Retiform Hemangioendothelioma

Retiform hemangioendothelioma is a rare vascular tumor that affects the blood vessels, particularly those in the skin. It is important to shed light on this condition to increase awareness and understanding, as well as to provide clear and concise information for individuals searching for related terms. Retiform hemangioendothelioma is a vascular tumor that primarily affects the skin’s blood vessels. It is considered a low-grade malignancy and falls under the category of intermediate vascular tumors. It is characterized by distinct microscopic patterns resembling a fishnet or net-like structure, which is where its name “retiform” is derived. Hemangioendothelioma refers to a tumor originating from the endothelial cells lining the blood vessels.

The symptoms of retiform hemangioendothelioma can vary from person to person. The most common symptom is the appearance of red or purplish nodules or papules on the skin, especially in the extremities. These growths may be accompanied by itching, pain, or tenderness. In some cases, the tumor may bleed or ulcerate, leading to potential infection. It is important to note that symptoms can be nonspecific and may resemble other skin conditions, making an accurate diagnosis crucial.

Types

Types of Retiform Hemangioendothelioma:

  1. Classic Retiform Hemangioendothelioma:
    • This type of retiform hemangioendothelioma presents as a slow-growing tumor that predominantly occurs on the extremities or trunk.
    • Symptoms may include the development of reddish-brown nodules, pain, swelling, or ulceration.
    • Treatment options include surgical excision, radiation therapy, or observation, depending on the size and location of the tumor.
  2. Cutaneous Retiform Hemangioendothelioma:
    • Cutaneous retiform hemangioendothelioma manifests as a skin lesion and is commonly found on the lower extremities or trunk.
    • It often presents as a solitary, reddish-blue or violaceous nodule that may grow over time.
    • Treatment usually involves surgical removal of the lesion, and recurrence rates are generally low.
  3. Retiform Hemangioendothelioma with Kasabach-Merritt Phenomenon:
    • In this type, retiform hemangioendothelioma is associated with the Kasabach-Merritt phenomenon, a condition characterized by severe thrombocytopenia (low platelet count) and coagulopathy (impaired blood clotting).
    • Symptoms include rapid enlargement of the tumor, spontaneous bleeding, and bruising.
    • Treatment typically involves a multidisciplinary approach, including medical management to control bleeding, surgical intervention, embolization, or chemotherapy.
  4. Extra-cutaneous Retiform Hemangioendothelioma:
    • Extra-cutaneous retiform hemangioendothelioma primarily affects organs other than the skin, such as the liver, bone, or soft tissue.
    • Symptoms depend on the specific organ involved and may include pain, swelling, or functional impairment.
    • Treatment options vary based on the location and extent of the tumor and may include surgical resection, radiation therapy, or systemic therapy.
