Nasal polyp due to Trichoderma harzianum-A case report.

We describe here a case of nasal polyp of the left nose due to Trichoderma harzianum, an emerging fungal infection with an often fatal outcome. Culture showed growth of T. harzianum which was identified by cultural characteristics, microscopic morphology, and molecular methods. The patient was initially treated with a combination of surgical removal of the polyp and oral antibiotics. This case points out that careful scrutiny of nasal polyp is required to ensure accurate diagnosis and appropriate management of cases without recurrence.
