本次會議組織病理切片資訊：http://140.120.114.107/slidecenter.php?id=536
Case 1. CSVP 2023-3200 (NTU2023-1257, NTU GIMCP, Y. Chong and V.F.Pang)
Feline, mixed, male castrated, 10-year-old. Chronic emaciation and mouth scratching were noted since Mar. 2023. A gingival mass in M1 gingiva of right mandible was noted and the CT scan was performed. The CT results showed that the body and ramus of right mandible (molar region) presented an aggressive bone lesion. The right total hemimandibulectomy with the removal of mandibular lymph node was performed.
Morphological diagnosis:
1. Mandible & maxilla: Partially encapsulated, proliferative fibro-osseous neoplastic growth, densely cellular fibrous stroma with numerous randomly scattered ossicles. Plump spindle-shaped neoplastic cells arranged in a fascicular, storiform or whirling pattern. Indistinctly bordered cytoplasm, ovoid, elongated, fusiform nuclei, hyperchromatic with no distinct nucleolus, and mitotic count: 2 per 10 HPFsa.
2. Variable in shapes and sizes, ranging from small round or oval to largerirregularly shaped, and are calcified
3. Multinucleated giant cells are noted within the neoplasm, nearby the ossicles, suggestive of osteoclasts
4. LN: No significant lesion
Laboratory examinations: Von Kossa staining (+)
Etiological Dx.:
Ossifying fibroma, right hemimandible in a cat
Case 2. CSVP 2023-3201 (NTU2023-1659, NTU GIMCP, Y.J. Chuang and Y.C. Chang)
Rabbit, female spayed, 7-year-old. An abdominal abscess with grass was found during laparotomy in 2023, and the bacterial culture result showed Pasteurella multocida. Elevated liver index was noted, and antibiotics was prescribed for two months. A mass, measuring about 3 x 2 x 2 cm, was located at the mesentery, and adhered to the intestines during laparotomy on July 16. Surgical excision was performed
Morphological diagnosis:
Mass:
1. Enteric duplication cyst, with mild inflammation and lymphoid hyperplasia, mesenteric mass
Laboratory examinations:
IHC: MUM1, CD3 (+) for T cells; Granzyme B (+) for Large granular lymphocytic
Etiological Dx.:
Mesenteric cyst in a rabbit
Case 3. CSVP 2023-3202 (MN23012, ADDL NCYU, C.W. WU, H.C. Kuo, C.L. Chen, M.H. Chang, and D.Y. Lo)
Broiler, 16-day-old, showed clinical sign of sudden death. The accumulative mortality was 7.3 % (2,200/30,000)l.
Morphological diagnosis:
Liver: Hepatitis, necrotizing, diffuse, severe, acute, with basophilic intranuclear IBs
Laboratory examinations:
Lung: Gallibacterium anatis (+)
PCR: Liver, caecal tonsil:
Fowl adenovirus (FAdV) (+)
Nucleotide Sequencing : FAdV E strain 8b, 99%
Bursa: IBDV (-)
Etiological Dx.
Inclusion Body Hepatitis in Broilers
Case 4. CSVP 2023-3203 (WA111-242, ADDC NPUST, S.Y. Tsai, C.A. Yang, Y.H. Hsieh, and Y.C. Li)
Capybara (Hydrochoerus hydrochaeris) (水豚), 1~2-year-old, male, showed depression and emaciation since August 1, 2022, and was found dead one month later..
Morphological diagnosis:
Cholangiohepatitis, coalescing, chronic active, severe, eosinophilic granulomatous with intralesional trematode eggs, liver
Laboratory examinations:
Liver: Cox1:
egg Fasciola hepatica (+) 130–150 μm x 60–90 μm
egg Fasciola gigantica (-) 190 μm × 100 μm
Etiological Dx.
Fasciola Hepatica Infestation of Capybara (Hydrochoerus Hydrochaeris)
Case 5. CSVP 2023-3204 (2023-0355-7, NTU and ADDC-VRI, L.W. Hu, Y.C. Chuang, Y.C. Tu, S.C. Hu, F. Lee, and Y.W. Chen)
Domestic goat (Capra aegagrus hircus), male, subadult. The domestic sick goat showed emaciated. Numerous Haemonchus contortus捻轉胃蟲and cestodes were noted in the abomasum and small intestines, respectively. The mesenteric lymph nodes were significantly swollen.
Morphological diagnosis:
Small intestines: enteritis, eosinophilic and lymphoplasmacytic, diffuse, chronic, severe with nematodes and cestodes infestation
