Invasive paranasal mucormycosis with peripheral eosinophilia in an immunocompetent patient.

ABSTRACT

A 53-year-old healthy patient was admitted with unilateral nasal obstruction of one month duration which was suspected to be a malignancy because of mass-like finding on radiology and peripheral eosinophilia. The biopsy of the involved sinus showed tissue invasion by aseptate hyphae suggestive of a zygomycete and tissue infiltration of eosinophilia. He was diagnosed as invasive paranasal mucomycosis and treated with complete endoscopic sinus surgery and amphotericin B deoxycholate. Paranasal symptoms with peripheral eosinophilia might be a presentation of invasive fungal sinusitis.
