Abstract
Reports of renal neoplasia are rare in neotropical wildcats. Ocelots (Leopardus pardalis) are medium-sized wildcats living in America's tropical forests. A 12-year-old captive ocelot was diagnosed with a renal mass occupying approximately 25% of the total right kidney volume. The tissue was stained with routine hematoxylin and eosin (H&E) and periodic acid-Schiff (PAS). Immunohistochemistry with the following markers was performed: cytokeratin (CK) AE1/AE3, CK19, CK 7, CD10, vimentin, Melan A, HMB45, Pax-8, and Wilms' tumor 1 (WT1). Histopathology revealed a well-differentiated epithelial tubular neoplasia with less than one mitotic figure per 2.37mm2 field. Vimentin and Pax-8 were the only positive markers. Immunohistochemically, neoplasia was diagnosed as a renal adenoma. Renal adenomas are seldom reported in neotropical wildcats. Reports on wild species are valuable for properly establishing a clinical prognosis for captive species. To the best of our knowledge, this is the first report that provides detailed microscopic and immunohistochemical descriptions of renal adenoma in a captive ocelot.

Clinical outcomes in cats with renal carcinoma undergoing nephrectomy: A retrospective study. Vet Comp Oncol 2023; 21:587-594. [PMID: 37464904 DOI: 10.1111/vco.12921] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Revised: 06/28/2023] [Accepted: 06/30/2023] [Indexed: 07/20/2023]
Abstract
Renal carcinomas (RC) are uncommonly encountered in feline medicine. Limited information regarding clinical presentation and postoperative outcomes is available. The purpose of this multi-institutional, retrospective study was to describe the presenting features and clinical outcomes of cats with RC undergoing nephrectomy. Thirty-six client-owned cats were included. Medical records from participating institutions were searched to identify cats that had a histopathologic diagnosis of RC and underwent nephrectomy from January 2001 to October 2021. The most common presenting complaints were weight loss (36.1%) and hyporexia (30.6%). Based on preoperative imaging and intraoperative findings, eight cats had suspected metastasis at the time of surgery (22.2%). Twenty-eight cats survived to discharge (77.8%). Median progression free interval (PFI) could not be determined, as only six cats developed suspected recurrence (16.7%) and seven cats developed suspected metastasis (19.4%). The all-cause median survival time (MST) was 203 days (95% confidence interval [CI]: 84, 1379 days). When cases that died prior to discharge were excluded, MST increased to 1217 days (95% CI: 127, 1641 days). One-year, two-year, and three-year survival rates were all 40.4%. Neither renal tumour histologic subtype nor the presence of preoperative azotemia, anaemia, erythrocytosis, haematuria, or suspected metastasis at diagnosis were found to influence survival. For cats surviving to discharge, prolonged survival times were possible. Further studies are necessary to elucidate other potential prognostic factors, the utility of postoperative adjuvant treatment, and to identify cats at-risk of mortality in the perioperative period.

Abstract
Case summary A 10-year-old neutered male domestic shorthair cat was diagnosed
with renal adenocarcinoma associated with hypertrophic
osteopathy. The cat was referred for chronic ambulation
difficulties. The physical examination showed a painful
thickening of all four limbs, a right cranial abdominal mass and
a conjunctival hyperaemia. Radiographic findings were consistent
with extensive periosteal new bone formation involving not only
the diaphyses of the fore- and hindlimbs, but also of the
pelvis, tarsus and carpus. Abdominal ultrasonography and CT
revealed a mass within the right kidney and a primary neoplasm
was suspected. A ureteronephrectomy of the right kidney was
performed and histopathology confirmed the diagnosis of renal
adenocarcinoma. Although clinical improvement of the lameness
occurred after surgery, no radiographic changes of hypertrophic
osteopathy lesions were observed at the 9-month follow-up. Relevance and novel information Feline cases of hypertrophic osteopathy are rarely reported in the
literature and only a few of them were associated with abdominal
neoplastic diseases. To our knowledge, this is the first case of
renal adenocarcinoma associated with hypertrophic osteopathy in
a cat.

Abstract
A 3-year-old mixed-breed female cat was diagnosed with a ventricular septal defect of the heart through an echocardiogram. After a 9-month treatment, progressive and diffuse hard thickening of all limbs was observed, which on radiographic examinations, revealed a marked thickening of the long bones. The necropsy findings were limited to the appendicular skeleton and thoracic vertebrae, in addition to a severe cardiac interventricular septal defect and lung edema. The histological evaluation revealed severe replacement of the cortical bone by spongy bone in all bone fragments examined. This is the first report of hypertrophic osteopathy occurring in association with a cardiac malformation in a cat.

