Symmetrical peripheral gangrene: a rare complication of dengue fever

Symmetric peripheral gangrene is associated with a variety of infective and non-infective etiologies. SPG is always presented with disseminated intravascular coagulation (DIC) and carries a higher mortality. Herein, we describe a 42-year-old female with dengue fever and rash developed bilateral symmetric dry gangrene of 2 nd and 3 rd toes. There was no history of taking B-blockers, ergot etc. All the peripheral pulses of the affected limbs were palpable. Color Doppler of lower limb vessels was done, which indicated normal flow. Blood was positive for Fibrin degradation products and D dimers. Patient was managed with IV fluids, LMWH, FFP etc. Her general condition improved within 72 hours with no further progression of gangrene.
