Cutaneous Manifestations of Malaria and Their Prognostic Windows: A Narrative Review

Abstract

Malaria is a vector-borne tropical infection caused by protozoa of the genus Plasmodium and is transmitted by the bite of an infected Anopheles mosquito. The disease is commonly characterized by fever, edema, thrombocytopenia, hypoglycemia, anemia, and myalgias; however, the infection’s cutaneous presentations are not commonly emphasized and tend to be overlooked. A literature search was conducted that focused on the various skin pathologies that malaria patients have been noted to present with using case reports and currently available literature. We describe the various skin manifestations associated with malaria, such as purpura fulminans, febrile urticaria, cutaneous leishmaniasis co-infections, urticaria infectiosum, vivax-induced severe thrombocytopenia petechiae, acral skin necrosis, and reticulated erythema, and how each of these skin manifestations may provide insight into the patient’s prognosis. Documentation and vigilance regarding these cutaneous manifestations must be emphasized as they may lead to better patient outcomes and a stronger understanding of the patient’s underlying malaria.
