At higher magnification the zone of palisaded histiocytes forms a relatively pure infiltrate with a paucity of other cell types. The adjacent dermis is not significantly involved by infiltrates of lymphocytes, plasma cells, or neutrophils. The green arrows point to linear structures with represent fungal organisms. Numerous organisms are represented. Some near the margin of the defect are poorly stained and probably are dead.
Some form pseudohyphae and along the pseudohyphae there are bulbous expansions.
Bulbous expansions of branching septate hyphae are represented. Some hyphae show branching at a wide angle. There is pleomorphism. The pleomorphic quality of the fungal organism is a prominent feature. Click on your browser's 'Back' button to return to the previous page.
