Disseminated intravascular coagulation presenting as symmetrical peripheral gangrene: a case report

Plasmodium vivax was traditionally thought to be benign; however, nowadays it presents with a myriad of systemic complications like cerebral malaria, acute respiratory distress syndrome, acute kidney injury, acute pancreatitis, hepatic dysfunction, and disseminated intravascular coagulation, which were earlier attributed only to Plasmodium falciparum malaria. Here we report a case of a middle-aged man who presented with disseminated intravascular coagulation manifesting as symmetrical peripheral gangrene. What makes this case more interesting is that the malaria isolated was Plasmodium vivax instead of Plasmodium falciparum. Such findings were previously reported, but this is the first case where the patient was managed conservatively with antimalarial drugs without the need for amputation, which focuses on the very important role of early diagnosis and timely management.

A 44-year-old Indian man from north India presented with history of fever of 2 days' duration with severely painful cold extremities. No pulse could be recorded on examination. A diagnosis of symmetrical peripheral gangrene was made. During the etiological evaluation, Plasmodium vivax malaria was found leading to disseminated intravascular coagulation causing this complication. He was started on artesunate and lumefantrine combination therapy and he recovered completely without the requirement of amputation.

This case highlights the non-benign nature of Plasmodium vivax and its emerging complications. Also it correlates symmetrical peripheral gangrene with Plasmodium vivax malaria. It also emphasizes the importance of timely diagnosis and intervention to reduce mortality and morbidity.
