Childhood Angiosarcoma: A Rare and Aggressive Cancer

Childhood angiosarcoma is a rare and aggressive type of cancer that affects the blood vessels or lymph vessels in children. It is a type of soft-tissue sarcoma, which are solid tumors that begin in tissues that connect, support, or surround organs and other body tissue.

Incidence and Prevalence

Angiosarcoma is an extremely rare cancer in children, occurring in only about two people per million [2]. The exact incidence and prevalence of childhood angiosarcoma are not well-documented due to its rarity.

Symptoms and Diagnosis

The symptoms of childhood angiosarcoma vary depending on the location and size of the tumor. Common symptoms include:

• A raised area of skin that looks like a bruise
• A bruise-like lesion that grows larger over time
• A lesion that may bleed when scratched or bumped [10]
• Reddish or blue small lumps that eventually spread, grow bigger, and bleed easily [11]

Diagnosis is typically made through a combination of physical examination, imaging tests (such as CT or MRI scans), and biopsy.

Treatment Options

Treatment for childhood angiosarcoma depends on the location, size, and stage of the tumor. Treatment options may include:

• Surgery to remove the tumor
• Targeted drugs if the cancer is advanced [13]
• Immunotherapy to help the immune system fight the cancer

It's essential to note that treatment plans are individualized and determined by a child's medical team based on their health and the specific characteristics of the tumor.

Prognosis

The prognosis for childhood angiosarcoma varies depending on the stage and location of the tumor. Unfortunately, this type of cancer is often diagnosed at an advanced stage, which can affect treatment outcomes.

Childhood angiosarcoma can manifest in various ways, depending on its location in the body. Here are some possible signs and symptoms:

• Bruised area that may bleed easily: If the cancer is near the surface of the skin, a bruised area may appear, which can be painful and bleed easily when scratched or bumped.
• Swelling: The affected area may become swollen, indicating inflammation and potential tumor growth.
• Pain in the affected area: Children with angiosarcoma growing in an organ deeper in the body may experience pain in the area where the cancer is located.
• Shortness of breath (dyspnea): If the cancer affects the heart or lungs, symptoms like shortness of breath may occur.
• Chest pain: Cardiac angiosarcoma can cause chest pain due to tumor growth and pressure on surrounding tissues.

It's essential to note that these symptoms can vary depending on the location and severity of the cancer. A correct diagnosis by a medical professional is crucial for proper treatment and management.

Childhood angiosarcoma, a rare type of cancer, requires accurate and timely diagnosis to ensure effective treatment. Diagnostic tests play a crucial role in identifying this condition.

Common diagnostic tests for childhood angiosarcoma:

• Blood and urine tests [1]
• Ultrasound [1]
• Advanced imaging studies such as MRI, CT, or PET scan to determine the tumor's size and location [2], [6]
• Biopsy, which involves taking a sample of the tumor tissue for microscopic examination by a pathologist [3], [7]

Additional diagnostic tests:

• Bone scans may be ordered to check for any spread of the cancer [2]
• CD34 immunohistochemistry can aid in the diagnosis by highlighting the vascular nature of angiosarcomas [9]

Importance of accurate diagnosis: A definitive diagnosis of childhood angiosarcoma is essential for developing an effective treatment plan. The diagnostic tests mentioned above help identify the tumor's characteristics, which inform the treatment approach.

Differential Diagnoses for Childhood Angiosarcoma

Childhood angiosarcoma, a rare and aggressive tumor, requires careful consideration of its differential diagnoses to ensure accurate diagnosis and treatment. The following conditions are often considered in the differential diagnosis of childhood angiosarcoma:

• Kaposi sarcoma: A type of cancer that affects the skin and mucous membranes, particularly in children with weakened immune systems [1].
• Epithelioid hemangioendothelioma: A rare tumor that arises from blood vessels, which can be difficult to distinguish from angiosarcoma based on histological features alone [2].
• Hemangiopericytoma: A type of vascular tumor that can mimic the appearance of angiosarcoma under microscopic examination [3].
• Spindle cell hemangioendothelioma: A rare tumor that shares some similarities with angiosarcoma, but typically has a more benign clinical course [4].

Imaging and Histological Considerations

In addition to these differential diagnoses, imaging studies such as MRI or CT scans may not provide specific findings for childhood angiosarcoma, making it difficult to distinguish from other brain tumors like gliomas or cavernomas [5]. Biopsy is often necessary to confirm the diagnosis of angiosarcoma.

Rare and Aggressive Nature

It's worth noting that hepatic angiosarcoma, a rare form of angiosarcoma affecting the liver, has a poor prognosis in children, with fewer than 50 cases reported in the literature [6].
