The authors describe a rare case of an infection of both the chromomycosis and aspergillosis of the maxillary sinus in an immunocompetent 72-year-old female who presented with progressive visual loss and dull aching pain of the left eye. Sinuscopy of the left maxillary sinus showed swelling of the mucosa with claylike materials. Biopsy from the left maxillary sinus showed the typically characteristic morphology of
chromomycosis and culture from sinus tissue which yielded Aspergillus. The patient responded to a combination therapy of surgical excision and antifungal agent.
