Large trophozoites in blood smear of falciparum malaria: one case report

This paper reports one case of atypical falciparum malaria imported from Africa,whose blood smear contains many large trophozoites,with punctiform or massive brown pigment granules,the body shape of the plasmodium is similar to that of Plas-modium vivax and Plasmodium ovale. After the gene detection by PCR,the case was diagnosed as falciparum malaria. As large tro-phozoites were rarely seen in the peripheral blood of non-severe falciparum malaria cases,much attention should be paid to the identification of Plasmodium falciparum and other plasmodia in microscopic examinations.
