Encapsulated eumycetoma caused by Biatriospora mackinnonii.

Eumycetoma is a chronic infection due to filamentous fungi. Herein, we report a case of eumycetoma presenting as a subcutaneous encapsulated lesion on the right leg with no previous traumatic implantation. From microscopic morphological characteristics and molecular analysis, the pathogenic fungal species were identified as Biatriospora mackinnonii. Surgical excision of the entire lesion was performed to reduce the fungal load and improve antifungal therapy response.
