First report of Tritirachium oryzae infection of human scalp.

The natural habitat of Tritirachium oryzae is soil and decaying plant material. It is also an insect pathogen. As a human pathogen, it has been reported as a cause of corneal ulcers and otomycosis. The case of a 4-year-old infant is reported with Tritirachium oryzae infection of the scalp. Diagnosis was established by direct mycological study and culture that showed Tritirachium oryzae as the only agent in a pure culture. The topical treatment involved an antifungal medication to a complete cure. We report the first case of scalp dermatomycosis due to Tritirachium oryzae infection, illustrating a novel clinical manifestation.
