Chronic Invasive Rhinosinusites by Conidiobolus Coronatus

Abstract

Chronic invasive fungal rhinosinusitis is a rare and potentially aggressive infection, characterized by nasal obstruction due to the presence of fungal hyphae infiltrating the mucosa, submucosa, bone, or blood vessels of the paranasal sinuses, facial pain and hyposmia. Conidiobolus is a very rare cause of chronic invasive fungal rhinosinusitis. This fungus predominates in tropical forests and usually is not present in Europe. We aim to present the first case of chronic invasive fungal rhinosinusitis due to Conidiobolus diagnosed in a Portuguese patient. We present a Caucasian 65 years old male patient with progressive nasal obstruction, bilateral frontal headache and a hyposmia with 8 months of evolution. He was diagnosed a chronic invasive rhinosinusitis associated with hypertrophied inferior turbines and ulcerative nasal mucositis. The identification of Conidiobolus was performed in samples from surgical excision biopsies, by macroscopic observation of the colony, microscopic observation of the mycelium and molecular biology techniques. The patient was treated using liposomal B amphotericin and followed up for 3 years without intercurrences.Chronic invasive fungal rhinosinusitis by conidiobolus is not restricted to tropical forests anymore. European physicians must be aware of this possibility. Diagnosis is only possible by strong suspicious and conjugated efforts between surgeons and pathologists.Chronic invasive fungal rhinosinusitis is a rare and potentially aggressive infection, characterized by nasal obstruction due to the presence of fungal hyphae infiltrating the mucosa, submucosa, bone, or blood vessels of the paranasal sinuses, facial pain and hyposmia.

Rinosinusite crónica fúngica invasiva é uma infeção rara e potencialmente agressiva, caracterizada por obstrução nasal, dor facial e hipósmia, secundárias à infiltração da mucosa, submucosa, ossos ou vasos sanguíneos dos seios paranasais. Conidiobolus é uma etiologia muito rara de Rinosinusite Crónica Fúngica Invasiva, predominando em zonas de florestas tropicas, não sendo encontrado normalmente na Europa.Pretendemos apresentar o primeiro caso de Rinosinusite Crónica Fúngica Invasiva por Conidiobolus diagnosticada num doente português.Apresentamos um doente do sexo masculino, 65 anos de idade, com obstrução nasal progressiva, cefaleia frontal bilateral e hiposmia com 8 meses de evolução. Foi diagnosticada uma rinosinusite crónica fúngica invasiva com hipertrofia dos cornetos inferiores e mucosite nasal ulcerativa. A identificação fúngica foi possível através de biopsias realizadas cirurgicamente, observação macroscópica de colónias, observação microscópica de micelas e técnicas de biologia molecular. O doente foi tratado com Anfotericina B lipossómica, tendo sido seguido durante 3 anos sem intercorrências.A Rinosinusite Crónica Fúngica Invasiva por Conidiobolus já não se encontra restrita às florestas tropicais, devendo os clínicos europeus estar atentos a esta etiologia. O diagnóstico é apenas possível através de fortes suspeições conjugadas com o trabalho conjunto de cirurgiões e patologistas.Rinosinusite crónica fúngica invasiva é uma infeção rara e potencialmente agressiva, caracterizada por obstrução nasal, dor facial e hipósmia, secundárias à infiltração da mucosa, submucosa, ossos ou vasos sanguíneos dos seios paranasais.
