A 28-year-old soldier stationed in the Middle East notices a 0.5-cm papule on his right forearm. After a week, it becomes a 1-cm nodule with a central depression and ulcerates over the next month. Physical examination reveals a 2-cm ulcerated lesion with an indurated border, and three smaller satellite lesions on the forearm, right axillary lymphadenopathy. No hepatosplenomegaly is noted. Laboratory studies show hemoglobin, 14.2 g/dL; hematocrit, 42.5%; platelet count, 235,300/mm3; and WBC count, 6450/mm. Infection with which of the following organisms is the most likely cause for the skin ulcers? Answers A E A Borrelia burgdorferi B Brugia malayi C Leishmania major D Mycobacterium leprae E Trypanosoma cruzi
