Blue Blister on Forearm
A 55-year-old male mechanic presented with an unclear painful swelling (4 × 6 cm) on his right forearm. He reported having had a “blue blister.” The lesion had appeared suddenly a few weeks earlier, with no relevant injury or manipulation. The rest of the venous vascular system showed no abnormalities. Duplex sonography revealed a varicose venous aneurysm. The vascular swelling disappeared when the patient kept his arm raised for some time. Surgical treatment was indicated because of the high risk of injury to this right-handed man in the workplace. After elimination of the aneurysm of the superficial antebrachial segment of the cephalic vein, histological examination of the excised tissue showed venous ectasia and phlebosclerosis with no sign of malignancy. The patient was discharged free of symptoms the day after surgery.
