Cholangiocarcinoma is a malignant tumour of bile duct epithelial cells, an uncommon primary hepatic neoplasm in cattle. A 9‐year‐old Simmental cow presented with watery diarrhoea, crusty skin lesions, loss of appetite and hepatomegaly. Suspecting severe liver disease, the cow was euthanased due to poor prognosis. During gross postmortem examination, large numbers of multifocal to coalescing nodules often with soft necrotic centres ranging from miliary to 7 cm in size were present in the liver, lung, mesentery, peritoneum and lymph nodes. These features were suggestive of bovine tuberculosis. However, direct tissue smears stained by Ziehl Neelsen stain were negative for the presence of acid‐fast bacteria, and subsequent histopathological and immunohistochemical investigations confirmed the presence of metastasizing cholangiocarcinoma. This case reminds clinicians and pathologists to keep an open mind during the diagnostic process and serves to highlight the value of histopathology in diagnosing seemingly characteristic gross lesions.

A 3‐year‐old, 255 kg, mixed breed beef cow has an abortion at the last trimester of gestation, approximately 8 months. The cow was from a 1200‐hectare farm, with 1200 animals. The farm owner reported a total of 13 abortions between June and September 2022, all of them in the last trimester of gestation. Additional serological screening for Leptospira was performed in 40 cows from the herd by microscopic agglutination test with seropositive animals to serovars Icterohaemorrhagiae. Gross postmortem examination yielded icterus, pleural and peritoneal effusions. Histopathological findings were lymphoplasmacytic interstitial pneumonia and nephritis, with intraluminal spirochetes within the renal tubules, hepatic necrosis, and cholestasis. PCR on a fresh tissue pool was positive for Leptospira spp. (LipL32). Leptospirosis is a zoonotic disease, caused by the infection of the bacterial spirochetes belonging to the genus Leptospira spp. Serovars Pomona and Icterohaemorrhagiae cause acute systemic leptospirosis in cattle after incidental infections due to poor husbandry conditions and cause abortion loss in cattle in occasional outbreaks.

We present a case of a 3‐year‐old, male Border Collie with severe hip dysplasia and osteoarthritis undergoing total hip replacement, notably having a history of a previous hip surgery with inadequate epidural analgesia. Our objective was to evaluate epidural efficacy before surgery using nociceptive threshold measurement. Nociceptive thresholds were measured with transdermal electrical stimulation via the Dolosys Pain Tracker device. The dog received epidural ropivacaine and morphine, resulting in a cessation of withdrawal response and electromyographic activity. This effect was confirmed under anaesthesia. Postoperatively, the dog recovered without relevant complications. In conclusion, nociceptive threshold measurement using the Dolosys Pain Tracker device allowed immediate confirmation of epidural efficacy, reducing the risk of intraoperative analgesic inadequacy. This approach may enhance surgical pain management in challenging cases.

A 10‐year‐old, male, farm‐based springer spaniel that presented with subacute progressive left‐sided central vestibular signs was diagnosed with meningoencephalitis of unknown origin. The patient received prednisolone (2 mg/kg/day orally), ciclosporin (5 mg/kg orally twice a day) and a single infusion of cytarabine (200 mg/m2). Six weeks later, neurological signs had resolved, but multiple cutaneous nodules developed on the limbs, trunk and face. Lesions discharged a dark purulent material without tissue grains. A ‘filamentous fungus’ was isolated, but discarded without identification. Aspirates from nodules showed pigmented, septate fungal hyphae, and culture of aspirates yielded Trematosphaeria grisea. Itraconazole (5 mg/kg once a day) and gradual tapering of immunosuppressive drugs led to resolution of nodular lesions over 4 months without neurological relapse. A fungal granuloma developed transiently 8 months after starting itraconazole. Immunosuppressive drugs were stopped 15 months after introduction without neurological relapse. Itraconazole was withdrawn 8 weeks later, 5 months after last relapse of skin disease.

