Use of Mohs Micrographically Controlled Surgery in the Management of Equine Penile Squamous Cell Carcinoma     

Paul G. Hazen  Brett Berthold  Karen L. Turgeon  Gerard Nuovo 《Journal of Equine Veterinary Science》2009

A 30-year-old palomino Standardbred horse was seen with a persistent penile squamous cell carcinoma. After failure using multiple treatments, surgical removal was successfully carried out under local anesthesia using Mohs micrographically controlled surgery. Subsequent examination of the malignant tissue identified bovine papillomavirus exclusively within the nuclei and cytoplasm of tumor cells. The use of Mohs surgery would appear to be useful as an effective, precisely controlled treatment for managing genital squamous cell carcinoma in equine subjects. The presence of papillomavirus within tumor cells would suggest the possibility of causation by an oncogenic papilloma virus and would indicate that careful monitoring of the surgical site should be performed.  相似文献   

Endoscopic-Assisted Intracranial Tumor Removal in Dogs and Cats: Long-Term Outcome of 39 Cases     

L.S. Klopp  S. Rao 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》2009,23(1):108-115

Background: The benefits of endoscopic assistance to remove intracranial tumors in small animals are not described.
Objective: To evaluate the effectiveness of endoscopic-assisted intracranial tumor removal in dogs and cats.
Animals: Thirty-three dogs and 6 cats with intracranial tumors.
Methods: Retrospective study. CBC, serum chemistry profile, coagulation testing, blood typing, and systemic tumor staging, which included 3-view thoracic radiographs and abdominal ultrasound examination, were performed to detect other significant underlying disease in preparation of the animal for surgery. Magnetic resonance imaging was used in 37/39 cases to image the brain tumor. Surgical approach was dictated by the location of the tumor. Histopathologic examination of the tumor tissue was performed in all cases. Animals were followed throughout their postoperative course for complications and survival times. Statistical analysis (Kaplan-Meier curves) was performed to obtain median survival times in dogs with meningiomas.
Results: Use of an endoscope resulted in visualization of residual tumor and potentially more complete removal of the brain tumors. There were no clinically important complications associated with the use of the endoscope. Median survival time was 2,104 days for dogs with forebrain meningiomas surgically removed with endoscopic assistance and 702 days for dogs with caudal brain meningiomas.
Conclusions and Clinical Importance: These results demonstrate that the use of an endoscope to assist in brain tumor removal is apparently safe and might result in improved survival times.  相似文献   

CONTRAST-ENHANCED COMPUTED TOMOGRAPHY AS A PREOPERATIVE INDICATOR OF VASCULAR INVASION FROM ADRENAL MASSES IN DOGS     

RYAN M. SCHULTZ  ERIK R. WISNER  ERIC G. JOHNSON  JENNIFER S. MACLEOD 《Veterinary radiology & ultrasound》2009,50(6):625-629

The purpose of this study was to determine if contrast-enhanced computed tomography (CT) accurately reflected vascular luminal invasion by adrenal masses in dogs. Medical records of 15 dogs with 17 adrenal masses that underwent preoperative CT imaging were reviewed. Presence or absence of vascular invasion was confirmed by surgery or necropsy/histology. Vascular invasion was identified correctly using contrast-enhanced CT in 11/12 dogs. The sensitivity and specificity of contrast-enhanced CT for vascular invasion compared with surgery or necropsy was 92% and 100%, respectively. The positive predictive value and negative predictive value of contrast-enhanced CT was 100% and 90%, respectively. The accuracy was 95%. In one dog, invasion of the phrenicoabdominal vein was not identified on CT images. Six of eight masses with vascular invasion where a histologic diagnosis was obtained were malignant. Four of four pheochromocytomas invaded adjacent vasculature. Contrast-enhanced CT provided accurate preoperative assessment of adrenal masses. Vascular invasion by adrenal masses in this study occurred by way of the lumen of the phrenicoabdominal vein with subsequent intraluminal extension into other veins, rather than by erosion through vessel walls.  相似文献   

Lack of Modifying Effects of Intratracheal Instillation of Quartz or Dextran Sulfate Sodium (DSS) in Drinking Water on Lung Tumor Development Initiated with 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) in Female A/J Mice     

Yokohira M  Hashimoto N  Yamakawa K  Suzuki S  Saoo K  Kuno T  Imaida K 《Journal of toxicologic pathology》2009,22(3):179-185

The purpose of the present study was to investigate the effects of inflammation, induced by intratracheal instillation (i.t.) of quartz as an environmental factor in the lung or drinking of dextran sulfate sodium (DSS) as an environmental factor in the colon on lung tumors in female A/J mice initiated with NNK. For comparison, colonic preneoplastic lesions, aberrant crypt foci (ACF), were also assessed. A/J mice at 6 weeks of age were divided into 5 groups, and Groups 1, 2 and 3 were pretreated with NNK (2 mg / 0.1 ml saline / mouse, intraperitoneal injection) at week 0. For a week, 2% DSS in drinking water was administered to the mice in Groups 2 and 4 beginning in week 1. In week 2, the mice of Groups 3 and 5 were exposed to intratracheal instillation of quartz (0.1 mg/rat) suspended in 25 μl saline. The experiment was terminated after 16 weeks. The results for the lung tumors and colonic ACFs showed a lack of modifying effects of the inflammation in either site. Hematologically and histopathologically, the inflammation induced by 0.1 mg quartz in the lung and 2% DSS in the colon was lacking or only mild at the end of 16 weeks. These results suggest that there may be differences in sensitivity to inflammation that determine tumor promoting potential.  相似文献   

