Rare indolent zygomycosis caused by subcutaneous Saksenaea vasiformis infection

We report an immunocompetent male child with chronic, indolent subcutaneous limb infection akin to basidiobolomycosis, but was shown by PCR method to be caused by a mucoralean fungus Saksenaea vasiformis. Treatment with oral potassium iodide solution was effective. This finding highlights the consideration of treatment decision according to the phenotypic severity as opposed to species identified.
