It has been shown recently that Kasabach-Merritt phenomenon, the association of a vascular tumour and consumption coagulopathy, does not--as previously thought--complicate "classical" infantile hemangiomas but distinctive entities called kaposiform hemangioendothelioma (KHE) and tufted angioma (TA), both tumours on the same neoplastic spectrum. These tumours have been found in the neck, face, thorax, abdomen, retroperitoneum and limbs and are associated with a mortality rate of as high as 30 %. Several therapeutic modalities, including alpha-interferon, vincristine, radiotherapy and surgery have been reported in the literature. We report a case of retroperitoneal kaposiform hemangioendothelioma regression using alpha-interferon and discuss the current knowledge of this entity and its treatment.

Kaposiform hemangioendothelioma (KHE) is a rare vascular tumor that typically presents in infancy or early childhood. As awareness of KHE increases, it is imperative that the management of KHE be updated to reflect the latest evidence-based guidelines. The aim of this study was to integrate the literature and Chinese expert opinions to provide updated recommendations that will guide the diagnosis, treatment, and prognosis of patients with KHE.

Vascular anomalies are broadly classified into 2 categories: vascular tumors and vascular malformations. Vascular anomalies frequently present as cutaneous lesions in infants. This review summarizes vascular anomalies that most commonly present as dermatologic lesions in the neonatal period, with a focus on the clinical findings, pathophysiology and histology, relevant radiographic findings, and management of common vascular anomalies such as infantile hemangiomas, congenital hemangiomas, and Kaposiform hemangioendothelioma, along with vascular malformations, including capillary, lymphatic, venous, and arteriovenous malformations.

Background: Kaposiform hemangioendothelioma is a rare vascular tumor primarily occurring in infants and children. The most common sites for kaposiform hemangioendothelioma are extremities, with very few cases of abdominal kaposiform hemangioendothelioma reported in neonates. Making a diagnosis of Kaposiform hemangioendothelioma can be challenging when the patient presents with generalized symptoms such as bilious vomiting and constipation that can be attributed to other more common causes of intestinal obstruction.

The role of the hematologist in the management of vascular anomalies is evolving. Several vascular tumors and malformations are associated with complex coagulation derangements. Kaposiform hemangioendothelioma or tufted angiomas may present with a consumptive coagulopathy known as the Kasabach-Merritt phenomenon (KMP).
