Cerebellar hemangioendothelioma.
We report a 26-year-old woman with cellular hemangioendothelioma that may be the third case diagnosed as cerebellar hemangioendothelioma. The tumor was composed of numerous vascular channels lined by endothelial cells and aggregates of large round endothelial cells. Transitional cells were also present. The large round cells were positive for CD34 and vimentin in their abundant cytoplasm that contained 1 or some red blood cells, revealing intracytoplasmic lumina. The patient remains free of disease over 5 years after tumor resection.
