A female raccoon dog (Nyctereutes procyonoides) captured September 1992 in Nara prefecture, Japan, suffering from swollen joints of all four limbs was necropsied. Radiographically, there was a shadow in the right pulmonary caudal lobe and periosteal bone formation around several joints. Microscopically, there was extensive edema, along with one large and many small pyogranulomatous nodules and purulent bronchitis in the right lobe and left caudal lobe of the lungs. There were intermingled branching filamentous bacteria in the lesion, which stained positively with Warthin-Starry, Grocott, and Gram stains, and partially with periodic acid Schiff and Ziehl-Neelsen stains. Extensive exostosis with coralloid trabeculation had developed bilaterally at the carpal, stifle and hock joints in the surrounding well vascularized loose connective tissue. Degeneration of articular cartilage and villous proliferation of synovial membranes were apparent. This is the first report of hypertrophic pulmonary osteoarthropathy in the raccoon dog.
1992年9月在日本奈良县捕获了一只雌性貉（Nyctereutes procyonoides），它四肢关节肿胀，随后对其进行了尸检。X光检查显示，右肺尾叶有阴影，多个关节周围有骨膜骨形成。显微镜下，右肺叶和左肺尾叶有广泛水肿，伴有一个大的和许多小的脓性肉芽肿结节以及脓性支气管炎。病变中有交织的分支丝状细菌，经Warthin-Starry、Grocott和革兰氏染色呈阳性，部分经过碘酸希夫染色和齐尔-尼尔森染色呈阳性。在腕关节、膝关节和跗关节两侧周围血管丰富的疏松结缔组织中出现了广泛的外生性骨疣，并伴有珊瑚状小梁形成。关节软骨变性和滑膜绒毛增生明显。这是关于貉肥大性肺性骨关节病的首次报道。
