conditions of the skin, allergic reactions, and sometimes bacterial, viral or fungal infections and insect bites can cause blisters on the skin.

Small blood blisters can be as a result of an injury to the blood vessels beneath the skin, often resulting in minor occurrence such as bruising. Bleeding into the skin can appear as small dots, called petechiae, or in larger, flat patches called purpura.

Some causes of a cluster of blisters are herpes, burns, and shingles. Cold sores and fever blisters are caused by an extremely common virus called herpes simplex. Severe burns can also cause a cluster of blisters and often require a health professional’s expertise. In addition, shingles is a virus much like chickenpox that is capable of producing blisters.
