Plain-English summary
A 7-year-old male Quarter Horse was brought in with a lump on his neck that turned out to be a rare fungal infection called mycetoma. The infection was caused by a fungus known as Aspergillus nidulans, which is typically associated with other conditions in horses. After thorough testing, including examining samples from the lump, the diagnosis was confirmed. This case is notable because it highlights the need for veterinarians to consider fungal infections when diagnosing skin masses in horses.

Abstract
Mycetoma is a fungal chronic skin proliferative lesion rarely encountered in horses and often associated with fungi such as Scedosporium spp., Madurella spp., Phialophora spp., Curvularia spp., and less frequently with Aspergillus spp. A case of subcutaneous mycetoma in the cervical region in a 7-year-old male Quarter Horse, diagnosed through cytological, histological, cultural and molecular methods, is reported. Aspergillus nidulans, usually implicated in guttural pouch mycosis, was identified. This unusual case represents the second case report of mycetoma caused by Aspergillus nidulans in the horse and highlights the importance of including mycotic diseases in the differential diagnosis of nodular skin masses in equine patients.
