Subcutaneous infection caused by Blastoschizomyces capitatus post allogeneic hematopoietic transplant and its successful treatment with voriconazole.

ABSTRACT

We describe a 33-year-old man with relapsed acute myelogenous leukemia who developed subcutaneous nodules >6 months after allogeneic hematopoietic stem cell transplant. These nodules were caused by Blastoschizomyces capitatus. The lesions progressed after treatment with a posaconazole suspension. The lesions resolved after switching to voriconazole, which was given for 21 weeks. B. capitatus is a rare infection affecting immunocompromised patients, which responds to azoles.
