Case 34
A 24-year-old lady requests removal of the dark supraclavicular lesion.
History
How long have you had this lesion?
Since I was born.
Such lesions usually are present at birth or appear soon thereafter.
Has it grown recently?
No.
These lesions may grow in infancy, but then many regress. Some remain stable, but none grow in adulthood.
Does it itch?
No.
Most vascular lesions do not itch.
Does it get pale when you press on it?
Yes.
When a lesion is vascular, it will blanch or disappear with pressure. A physician uses a glass slide or spatula to test this, the procedure is known as diascopy.
Do you have any other similar lesions?
Yes, I have three on my back.
The most common sites are the face, neck and trunk.
Did it ever bleed?
No.
If such a lesion is injured, bleeding is likely, but easily stopped with pressure.
