label_lc: epithelioid hemangioendothelioma with yap1-tfe3 gene fusion
description: "Epithelioid hemangioendothelioma characterized by a YAP1-TFE3 gene fusion. This gene fusion occurs in a subset of epithelioid hemangioendotheliomas characterized by the presence of well-formed vessels lined by epithelioid endothelial cells with abundant eosinophilic cytoplasm. Patients with YAP1-TFE3 gene fusion tumors tend to be younger than those with a WWTR1-CAMTA1 gene fusion."
