We present a case of Plasmodium vivax malaria who presented with distal lower limb gangrene. Large vessels of the lower limb were normal. After ruling out other causes, a diagnosis of symmetrical peripheral gangrene was made. The dry gangrene was treated conservatively, and amputation planned after the line of demarcation was seen.

A 20-year-old man presented with 10 days history of high-grade intermittent fever with chills and rigors followed. The patient had noticed blackish discoloration of the toes 1 week after the onset of fever. There was no history of headache or seizures. There was no history of jaundice, bleeding manifestations, or decreased urine output. There was no history of similar history in past. He had no history of transfusions. On examination, he was febrile; there was no pallor, jaundice, or purpure. Mild dehydration was present. He had hepatosplenomegaly. There was bilateral dry gangrene involving the distal feet and toes with clear line of demarcation. All lower limb peripheral pulses were equal and symmetrical. Upper limbs examination was normal. Cardiovascular system examination revealed no abnormalities. There were no signs of meningeal irritation. Fundus was within normal limits. A peripheral smear showed ring forms of Plasmodium vivax and thrombocytopenia (platelet count 95,000/mL). Malarial antigen test was also positive. To evaluate for disseminated intravascular coagulation (DIC), prothrombin time, activated partial thromboplastin time, D-dimer, and fibrin degradation product were done which were all within normal limits. Antinuclear antibody was negative. Liver enzymes were raised (serum glutamic oxaloacetic transaminase - 256, serum glutamic pyruvic transaminase - 262). Renal functions were normal. Arterial Doppler of lower limbs was normal. With a provisional diagnosis of complicated vivax, malaria patient was treated with artemisinin-based combination therapy (artemether and lumefantrine) and other supportive measures. He became afebrile after 2 days. A peripheral angiogram showed normal large vessels of the lower limbs. Vascular surgery opinion was taken, and amputation was planned. Mummification of the feet and toes occurred after 2-3 weeks [Figure 1] and [Figure 2]. A diagnosis of symmetrical peripheral gangrene (SPG) complication P. vivax was made.
SPG was first described by Hutchison in 1891.  It is defined as distal symmetric ischemic damage in two or more areas without large vessel obstruction or vasculitis.  In spite of first being reported in the 19 th century, most documented cases in literature have been in the form of case reports. A few case series have been published in the last decade. ,, It has commonly been reported in association with DIC and septicemia. ,
Malaria-induced gangrene has been reported with falciparum, vivax, and mixed malaria in India. , Gangrene associated with severe malaria has also been reported from Thailand and African countries such as Zimbabwe and Kenya. ,, Some cases have also been reported in travelers returning from endemic countries.  Clemens et al. showed that severe malaria activates the intrinsic clotting pathway and complement system.  In their study, thrombin-AT III complexes were elevated, and protein C activity decreased in severe malaria. Malaria-induced gangrene commonly affects the distal limbs, ear and nose tip, and scalp. The management of malaria-induced gangrene remains in early identification of the identifying cause and its prompt treatment along with correction of DIC if present. The gangrenous extremity should be treated conservatively. The prognosis remains poor. Amputation has been reported in 8 out of 9 and 6 out of 9 survivors in different case series. , Mortality has been reported in 10-33% of patients. ,, Leukopenia has been associated with a worse outcome.