Rapid visualization of mammary gland tumor lesions of dogs using the enzyme-activated fluorogenic probe; γ-glutamyl hydroxymethyl rhodamine green     

Yui HIROSE  Mona UCHIDA  Masaya TSUBOI  Takayuki NAKAGAWA  Leo YAGA  Shingo MAEDA  Yasuyuki MOMOI  Yugo KURIKI  Mako KAMIYA  Yasuteru URANO  Tomohiro YONEZAWA 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2022,84(4):593

Since gamma-glutamyl transpeptidase (GGT) is highly and locally expressed in human breast cancer, a GGT-enzymatically activatable fluorescent probe, gamma-glutamyl hydroxymethyl rhodamine green (gGlu-HMRG), has been developed to detect the human breast cancer area with high performance. In this study, GGT expression and the efficacy of gGlu-HMRG on visualization were investigated in canine mammary gland tumors (MGT). Seventeen non-fixed fresh-frozen MGT specimens and each peritumoral control tissue were utilized. The GGT mRNA levels were highly observed in the tumor specimens compared with the control. GGT immunostaining was mostly observed on the cell membrane and cytosol of the alveolar and duct mammary epithelium of MGT tissues. These signals were strongly positive in several cases while they were mild to not observed in other cases. When gGlu-HMRG solution was dropped to the non-fixed tissue pieces of MGT or control tissues, the fluorescence intensities (FIs) were measured using Maestro in-vivo imaging device. FIs in MGT tissues were significantly higher than each control tissue 20 min after treatment. Based on Youden index method said that the maximum sensitivity and specificity of FI was 82.4% and 82.4%. These findings suggest that GGT is highly expressed in several MGTs in dogs and gGlu-HMRG could visualize at least a part of MGT tissues in dogs. Nevertheless, it should be needed to assess the false-negative areas more carefully in canine than human cases.  相似文献

BackgroundCompression of epidural adipose tissue (EAT) within the scope of cauda equina syndrome (CES) could lead to an enhanced expression of inflammatory mediators, possibly contributing to pain amplification in dogs.ObjectivesTo analyze expression of inflammatory adipo(‐cyto)kines within the EAT of dogs with CES.AnimalsClient‐owned dogs: 15 dogs with CES and 9 dogs euthanized for unrelated medical reasons (controls).MethodsProspective, experimental study. Epidural adipose tissue and subcutaneous adipose tissue were collected during dorsal laminectomy and used for real‐time quantitative polymerase chain reaction. Tissue explants were cultured for measurements of inflammation‐induced release of cytokines.ResultsResults show a CES‐associated upregulation of the cytokines tumor necrosis factor alpha (TNFα: mean ± SD: 18.88 ± 11.87, 95% CI: 10.90‐26.86 vs 9.66 ± 5.22, 95% CI: 5.29‐14.02, *: P = .04) and interleukin‐ (IL‐) 10 (20.1 ± 9.15, 95% CI: 14.82‐25.39 vs 11.52 ± 6.82, 95% CI: 5.82‐17.22, *: P = .03), whereas the expression of the adipokine leptin was attenuated in EAT of dogs with CES (3.07 ± 2.29, 95% CI: 1.80‐3.34 vs 9.83 ± 8.42, 95% CI: 3.36‐16.30, **: P = .007). Inflammatory stimulation of EAT explant cultures resulted in an enhanced release of IL‐6 (LPS: 5491.55 ± 4438, 95% CI: 833.7‐10 149; HMGB1: 1001.78 ± 522.2, 95% CI: 518.8‐1485; PBS: 310.9 ± 98.57, 95% CI: 228.5‐393.3, ***: P < .001).Conclusion and Clinical ImportanceExpression profile of inflammatory adipo(‐cyto)kines by EAT is influenced from compressive forces acting in dogs with CES and might contribute to amplification of pain.  相似文献

Pot-bellied Vietnamese pig with visceral mast cell tumors and mastocytemia     

Abby M. Willey  Brittany S. Baughman  Jennifer M. Beam  Nataly Mamaliger  Gretchen P. Grissett  Amelia R. Woolums  Marjorie J. Williams  Matthew L. Williams 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》2023,52(1):108-111

An approximately 12-year-old female Vietnamese Pot-Bellied Pig was presented to the Mississippi State College of Veterinary Medicine Food Animal Service for anorexia of 2 days duration. On physical examination, the patient appeared depressed and lethargic with significantly pale mucus membranes, open mouth breathing, and nostril flaring. On abdominal palpation, the abdomen was tense and uncomfortable. A complete blood count (CBC) and chemistry profile were performed. The CBC revealed significant anemia and mild leukocytosis characterized by mild neutrophilia with a left shift. Mast cells were rarely observed. Hematocrit = 8.1% (RI 22-50), RBC = 1.25 × 10⁶/μL (RI 3.6-7.8), WBC = 19.85 × 10³/μL (RI 5.2-17.9), Neutrophils = 15.08 × 10³/μL (RI 0-11.4), and Bands = 0.993 × 10³/μL (RI 0-0.019). The chemistry profile was unremarkable with a mildly elevated BUN and slightly decreased total protein and albumin (BUN = 39 mg/dL [RI 4.2-15.1], total protein = 6.2 g/dL [RI 6.6-8.9], and albumin = 2.5 g/dL [RI 3.6-5.0]). An abdominal ultrasound revealed numerous hypoechoic nodules diffusely scattered throughout the hepatic parenchyma. An FNA of one of the hepatic nodules was performed. A mild suppurative component and numerous variably granulated mast cells were observed. A presumptive cytologic diagnosis of mast cell tumor was made. Histopathology was performed, confirming the cytologic interpretation.  相似文献
