Childhood Vascular Tumors

Definition

Childhood vascular tumors are rare cancers that form in the blood vessels. They include several types, such as infantile hemangioma, kaposiform hemangioendothelioma, and angiosarcoma.

Characteristics

Most vascular tumors are benign, but some can be aggressive or life-threatening. Symptoms depend on the tumor type and location, and may include a visible mass, swelling, pain, or skin discoloration. In severe cases, they can cause bleeding or interfere with organ function.

Diagnosis and Prognosis

Diagnosis involves physical examination, imaging tests like ultrasound, MRI, or CT scans, and biopsy when necessary. Prognosis depends on the tumor type and whether it is benign or malignant. Many vascular tumors, especially hemangiomas, have a good outcome.

Treatment

Treatment varies widely and may include observation for benign tumors, medication (such as beta-blockers for hemangiomas), surgery, chemotherapy, or radiation therapy for malignant or complicated cases.
