Epidemiology
A benign tumor of fat with blood vessels, typical of young adults and sometimes multiple. It can be more painful than a common lipoma because of its vascular component, especially when it is subcutaneous and multiple.
Basic features
It is usually superficial, small, and tender to the touch, unlike many common lipomas.
Usual treatment
Simple removal is considered if it causes pain, grows, or is bothersome because of its location.
Outcomes and prognosis
The prognosis is excellent. Because they are often multiple, new nodules may appear elsewhere over time: that is not a recurrence of the one already removed, and only those that cause trouble are operated on.
