Canine Pyogranulomatous Dermatitis Caused by Nocardia-subspecies InfectionHiroshi UENO*†, Tsuyoshi KADOSAWA, Kenji OCHIAI,
SUMMARY Cytological examination showed a large subcutaneous mass on the right lateral elbow of a 5-year-old
boxer dog to be pyogranulomatous dermatitis. The entire mass was excised. Because histopathological examination
revealed fungal hyphae of Nocardia, we diagnosed pyogranulomatous dermatitis caused by Nocardia subspecies.
Long-term adjunctive antibiotic therapy was applied. The large open wound was washed frequently and treated
with chitosan, which has incarnant effects. In addition, the wound was covered with chitin-coating dressing
as an epithelialization accelerator. On the 60th day, the wound had been reduced about one-tenth from
its original size and on the 74th day one-fiftieth. On the 88th day, it was fully closed. After 18 months,
there has been no recurrence of the disease.
