The hemangioendothelium is a vascular tumor rarely seen in the pediatric practice. This case underlines the difficulty that lies in establishing a differential diagnosis with a localized adenopathy when this vascular tumor is developing inside a ganglionic region. The surgical treatment followed by interferon therapy determined a favorable evolution in this case because the hemangioendothelium is a vascular borderline tumor. Still, there are cases that recur, metastasize and have an evolution towards death.
