What causes black spots on scrotum?
Angiokeratomas are benign tumors that form within the blood vessels of the skin. They cause no symptoms except for occasional pain when passing urine or stool. Angiokeratomas do not usually spread beyond their original location and there is little risk of them spreading outside the body.
The most common type of angiokeratoma is called a “trench” angiokeratoma. Trenches are formed from the blood vessel walls around the veins which carry blood away from the heart. The vein itself may be small, but it carries enough pressure to cause a hole in the wall of the vein. When this happens, a pocket forms where there was once a normal vein. If left untreated, these pockets will grow into large masses that can block up major arteries leading to vital organs such as your brain or lungs if they become blocked completely.
Treatment of Angiokeratomas
There are several treatments available for angiokeratoma. These include surgery to remove the mass, medications to reduce its size, and other procedures that try to keep it from growing back. Surgery is generally reserved for larger masses that could potentially block up major arteries leading to vital organs like your brain or lungs if they become blocked completely.
Surgery for angiokeratomas can be rather complex. The surgeon must be very careful not to cut into a major blood vessel or otherwise damage any tissue because of the mass’s proximity to such things. If not, the patient could bleed to death. Using a laser to cauterize the blood vessels is much safer, but it is only an option for smaller masses.
Other types of treatment involve using a low dose radiation to prevent it from growing back after surgery. If this is not effective, the only other option is to perform a second surgery to remove what remains.
Surgery or aggressive medication use should be a last resort because angiokeratomas are benign tumors and are not known to spread (metastasize) outside the skin. Most of the time, they do not grow back at all once removed and the risk of serious complications is very low.
What are angiokeratomas?
Angiokeratomas are benign (not Cancer) growths on the skin that form from blood vessels. These growths can appear anywhere on the skin but are most common on the legs. They often appear as small red areas that feel raised relative to the rest of the skin. They may also appear as small bumps that are red at the core and have clear edges. These growths are often itchy or painful if they occur in areas that are prone to rubbing, such as the knees or elbows.
While angiokeratomas are not life-threatening, they can be disfiguring if they appear on visible areas of the body. They are also prone to bleeding if they become irritated or bumped. If you have a growth on your skin that matches this description, please see a dermatologist to determine the best treatment option for you.
