Plain-English summary
A 13-year-old Standardbred stallion had a long-term problem with a growth in his nose that caused a thick, pus-like discharge and made it hard for him to breathe. The growth was identified as a cryptococcal nasal granuloma, which is a type of infection caused by a fungus. Although the stallion did not receive any treatment for this condition, he was able to breed successfully for two seasons before he was put down 26 months later. Over time, the growth got larger and took up almost all of the left side of his nasal cavity and nearby sinuses. There were also signs that the infection had spread to other parts of his body, including his intestines and lungs.
Abstract
A 13-year-old Standardbred stallion presented with a unilateral mucopurulent nasal discharge and airway obstruction was found to have an extensive cryptococcal nasal granuloma. Treatment was not attempted. The stallion was destroyed 26 months later having completed 2 successful breeding seasons. The granuloma had gradually increased in size and almost completely occupied the left nasal cavity and paranasal sinuses. It was characterised histologically by fibrous and myxomatous tissue and masses of yeasts. A cryptococcal granuloma found within the wall of the jejunum could represent evidence of dissemination, and organisms were seen within alveoli, bronchioles and the intestinal lumen.
