Successful Treatment of Disseminated Anncaliia algerae Microsporidial Infection With Combination Fumagillin and Albendazole.

Anncaliia algerae myositis is a life-threatening, emerging microsporidiosis among immunocompromised hosts. We report a case of disseminated A algerae infection in a man previously treated with alemtuzumab. Due to failure of albendazole-based therapy, fumagillin was added as a novel approach to management, with a good clinical response and patient survival.
