Hemangioendothelioma arising from the spleen: A case report and literature review

Abstract

Primary hemangioendotheliomas (HEs) of the spleen are rare, low-grade borderline-malignant vascular tumors. To date, only a few splenic HE cases have been reported in adults. In infants, one 9-year-old male patient has previously been reported, and the patient succumbed to the disease shortly following surgery. Currently, the clinical treatment and prognosis of the disease remains challenging to define, due to the extremely low number of cases reported. The current report presents the case of a 9-year-old pediatric patient with splenic HE, who survived with no recurrence or complications following a partial splenectomy. Additionally, a literature review was conducted to analyze the treatment and prognosis of the disease.
