Cutaneous nocardiosis associated with insect bites.
We report the first case of cutaneous nocardiosis associated with insect bites. The patient received these insect bites while camping a few days before he presented to the emergency room. The patient was a healthy twenty-six-year-old man, who was asplenic as a result of a motor vehicle accident. He presented to the emergency room with fever, multiple insect bites to his left lower extremity with pustules, lymphangitis, and left inguinal adenopathy. He was hospitalized but his condition failed to improve despite treatment with intravenous nafcillin for three days. Wound and blood cultures subsequently grew Nocardia brasiliensis. Treatment with intravenous amikacin (5 mg/kg every eight hours) was instituted along with oral trimethoprim-sulfamethoxazole double strength twice a day. The patient recovered with minimal scarring of the extremity. The amikacin was stopped after seven days and the patient was discharged to receive oral trimethoprim-sulfamethoxazole. This disease should be kept in mind when cutaneous infections do not respond to standard antibiotics, especially in the southwestern United States.
