Plain-English summary
A 35-year-old horse was examined after passing away, and during the examination, several fluid-filled cysts were found in the right kidney. These cysts were pushing against the normal kidney tissue and were lined with a specific type of cell that can produce mucus. The findings led to a diagnosis of renal mucus-gland cystadenomas, which are a type of tumor in the kidney. This case suggests that if similar cysts are found in a horse's kidney, this type of tumor should be considered as a possible cause.
Abstract
A 35-year-old horse was submitted to the necropsy service at the University of Kentucky Livestock Disease Diagnostic Center. At necropsy, multiple 1-4-cm-diameter cystic structures were incidentally identified unilaterally in the right renal medulla and the cortex. On histologic examination, the cystic structures compressed the normal renal architecture, were lined by tall columnar epithelium that formed occasional papillary projections, and contained large amounts of mucicarmine and periodic acid-Schiff-positive mucinous material. The masses were diagnosed as renal mucus-gland cystadenomas. This tumor should be considered as a differential diagnosis when cystic structures are identified in the equine kidney.
