Ulocladium has never been associated with allergic fungal sinusitis but it was identified as an etiological agent of AFS in a 35 year old immunocompetent female patient presenting with chronic nasal obstruction of several months duration to our hospital. The patient underwent FESS and the excised polyps revealed Ulocladium as the causative fungal agent. https://ijm.tums.ac.ir/index.php/ijm/article/view/54 https://ijm.tums.ac.ir/index.php/ijm/article/download/54/54
