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.
胆管癌是胆管上皮细胞的恶性肿瘤,是牛不常见的原发性肝肿瘤。一头 9 岁的西门塔尔牛出现水样腹泻、皮肤结痂、食欲不振和肝肿大。由于怀疑患有严重肝病,该牛因预后不良而被安乐术。在尸体解剖时,在肝脏、肺、肠系膜、腹膜和淋巴结中发现了大量多灶性至凝聚性结节,通常伴有软性坏死中心,大小从米粒至 7 厘米不等。这些特征表明是牛结核病。然而,经齐氏染色法(Ziehl Neelsen stain)染色的直接组织涂片显示,耐酸细菌呈阴性,随后的组织病理学和免疫组化检查证实了转移性胆管癌的存在。这个病例提醒临床医生和病理学家在诊断过程中要保持开放的心态,并突出了组织病理学在诊断看似特征性的大体病变方面的价值。

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.
一头 3 岁、体重 255 千克的混种肉牛在妊娠最后三个月(约 8 个月)发生流产。该奶牛来自一个占地 1200 公顷、饲养 1200 头牲畜的农场。据农场主报告,在 2022 年 6 月至 9 月期间,共有 13 次流产,均发生在妊娠的最后三个月。通过显微凝集试验对该牛群中的 40 头奶牛进行了钩端螺旋体血清学筛查,结果显示 Icterohaemorrhagiae 血清阳性。尸检结果为黄疸、胸腔积液和腹腔积液。组织病理学检查结果为淋巴浆细胞性间质性肺炎和肾炎,肾小管内有腔内螺旋体,肝坏死和胆汁淤积。新鲜组织池的 PCR 检测结果显示钩端螺旋体属(LipL32)呈阳性。钩端螺旋体病是一种人畜共患疾病,由钩端螺旋体属的细菌螺旋体感染引起。由于饲养条件差,波莫纳血清型和伊克曲海默氏血清型在偶然感染后会引起牛的急性全身性钩端螺旋体病,偶尔爆发时会导致牛流产。

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.
我们介绍了一例患有严重髋关节发育不良和骨关节炎的 3 岁雄性边境牧羊犬接受全髋关节置换术的病例,值得注意的是,该犬之前曾接受过硬膜外镇痛不足的髋关节手术。我们的目的是在手术前使用痛觉阈值测量法评估硬膜外镇痛效果。我们通过 Dolosys 疼痛追踪器测量了经皮电刺激的痛觉阈值。狗接受硬膜外罗哌卡因和吗啡治疗后,戒断反应和肌电活动均已停止。这一效果在麻醉状态下得到了证实。术后,该犬恢复良好,未出现相关并发症。总之,使用 Dolosys 疼痛跟踪仪测量痛觉阈值可以立即确认硬膜外麻醉的疗效,降低术中镇痛不足的风险。这种方法可以加强对具有挑战性病例的手术疼痛管理。

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.
一只 10 岁的雄性农场春犬出现亚急性进行性左侧中央前庭症状,被诊断为不明原因的脑膜脑炎。患者接受了泼尼松龙(2 毫克/千克/天,口服)、环孢素(5 毫克/千克,口服,一天两次)和一次阿糖胞苷输注(200 毫克/平方米)。六周后,神经系统症状缓解,但四肢、躯干和面部出现多发性皮肤结节。病变部位排出深色脓性物质,没有组织颗粒。分离出一种 "丝状真菌",但未经鉴定就丢弃了。从结节中抽出的吸液显示出色素沉着、有隔膜的真菌菌丝,对吸液进行培养后发现了灰褐斑曲霉(Trematosphaeria grisea)。伊曲康唑(5 毫克/千克,每天一次)和免疫抑制剂的逐渐减量导致结节性病变在 4 个月内消退,神经系统没有复发。在开始使用伊曲康唑 8 个月后,出现了短暂的真菌肉芽肿。使用免疫抑制剂 15 个月后停药,神经系统未复发。8 周后,即皮肤病最后一次复发 5 个月后,停用了伊曲康唑。

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.
患者是一只 6 岁的雄性棕色眼睛拉布拉多猎犬,已绝育,左眼眼内有一个淡粉色肿块。医生为它进行了眼球摘除术,并将肿块送去进行组织病理学检查。组织学和免疫组化证实肿块为恶性神经鞘瘤。没有肿块复发的迹象,随访9个月后,全身检查和神经系统检查仍保持正常。虽然大多数眼内肿瘤是良性的,但所有眼内肿块病例都必须考虑恶性肿瘤。眼内良性肿瘤和恶性肿瘤之间的鉴别具有挑战性,通常需要进行眼球摘除术和组织病理学检查才能确诊。如果是恶性神经鞘瘤,则应考虑肿瘤分期。最后,葡萄膜恶性神经鞘瘤不仅适用于蓝眼犬,也适用于本例中的棕色眼犬。

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).
一只 3 个月大的雄性全毛短毛猫因绞痛尿和血尿接受了检查,并被诊断为疑似膀胱尿道外憩室引起的继发性尿路感染。服用阿莫西林克拉维酸钾 14 天后,下尿路症状消失。三个月后,小猫因急性腹部不适和瘀伤再次就诊。就诊时,临床检查发现它患有脐炎和皮下瘀伤,但没有发现脐部造口。超声波检查显示,尿道与皮下组织间隙相通,导致尿液积聚在脐部水平。医生为它进行了腹中线联合开腹手术,以便切除尿道残端,包括部分膀胱切除术。猫咪在术后 10 小时内排尿正常,伤口愈合,没有出现并发症。术后随访(312 天)时,没有发现术后并发症或复发的下尿路症状。

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.
一只 12 岁的雄性拉布拉多猎犬因呕吐前往初级保健诊所就诊。在软腭内发现了一个软组织肿块。细针穿刺细胞学检查发现了非典型肥大细胞,与肥大细胞瘤相符。初步分期检查包括全血细胞计数、血清生化、血清电解质测定、胸、腹、颈部X光片、头颈部计算机断层扫描以及超声引导下的咽后淋巴结、肝脏和脾脏抽吸。没有发现结节或远处转移的迹象,诊断为原发性软腭肥大细胞瘤。该犬接受了缝合切除术,随后接受了辅助化疗。再次进行了分期,没有发现任何转移迹象。该犬在初次发病 22 个月后死亡,死因不明。

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.
肩关节置换术是一种公认的治疗方法,适用于无法进行传统手术或药物治疗的犬类肩部残疾病症。然而,肩关节置换术在猫科动物患者中的应用尚未见报道。本病例报告详细介绍了肩关节置换术在一只因肱骨头发育不良导致右前肢慢性跛行的 10 个月大猫咪身上的新应用。手术使用两块 2.4 毫米的 Synthes 锁定压缩板和两颗 2.4 毫米的节间定位螺钉稳定了右肩关节。短期随访显示骨愈合充分,对位良好,植入物完整。术后 22 个月的长期电话随访显示,手术效果良好,无明显僵硬,仅有机械性跛行。这一结果凸显了肩关节置换术的可行性,是需要进行肩关节挽救手术的猫科动物患者的潜在选择。

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.","PeriodicalId":23496,"journal":{"name":"Veterinary Record Case Reports","volume":"212 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142268333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Epitheliotropic T‐cell lymphoma in a Syrian hamster (Mesocricetus auratus) 一只叙利亚仓鼠(Mesocricetus auratus)的上皮细胞性 T 细胞淋巴瘤

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。
