Tracheal mucormycosis pneumonia: a rare clinical presentation.

This article reports an unusual case of tracheal mucormycosis following H1N1 pneumonia and reviews previously reported cases. A 40-y-old female with a 5-y history of diabetes mellitus, adequately controlled by oral hypoglycemic agents, developed tracheal mucormycosis after successful treatment for H1N1 pneumonia. The condition was diagnosed during workup for decannulation due to subglottic and upper tracheal obstruction by necrotic chewing gum-like tissue and cartilage. The patient was managed successfully by treatment with amphotericin B and surgical intervention in the form of laryngofissure and Montgomery tube placement. A review of the literature revealed only 5 previously reported cases of tracheal mucormycosis. A high degree of suspicion, early endoscopy and biopsy, histopathological evidence of the infection, and early institution of therapy are the keys to successful outcome.
