Vasoinvasive fungal infection. The branching at 90 degrees suggest mucormycosis (zygomycoses family).

Aspergillosis vs mucormicosis. I  thought branching was more like 45 degrees and the hyphae to be thin so favour more aspergillus. Nevertheless, the differential between these two entities is hard only based on histology.

Hyphae are septated, so I tend to interpret them as Aspergillus within the lumen of thrombosed dermal blood vessels.

Sorry for the delayed history.  This is a 36 year-old male with AML.  This biopsy is from the left forearm.

Fusarium and Aspergillus can be hard to tell apart by histology.  This is Fusarium.
