Another condition that is included in the differential diagnosis is pseudomyogenic hemangioendothelioma; this type is composed of tumor cells with spindle cell morphology (in contrast to the epithelioid morphology), lacks intracytoplasmic vacuoles, and lacks diffused expressions of CAMTA1 and TFE3 even with the expressions of the vascular markers (Jason and Hornick, 2011). The gene discussed is TFE3; the disease is hemangioendothelioma.
