Haemangiomas are benign tumors formed by the dilation of blood vessels or the formation of new ones by the proliferation of endothelial cells. Their etiology remains unknown, but in many cases they are related to hereditary factors.

The most common types are:

  • Infantile proliferative haemangioma: It appears as a soft little red nodule that develops from birth and usually disappears by itself by the age of five.
  • Angiokeratoma: acquired scaly angiomas, usually on vulva or scrotum.
  • Asteroid hemangioma: they are mainly found on the face, chest and upper limbs and are most commonly seen in women. They do not cause pain and are not dangerous.
  • Cherry angioma or Campbell de Morgan spots: they usually appear after the age of 30. They are so common that after the age of 75 they affect almost 80% of the population. They present as firm red, blue or purple papule, 0.1–1 cm in diameter. When thrombosed, they can appear black in color. They are treated with therapeutic techniques such as electrosurgery, cryotherapy and laser.
