Angiolipoma

Angiolipoma is a subcutaneous lipoma subtype, characterized by its vascular components. It is a benign tumor that primarily affects the subcutaneous layer of the skin. Angiolipomas are most commonly found in young adults and are often painful upon palpation.

Overview

Angiolipomas are composed of mature adipose tissue and blood vessels. They are typically small, ranging from 1 to 2 cm in diameter, and are often multiple. The most common locations for angiolipomas are the arms, chest, and back. However, they can occur anywhere in the body.

Symptoms

The primary symptom of an angiolipoma is a painful, tender mass beneath the skin. The pain is often described as a dull ache that worsens with pressure. Other symptoms may include redness and warmth over the area of the tumor.

Diagnosis

The diagnosis of angiolipoma is typically made through a combination of physical examination and imaging studies. Ultrasound and magnetic resonance imaging (MRI) can be used to visualize the tumor and its vascular components. A definitive diagnosis is made through a biopsy, where a small sample of the tumor is removed and examined under a microscope.

Treatment

The primary treatment for angiolipomas is surgical removal. This is typically done under local anesthesia and involves making a small incision over the tumor and removing it. In some cases, if the tumor is small and not causing symptoms, a watch-and-wait approach may be taken.

Prognosis

The prognosis for individuals with angiolipomas is generally excellent. These tumors are benign and do not spread to other parts of the body. However, they can cause discomfort and may recur after removal.
