Cаse: A 32-yeаr-оld wоmаn visited a walk-in clinic with cоmplaints of swelling in her right leg below the knee. She had recently moved to the United States from Southeast Asia in the last year to live with relatives. The examining physician found enlarged lymph nodes in her right leg. Based on her recent travel and former residence and her clinical symptoms, the physician suspected a parasitic infection and ordered thick and thin blood smears. The following objects were identified in Giemsa-stained smears, measuring about 200 µm in length. Given the following images Figures A-D below, what is your diagnosis? Based on what evidence?
