However, the GLUT-1 transporter is still of debate: while frequently being regarded to be specific for infantile hemangioma, it is expressed similarly by other tumors [17]; recent publications have demonstrated positive GLUT-1 staining also in epitheloid hemangioendotheliomas, angiosarcomas, and angiokeratomas, whereas it was confirmed to be negative in most vascular malformations [18]. Here, SLC2A1 is linked to capillary hemangioma.
