Plain-English summary
A 23-year-old male Quarter horse was found to have a condition called mucinous hyperplasia, which means there was an unusual growth of mucus-producing cells in his right kidney and ureter. The right kidney was swollen and filled with thick, yellowish-green mucus, which was pressing on the surrounding tissue. There were also similar growths found in the lining of the urethra. This case is notable because it appears to be the first time this condition has been reported in horses. The outcome of the treatment for this condition was not mentioned.
Abstract
A case of mucinous hyperplasia in the right renal pelvis and ureter is reported in a 23-year-old, male, Quarter horse. The affected right renal pelvis was markedly distended and filled with inspissated yellowish-green mucous material compressing the adjacent cortical and medullary parenchyma. Multiple, similar masses were present protruding from the right urethral mucosa. Histologically, the masses were characterized by a cystic glandular and papillary hyperplasia of the mucosa of the renal pelvis and ureter. This is believed to be the first reported case in an equine species.
