Hemangioendothelioma is used to describe a group of vascular neoplasms that may be considered benign as well as malignant, depending on the specific group member's activity.

Classification

Hemangioendotheliomas may be classified as:

• Epithelioid sarcoma-like hemangioendothelioma is an exceedingly rare vascular tumor of intermediate grade that was first described by Steven Billings, Andrew Folpe, and Sharon Weiss in 2003. These tumors are so named because their histologic appearance is very similar to that of epithelioid sarcoma, a more malignant tumor with which they are commonly mistaken.
• Composite hemangioendothelioma is a low-grade angiosarcoma typically occurring in adults, although it has been described in infancy.
• Spindle-cell hemangioendothelioma) is a vascular tumor that was first described in 1986 by Sharon Weiss, M.D., and commonly presents in a child or young adult who develops blue nodules of firm consistency on a distal extremity. These tumors were reclassified by Dr. Weiss in 1996 as "spindle cell hemangioma", rather than hemangioendothelioma, due to the excellent prognosis observed in a group of 78 patients.

• Retiform hemangioendothelioma (also known as a "Hobnail hemangioendothelioma") is a low-grade angiosarcoma, first described in 1994, presenting as a slow-growing exophytic mass, dermal plaque, or subcutaneous nodule.

• Kaposiform hemangioendothelioma (also known as "Infantile kaposiform hemangioendothelioma") is an uncommon vascular tumor, first described by Niedt, Greco, et al (Hemangioma with Kaposi's sarcoma-like features: report of two cases.(Niedt GW, Greco MA, Wieczorek R, Blanc WA, Knowles DM 2nd. that affects infants and young children, with rare cases having also been reported in adults.Pediatr Pathol. 1989;9(5):567-75.)

• Endovascular papillary angioendothelioma, also known as "Dabska tumor", "papillary intralymphatic angioendothelioma" (PILA), "Dabska-type hemangioendothelioma", "hobnail hemangioendothelioma", and "malignant endovascular papillary angioendothelioma", is a rare low-grade angiosarcoma of lymphatic channels. Approximately 30 such tumors have been described in the medical literature. Although included in the World Health Organization tumor classification, there is uncertainty as to whether EPA is a distinct entity or a heterogenous group of tumours. The lesion usually presents as a slow-growing tumor of the skin and subcutaneous tissues of the head, neck, or extremity, of infants or young children. However, EPA has involved the testicle, deep muscle tissue as a neoplastic transformation of a larger existing benign cavernous hemangioma, bone and spleen, and has been found in adults. Some reports indicate a good prognosis but metastasis is occasionally seen.

• Infantile hemangioendothelioma is a rare benign vascular tumour arising from mesenchymal tissue and is usually located in the liver. It often presents in infancy with cardiac failure because of extensive arteriovenous shunting within the lesion. It is the third most common liver tumor in children, the most common benign vascular tumor of the liver in infancy, and the most common symptomatic liver tumor during the first 6 months of life. These hemangioendotheliomas have 2 growth phases: an initial rapid growth phase, which is followed by a period of spontaneous involution (usually within the first 12 to 18 months of life). Detection of the hemangioendothelioma within the first 6 months of life is attributed to the initial rapid growth during this time; however, the tumor has been detected with fetal ultrasonography. Histopathologically, there are 2 types of hepatic hemangioendotheliomas:
  • Type I: Hemagioendotheliomas of this type have multiple vascular channels that are formed by an immature endothelial lining with stromal separation from bile ductules.
  • Type II: These hemangioendotheliomas have an appearance that is more disorganized and hypercellular, and there are no bile ductules.

In children, distinguishing between a primary malignant liver tumor (hepatoblastoma) and a benign primary hepatic lesion (hemangioendothelioma) is crucial. The absence of urinary catecholamines supports the diagnosis of hemangioendothelioma. In patients with hemangioendotheliomas, elevations in α₁-fetoprotein levels are milder than those found in patients with hepatoblastomas. Infantile hepatic hemangioendothelioma is strongly suggested by the presence of a vascular lesion on imaging studies. A complex, heterogeneous mass is often seen on ultrasonograms; a complex tumor that lacks central enhancement can be see on CT scans; and the vascular nature of the lesion along with dilation of the aorta proximal to the origin of the celiac artery and a decrease in the diameter distally, indicating significant shunting, is seen on angiograms. Because most hemangioendotheliomas in infants sponanteously involute and regress within the first 12 to 18 months of life, asymptomatic lesions are generally managed conservatively. Infants who have severe anemia and/or thrombocytopenia can be given blood products; for those who have cardiac failure, diuretics and digoxin are often given. To stop further growth and to speed regression of lesions in infants with more significant clinical sequelae, treatment with corticosteroids or interferon-α-2a is administered. To slow the growth of tumors that are rapidly enlarging, chemotherapy and radiation therapy have been used. Surgical resection, partial hepatectomy, and embolization of afferent vessels should be considered for severe cases.

Signs and symptoms

They have been described as masses that fall between a hemangioma and angiosarcoma. They are vascular tumors that commonly present with an enlarging mass and most commonly involve the lungs, liver, and musculoskeletal system, although many other body sites have been reported, including the head and neck, intestines, lymph nodes, pleura, retroperitoneum, stomach.

Treatment

Treatment is varied and depends on the site and extent of tumor involvement, site(s) of metastasis, and specific individual factors. Surgical resection, radiotherapy, and chemotherapy have all been used to treat these masses, although studies on survival have yet to be conducted to delineate various treatment regimens.

• Li B, Li Y, Tian XY, Li Z.AbstractPapillary intralymphatic angioendothelioma (PILA) or Dabska tumor is extremely rare, and often affects the skin and subcutaneous tissues of children. Since its first description by Dabska, only a few intraosseous cases have been described in the literature and none of them presents with multifocal osteolytic lesion of bones. We present a case of unusual multifocal intraosseous PILA in facial bones occurring in a 1 year 3 month old male child. Computed tomography (CT) scan revealed multifocal osteolytic lesions were located at the left zygoma, left orbital bone and right maxillary. Histologically, the lesions were ill-defined and composed of multiple delicate interconnecting vascular channels with papillae formation which projected into the lumen lined by atypical plumped endothelial cells. The vascular channels were also lined by plump cuboidal endothelial cells with focal hobnailed or "match-head" appearance. In some areas, endothelial cells formed solid-appearing aggregates with vessel lumens. By immunohistochemistry, the tumor cells were positive for CD31, CD34 and D2-40 at varying intensity. A final diagnosis of intraosseous PILA was made. To the best of our knowledge, this case is the first case of primary multifocal osseous PILA.Virtual slidesThe virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/1919488629100787.
