Blue rubber blister nevus syndrome: this syndrome is rare. It is characterized by cavernous or capillary hemangioma of the skin and digestive tract at the same time. The tumor presents as blue nevus. If rupture occurs, it can lead to bleeding. Let's share my experience with you.

How does blue rubber bullous mole cause?

It is an autosomal dominant hereditary disease caused by the disorder of embryonic differentiation and development. There are three kinds of pathological changes in the skin or digestive tract: 1. Large cavernous hemangiomas replace normal tissues, affect vital organs and block tubular structures such as the intestine and trachea.

2. The blood sac is a blue rubber nipple covered with thin skin.

3. Irregular blue spots, sometimes punctate, invade the surrounding normal skin, thus changing from blue black, blue, light blue to normal skin color. Histological examination showed capillary or cavernous hemangioma with smooth muscle fibers between the walls and sweat glands near the blood vessels.

Pustule: pustule is a localized epidermal cavity bulge, containing turbid pus. It originated from the skin and evolved from papules and blisters. Pustules vary in size and depth. There may be inflammatory red halo around them. Shallow pustules dry up and become purulent scabs, leaving no scars after healing. Deep pustules can form ulcers, leaving scars after healing.
