Abstract:
We describe a case of nasal myiasis due to Musca domestica in a 97-year-old Peruvian farmer with a previously undiagnosed mucocutaneous leishmaniasis. Initial attempts to remove the fly larvae using manual extraction with a toothed forceps and normal saline irrigation were unsuccessful. On subsequent nasal irrigation with ivermectin solution, the patient self-expulsed approximately 50 larvae within 15 min. He also received a course of oral ivermectin. A post-treatment CT scan revealed clear sinuses. Here, we propose that ivermectin irrigation is a simple and effective treatment for nasal myiasis.
