Smears of fine needle aspirates of the right pre-scapular and popliteal lymph nodes were air dried and then fixed in methanol and stained using an automated slide-stainer (Westcor Aerospray Haematology Stat Slide Stainer, Westcor, Logan, Utah) and a two-part Romanowsky stain with eosin and thiazine. Typical appearance of fungal hyphae in peripheral lymph nodes. The fungal hyphae are found in a light basophilic to eosinphilic background and surrounded by a mixture of large macrophages, small-sized lymphocytes, and moderately-degenerate neutrophils. The hyphae are 30 – 50 um long by 3-4 um wide (scale bar (10 um)), occasionally with faint septae visible, without branching, and with mixed staining of the interior.
