Is it Subungual Melanoma? Fungal Melanonychia due to Phoma Glomerata

Abstract

A 32-years-old female patient referred to our clinic with melanotic color change at her right thumb nail. It was suspected from subungual melanoma. Therefore a full thickness biopsy and an excavation example was taken from the nail for the histologic and microbiologic examination. The lesion was reported as fungal melanonychia which was occured by Phoma Glomerata. As far as we know this is the first case that occured by Phoma Glomerata. Also the case could be misdiagnosed as subungual melanoma. Therefore we aimed to share this case with our colleagues.
