Abstract
Tufted hemangiomas are relatively rare benign vascular proliferations that are congenital or appear during the first years of life. Herein we present an additional case of tufted hemangioma that appeared one year after birth and discuss its histopathological criteria and differential diagnosis with malignant vascular proliferations including sarcoma Kaposi, angiosarcoma and kaposiform hemangioendothelioma.

The vascular proliferation was positive for CD31, CD34, D2-40 and negative for HHV8
Summary
Tufted hemangiomas are relatively rare benign vascular proliferations that are congenital or appear during the first years of life. We present an additional case of tufted hemangioma that appeared one year after birth and discuss its histopathological criteria and differential diagnosis with malignant vascular proliferations including sarcoma Kaposi, angiosarcoma and kaposiform hemangioendothelioma. Dilated slit-like vascular spaces, resembling those of lymphatic vessels, were seen in the sclerotic stroma (Figures 2-4). Cracked irregular spaces were seen between the cells in the proliferation (Figure 5).
