Plain-English summary
A 4-year-old male Great Dane developed severe swelling in his scrotum, which led to surgery to remove his testes and epididymides. The examination revealed hard tissue and small abscesses in the epididymides, and tests showed an infection caused by a type of yeast called Rhodotorula glutinis. After the surgery, the dog was diagnosed with granulomatous epididymitis, a condition related to this infection. The treatment involved the surgical removal of the affected tissues, which was necessary to address the severe symptoms.

Abstract
A 4-year-old, male Great Dane dog developed severe swelling of the scrotum on 9 December 1991, and the testes and epididymides were removed surgically on 12 December 1992. The cut surface of the epididymides consisted of hard connective tissue and several small abcesses with slight hemorrhage. Histopathologically, the seminiferous tubules in the testes had only a few spermatogenic cells, but Sertoli cells were well preserved. Both epididymides consisted entirely of a proliferation of fibrous connective tissue, and only a few ducts deferens containing cell debris, neutrophils, and macrophages in the lumina were present. In all lesions of the epididymides, the macrophages contained periodic acid-Schiff- and Grocott's silver-positive round granules, 5-8 microns in diameter. Microbiologically, smooth salmon-pink colonies consisting of ovoidal yeast, about 10 microns in diameter, were isolated from the samples of epididymides but not from those of the testes. The isolated yeast had microbiological characteristics of Rhodotorula glutinis. From these observations, we diagnosed the present case as granulomatous epididymitis due to Rhodotorula infection.
