Scedosporium apiospermum, the anamorphic form of Pseudallescheria boydii, is a filamentous fungus present ubiquitously inhabiting water and soil (Jene-Kuen et al., 1995). It is now recognized as a medically important opportunistic fungus. Pus sample aspirated from a painless, fluctuant swelling over the anterior aspect of right forearm of a 60 year old diabetic female was processed to identify the causative agent. KOH mount revealed the presence of septate branching hyphae. Sabouraud’s Dextrose Agar with gentamicin showed white to mousy gray, cottony fluffy white mycelium. Lactophenol cotton blue mount from slide culture was positive for Scedosporium apiospermum. S.apiospermumhas drawn the attention of clinicians and microbiologists, as an emerging opportunistic pathogen in the immunocompromised patients. Microbiological diagnosis of Scedosporium species currently depends upon the culture and morphological characterization.
