Subcutaneous phaeohyphomycosis caused by Aureobasidium Pullulans in an immunocompetent carpenter

Abstract

Phaeohyphomycosis refers to uncommon infections due to a large group of heterogeneous organisms called “dematiaceous fungi”. Here, we report a rare case of subcutaneous phaeohyphomycosis in an immunocompetent carpenter, presenting as multiple verrucous and confluent papulo-nodules of the right leg, and likely due to traumatic inoculation. The pathogenic fungal species was identified as Aureobasidium pullulans, according to macroscopic and microscopic morphological characteristics of the colonies. Surgical excision of the entire lesion and adjunctive antifungal therapy was curative.
