Hot lesions: what are they?

Heat injuries cause redness, inflammation, and infection of the skin or organs. They can be caused by scratches or rubbing, and may have a clear or discolored discharge. AIDS skin lesions are prone to infection and take longer to heal. Small skin lesions can be removed in a doctor’s office, while liver lesions require laparoscopic surgery. Brain lesions in MS patients can become heat lesions but are usually not removed due to the risks of brain surgery.

Heat injuries are open injuries to the skin or another organ that cause redness, inflammation, or infection of the area. The inflammation causes the affected tissue to become warm when palpable. These lesions are usually cutaneous, meaning they are on the skin and have usually been scratched or rubbed, causing more inflammation and pain. Many warm wounds will have a thin, clear fluid discharge due to the inflammatory response of the immune system, or the wound may develop a thick, discolored discharge from bacteria growing in the wound. Some types of lesions develop from cutaneous acquired immunodeficiency syndrome (AIDS) lesions, liver lesions, and hyperintense brain lesions that develop from multiple sclerosis (MS).

AIDS skin lesions are typically prone to infection due to reduced function of the person’s immune system. The infection can cause the area to become inflamed, causing the surface of the wound to crack. Generally, lesions found on the skin of AIDS patients will take longer to heal, giving the lesion more time to develop a life-threatening infection. The doctor involved will need to factor in a longer recovery period before determining which removal procedure to use.

A small warm skin lesion may be removed in the doctor’s office. Smaller wounds may not require stitches or sutures to close the wound after removal. Large lesions or lesions involving many blood vessels may need to be removed by a surgeon. Recovery time is usually minimal, with the patient able to resume their normal activities within two days.

Liver injuries that may become hot are usually more serious in nature. This type of lesion is called an adenoma and is one of the largest lesions found on the liver. As the lesion increases in size, the surface can break down and cause bleeding and internalized pain. The lesion will need to be removed by laparoscopic surgery. This type of surgery is done by making two to three small incisions and inserting a surgical tool with tiny forceps on the end that allows the surgeon to remove the hot lesion without creating a large abdominal wound.

The hyperintense brain lesions found in MS patients could become heat lesions. The number of lesions found on the brain can indicate the level of disability and pain the patient will experience. As hyperintense lesions become inflamed and open, the lesion becomes a warm lesion. Lesions located on the brain are usually not removed, due to the risks associated with brain surgery.
