All of the following are GMS and PAS positive
- Candidiasis: pseudohyphae and budding yeasts
- Aspergillosis: septate, true hypae with acute angle branding
- Mucormycosis: non-septate, true hyphae, broad, ribbon-like, with
wide angle branching
- Histoplasmosis: granulomatous inflammation caused by small
budding yeasts (3-5 microns). Grossly, tree-barking appearance of
granuloma is characteristic
- Blastomycosis: mixed acute and granulomatous inflammation caused
by large budding yeasts, thick-walled with broad-based bud
- Coccidioidomycosis: granulomatous inflammation caused by variable
sized daughter cysts within large cyst wall. Thick walled spherule w/ numerous endospores
- Cryptococcosis: minimal or no inflammation, budding yeasts with