Abstract
OBJECTIVE To evaluate through differential diagnosis whether hypertrophic osteoarthropathy was present on an adult macaque skeleton. MATERIALS Skeletal remains of a well-preserved adult macaque (Macaca) of unknown species curated by the archaeology department at University College London. METHODS Macroscopic and radiographic evaluation of pathological lesions. RESULTS Widespread bilateral and symmetrical periosteal new bone growth primarily affecting the limbs was observed. CONCLUSION A careful differential diagnosis of the lesions and comparison with previously published cases of hypertrophic osteoarthropathy among humans and non-humans suggests this animal displays a case of Hypertrophic osteoarthropathy. SIGNIFICANCE Only been three reported cases of HOA in non-human primates have been reported, and all were apes. This study serves as the first reported case of HOA among non-hominoid simians, providing a detailed description of the skeletal lesions to aid future with paleopathological analyses. LIMITATIONS Small sample sizes for comparison and lack of context for this specimen limits discussion of the scope of this disease among non-human primates. SUGGESTIONS FOR FURTHER RESEARCH Re-evaluate skeletal collections which have not been subject to recent osteological and pathological analysis.

Abstract
Case summary An 11-year old neutered female domestic shorthair cat presented for investigation of a large, partially ulcerated skin mass in the area of the left scapula. The cat had been vaccinated 6 weeks previously in the same area. Haematology showed a marked neutrophilia and monocytosis. Tru-cut biopsies were taken and histopathology was consistent with a high-grade soft tissue sarcoma. Thoracic radiographs and abdominal ultrasound revealed no abnormalities. Moderate mixed (palisading, brush border and smooth) periosteal reaction was seen on the diaphysis of long bones at the time of the radiographic examination. Magnetic resonance imaging of the mass showed infiltration within deeper tissues and the owners elected euthanasia. Post-mortem examination confirmed the presence of hypertrophic osteopathy with a concurrent injection-site sarcoma. No evidence of intra-thoracic or intra-abdominal disease was found. Relevance and novel information To our knowledge, this is the first report where hypertrophic osteopathy has been described in a cat with a soft tissue sarcoma, most likely an injection-site sarcoma.

Abstract
A 13-year-old domestic shorthair cat was presented with weight loss and azotemia. Abdominal ultrasound revealed a large cystic space- occupying lesion with multiple septae in the left kidney. A core needle biopsy yielded a renal cystadenoma originating from the epithelial cells. This report describes the clinical, ultrasonographic and computed tomographic features and the growth progression of a renal cystadenoma. We describe the first attempt to apply the human Bosniak classification to a cat with renal cystic neoplasia to differentiate between benign and malignant lesions. Cystadenoma should be a differential diagnosis in cases of renal cystic space-occupying lesions. Other differentials, imaging features to differentiate benign and malignant lesions and the risk of malignant transformation will be discussed.

Abstract
CASE HISTORY A 6-year-old, neutered, female Angora cat presented with a history of lethargy and anorexia for 2 months and a clinically palpable and gradually enlarging, solid mass in the abdominal cavity extending from the last costal arch to the pelvic cavity. CLINICAL FINDINGS Examination of the cat revealed jaundice, dehydration and hypothermia. Haematological manifestations included lymphopenia and substantial decrease in haematocrit value. Biochemical analysis of the blood revealed hypoglycaemia, three-fold elevated blood urea nitrogen values, increased level of serum aspartate aminotransferase and increased total bilirubin while the creatinine level was normal. Ultrasonographic examination of the abdomen showed a disrupted and large hypoechoic area around the left kidney. The cat was anaesthetised and the left kidney was removed, but the cat died following surgery. PATHOLOGICAL FINDINGS On post-mortem examination, the left kidney was markedly enlarged and both the cortical and medullary parenchyma were replaced by confluent, multilobulated, pale tan-white, firm nodular masses protruding above the capsular surface. Metastasis was not observed. Cytological examination revealed a population of spindle-shaped cells of variable size, with abundant coarse chromatin and occasionally prominent nucleoli. Initial sections of the kidney were indicative of undifferentiated sarcoma confirmed by immunohistochemistry revealing vimentin-positive and cytokeratin-negative results in all tumour tissues. Additional sections showed very small amounts of both cytokeratin-positive and vimentin-positive areas. DIAGNOSIS Sarcomatoid renal cell carcinoma (SRCC) with scant epithelial components originating from left kidney. CLINICAL RELEVANCE Clinical and pathological features were similar to those of human SRCC, even though there was no evidence of metastases. Immunohistochemistry for vimentin and cytokeratin may be useful for definitive diagnosis of renal cell carcinoma with sarcomatoid differentiation, although staining of sections from several different parts of the tumour may be necessary. When a primary renal tumour is presented, SRCC should be considered as this diagnosis may influence treatment protocols and the clinical outcome.

Abstract
Os achados clínico-patológicos de sete casos de osteopatia hipertrófica em cães foram estudados. Os cães afetados apresentavam sinais clínicos indicativos de envolvimento ósseo e lesões macroscópicas principalmente nos ossos longos dos membros. As lesões consistiram de neoformação óssea periosteal detectada em exame radiográfico, na inspeção óssea durante a necropsia e, com grande nível de detalhamento, em espécimes ósseos macerados. A proliferação óssea observada era parcialmente circunferencial e ocorreu principalmente na diáfise dos ossos longos. Era constituída por trabéculas ósseas de tamanho e espessura irregulares que estavam dispostas de forma perpendicular ao córtex ósseo original. Em todos os casos as lesões de osteopatia hipertrófica foram associadas a neoplasmas pulmonares (primários ou metastáticos).
