[Maxillary fungal sinusitis by Zygomicetos. Report of a case in an immunocompetent patient].

We report the clinical case of a 36 years old female without significant previous history who was diagnosed with an acute maxillary sinusitis with not responding to antibiotic treatment. After her admission we asked for a CT which showed an occupation in the left maxillary sinus with a calcified area inside suggesting a mycetoma. The patient was operated by Functional Endoscopy Sinusal Surgery (FESS) plus Caldwell-Luc techniques sending the obtained sample for microbiological study, that was reported as sinusal mycosis by Zygomicetos. The postsurgical evolution was satisfactory.