A 6‐year‐old, male, neutered, brown eyed labrador retriever was presented with an intraocular pale pink mass in the left eye. Enucleation of the globe was performed, and the mass was submitted for histopathology. Histology and immunohistochemistry confirmed the mass as a malignant nerve sheath tumour. There was no evidence of mass recurrence, and general and neurological examination remained normal at 9‐month follow‐up. While the majority of intraocular neoplasms are benign, a malignant neoplasm must be considered in all cases of intraocular mass. Differentiation between benign and malignant intraocular neoplasms is challenging and often requires enucleation with histopathology to confirm diagnosis. Tumour staging should be considered in the event of a malignant nerve sheath tumour. Finally, uveal malignant nerve sheath tumour should not only be considered in blue eyed dogs, but also in brown eyed dogs as in the present case.

A 3‐month‐old, male, entire, domestic shorthair kitten underwent investigations for stranguria and haematuria, and was diagnosed with a urinary tract infection secondary to a suspected extramural vesicourachal diverticulum. Lower urinary tract signs resolved with a 14‐day course of amoxicillin clavulanate. Three months later, the kitten re‐presented for investigation of acute onset ventral abdominal discomfort and bruising. On presentation, clinical examination revealed omphalitis and subcutaneous bruising, with no evidence of an umbilical stoma. Ultrasonography demonstrated a patent urachus communicating with the subcutaneous tissue space, resulting in accumulation of urine at the level of the umbilicus. A ventral midline coeliotomy was performed to allow resection of the urachal remnant, including a partial cystectomy. The cat was urinating normally within 10 hours postoperatively, and the wound healed without complication. No postoperative complications or recurrent lower urinary tract signs were reported at follow‐up (312 days).

A 12‐year‐old, male, entire Labrador retriever was presented to its primary care practice with a history of vomiting. A soft tissue mass was identified within the soft palate. Cytology from a fine‐needle aspirate revealed atypical mast cells, consistent with a mast cell tumour. Initial staging included complete blood count, serum biochemistry, serum electrolyte assay, thoracic, abdominal and cervical radiographs, computed tomography of the head and neck, and ultrasound‐guided aspirates of the retropharyngeal lymph nodes, liver and spleen. No evidence of nodal or distant metastasis was identified, and a diagnosis of primary soft palatal mast cell tumour was made. The dog underwent staphylectomy followed by adjunctive chemotherapy. Repeat staging was performed, which did not identify any evidence of metastasis. The dog died 22 months after initial presentation from an unknown cause.

Shoulder arthrodesis is a recognised procedure for incapacitating shoulder conditions in dogs in cases where traditional surgical or medical interventions are not feasible. However, the use of shoulder arthrodesis in the feline patient has not been described. This case report details the novel use of shoulder arthrodesis in a 10‐month‐old cat with a chronic right forelimb lameness attributed to humeral head dysplasia. Surgical stabilisation of the right shoulder arthrodesis was achieved with two 2.4 mm Synthes locking compression plates and two 2.4 mm inter‐fragmentary positional screws. Short‐term follow‐up indicated adequate bone healing with good alignment and implant integrity. Subsequent long‐term phone follow‐up 22 months after surgery revealed a successful outcome with no visible stiffness and only a mechanical lameness. This result underscores the viability of shoulder arthrodesis as a potential option for feline patients necessitating shoulder salvage procedures.

A 2‐year‐2‐month‐old, male Syrian hamster (Mesocricetus auratus) was referred for ulceration and encrustation of the abdominal skin. The affected skin was surgically excised. Histological examination revealed changes consistent with an epitheliotropic T‐cell lymphoma. Two months after the surgery, no clinical signs of disease or tumour recurrence were evident. When patients with consistent clinical signs are presented, cutaneous neoplasia should be considered, especially in older animals. Surgical excision may offer short‐term remission for epitheliotropic lymphoma.
一只 2 岁 2 个月大的雄性叙利亚仓鼠（Mesocricetus auratus）因腹部皮肤溃疡和结壳而被转诊。患处皮肤经手术切除。组织学检查显示其变化与上皮细胞性 T 细胞淋巴瘤一致。手术两个月后，没有出现明显的临床症状或肿瘤复发。当患者出现一致的临床症状时，应考虑皮肤肿瘤，尤其是年龄较大的动物。手术切除可在短期内缓解上皮细胞淋巴瘤。
