RESUMEN
A 54-yr-old male, who was treated by chemotherapy for gastric cancer 15 months ago, presented to Yongdong Severance Hospital, Seoul, with complaints of pain in his right eye caused by a foreign body from the ground in the previous week. He had been treated with topical and oral antibacterial in addition to antifungal agents, but did not show significant clinical improvement. After a positive corneal culture with mold, topical amphotericin B was added to the initial regimen. The mold was identified as Scedosporium apiospermum by macroscopic and microscopic morphologies and the nucleotide sequences of a fungal PCR product showing 99% homology with those of S. apiospermum (EF151349). He recovered with good results at 25 days after corneal epithelial debridement. The early diagnosis of S. apiospermum keratitis is very important for proper treatment. It is recommended that molecular diagnostic methods such as fungal PCR and sequencing be done with conventional cultures whenever a fungal infection is suspected.

A 40-year-old man who had been treated for multiple myeloma, complained of decreased visual acuity of the left eye on the 30th day of admission. The nucleotide sequences of a fungal PCR product from vitreous fluid showed 99% homology with Aspergillus fumigatus (AY373851). Aspergillus spp. was isolated from vitreous fluid culture, also. Rapid diagnosis and intervention are critical elements for the Aspergillus endophthalmitis; therefore, it would be helpful to combine the fungal PCR with conventional fungus culture for clinically indicated specimens.
