Pediatric facial kaposiform hemangioendothelioma: a case report and review of the literature

Cutaneous kaposiform hemangioendothelioma (KHE) and tufted angioma (TA) are vascular tumors that are often misdiagnosed. Treatment urgency and type varies depending on which tumor-type is diagnosed, because of the differing rates of progression to Kasabach–Merritt phenomenon. An 11-month-old male presented with a facial mass and biopsy results favoring a diagnosis of TA. The diagnosis of KHE, was later favored over TA given the overall clinical picture of initial rapid growth. However, serial imaging showed no subsequent growth, suggesting that clinically diagnosed KHE, may follow a benign clinical course when biopsy results suggest a diagnosis of TA.
