However, P. falciparum malaria can also be seen among those who have a history of visiting abroad. Here, we reported a patient with P.falciparum whose treatment was started in Sudan due to suspicion of malaria, the diagnosis and follow-up was carried out in our clinic then after. Thirty-three years old male patient was admitted to outpatient clinic with complaints of fatigue and loss of appetite. In his history it was obtained that he had worked in Sudan and had applied to the hospital with complaints of high fever, sweating and weakness. In his parasitological examination, P. falciparum was detected. Mefloquine and artesunate oral treatment were started. After taking these medicines for three days, the patient returned to Turkey and applied to our department. Anemia and thrombocytopenia were detected. Doxycycline 100 mg twice a day treatment was started orally. Since P. falciparum related malaria clinically can cause complications such as cerebral malaria, hypoglycemia, anemia, thrombocytopenia and pulmonary edema, close follow-up is necessary. In our case, the patient was put under follow-up for anemia and thrombocytopenia, and he was recovered totally without needing any extra intervention.
