Abstract:

A 32-year-old right-handed male presented with a lump on the right middle arm that had been present for 3 to 4 months. The MRI reports an 8 mm nodular formation in contact with the humeral artery and vein between the middle and distal third of the right arm that undergoes enhancement after administration of venous contrast in close contact with branching of the radial artery. In surgery it was observed a pedunculated lesion from the humeral artery, in principle compatible with a pseudoaneurysm which compromised the integrity of the vascular lumen, so a bypass was performed with a basilic branch graft. The anatomopathological result showed a highly vascularized tumor proliferation and hemorrhagic suffusions made up of epithelioid cells that suggest the differential diagnosis between epithelioid hemangioendothelioma, pseudomyogenic hemangioendothelioma or epithelioid angiosarcoma among other vascular tumors. Finally, a second surgery was performed because there were doubts about having free margins with a new bypass with the ipsilateral saphenous vein. In molecular studies CD34, CK, ERG and FOSB were +++ so an epithelioid hemangioma was the definitive diagnosis. Although rare, vascular tumors should be considered in the differential diagnosis when a mass is associated with an artery. Pathological diagnosis and obtaining free margins given the possibility of malignant recurrence of this tumor are essential.
