Case 1. CSVP 2026-3308 (NTU2025-1801A, GIMCP, Y.C. Liu, W.H. Huang, Y.C. Chang, and H.W. Chang)
Eland (Taurotragus oryx), female, 6.3-year-old. The patient exhibited anorexia and progressive emaciation in early October. Two ulcerative, firm lesions on the tongue were identified under anesthesia, and biopsy results revealed pyogranulomatous glossitis. Despite supportive management, the clinical condition continued to deteriorate, and euthanasia was ultimately performed.
Morphological diagnosis:
Pneumonia, necrotizing, fibrotic, and granulomatous, chronic, multifocal, severe, with intralesional fungal hyphae, severe and diffuse edema, and emphysema, lung
Nephritis, necrotizing, fibrotic, and granulomatous, chronic, multifocal, severe, with intralesional fungal hyphae and interstitial fibrosis, bilateral kidney
Glossitis, necrotizing, fibrotic, and granulomatous, chronic, multifocal, severe, with intralesional fungal hyphae, tongue
Rumenitis, necrotizing, fibrotic, and granulomatous, chronic, focal, severe, with intralesional fungal hyphae, rumen
Reticulitis, necrotizing, fibrotic, and granulomatous, chronic, focal, severe, with intralesional fungal hyphae, reticulum
Abomasitis, necrotizing, fibrotic, and granulomatous, chronic, focal, severe, with intralesional fungal hyphae, abomasum
Lab. examination :
GMS stain: pseudohyphae/hyphae (+); acid fast stain: (-);
Fungal culture - Lung mass: Debaryomyces spp. 德巴利酵母屬
Dx. : Systemic mycosis in an Eland(Taurotragus oryx)

Rabbit, intact female, 5-year-old. The owner reported intermittent episodes of hematuria over the past year. Imaging studies identified an abdominal mass suspected to be of uterine origin, with no evidence of metastasis. An ovariohysterectomy was subsequently performed.
.Morphological diagnosis:
Uterus: Adenocarinoma, endometria, neoplastic glandular proliferation, tubular or acinar forms, marked cellular atypia with high mitotic index.
Lab. examination :
Dx: Uterine adenocarcinoma in a rabbit

Spleen: Amyloidosis, diffuse, marked
Kidney: Amyloidosis, diffuse, moderate, with tubular epithelial degeneration
Foot pad: Pododermatitis, ulcerative, locally extensive, chronic active, severe

Mare, 27-year-old, presented with recurrence of multiple vulvar masses, ventral edema, and right mammary gland enlargement one month after enrollment in an exploratory clinical trial program. The horse die one week after ventral edema was noted. At necropsy, multiple masses were identified involving the mammary gland, inguinal and mesenteric lymph nodes, and pulmonary parenchyma.
Morphological diagnosis:
Vulvar: tumor cells breached the epidermal BM, arranged in trabecular- or island-like patterns, no distinct boundary with the surrounding normal tissue, highly invasive. abundant eosinophilic keratin deposits, characteristic eosinophilic keratin pearls, polygonal shaped, pale-staining nuclei, 1-3 nucleoli, mitotic figures, intravascular tumor emboli, inguinal LN¸ acantholytic subtype.
Lab. examination :
metastatic vulvar squamous cell carcinoma grade IV, acantholytic subtype
Dx: Metastatic Vulvar Squamous Cell Carcinoma in a Mare
