Plain-English summary
A 7-year-old male Quarter Horse was found to have a rare skin condition called mycetoma, which is a type of fungal infection that causes chronic lumps under the skin. This horse had the infection in its neck area, and it was diagnosed using various tests that looked at cells, tissue samples, and cultures. The specific fungus causing the infection was identified as Aspergillus nidulans, which is more commonly known for causing issues in a different part of the horse's body. This case is notable because it's only the second time this particular fungus has been linked to mycetoma in horses, emphasizing the need for veterinarians to consider fungal infections when they see nodules on a horse's skin. The treatment details and outcome were not provided in the abstract.
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.
