A 58-year-old man presented with an acutely painful swollen left leg w
hich was cyanotic and crowded with cutaneous bullae. After confirmatio
n with color duplex ultrasound, intravenous streptokinase therapy was
commenced with a bolus of 250,000 IU followed by maintenance infusion
of 100,000 IU hourly for 72 hours. Treatment was changed to heparin fo
r 14 days and then oral warfarin for another 6 months. Effacement of b
ullae accompanied subsidence of swelling of the leg. This case highlig
hts the potential contribution of fluid retention in acute deep venous
thrombosis to extensive bullae formation. This has not been previousl
y reported in the literature.
