Abstract.A retrospective study was conducted from 1,919 necropsies of dogs, and 52 cases were selected on the basis of primary or metastatic neoplasia in the pericardium, the heart base, or the myocardium. Primary intrapericardial neoplasms were more frequent than intrapericardial metastases. Hemangiosarcomas were the most frequent primary neoplasms, followed by chemodectomas. Lymphomas were the most frequent metastatic neoplasms, followed by fibrosarcomas and rhabdomyosarcomas. Other neoplasms, either primary or metastatic, occurred rarely.Neoplasms affecting the pericardium, the heart base or the myocardium are infrequent in the dog, representing only a small proportion of necropsy cases. 6,27 Hemangiosarcomas 4,13,27 and chemodectomas 2,4,27,28 are the most frequently observed. Other mesenchymal and epithelial tumors have been sporadically reported. 1,4,7,8,11,12,14,15,17,18,20,23,[25][26][27] Ratios of primary intrapericardial versus metastatic neoplasms and of metastatic mesenchymatous versus epithelial neoplasms are unknown.A 6-year retrospective study was done to determine the incidence of primary or metastatic intrapericardial neoplasia in the dog. The relative frequency of primary versus metastatic and metastatic mesenchymatous versus epithelial neoplasms affecting the pericardium, the heart base, and the pericardium were also investigated. Materials and methodsSelection of cases. Necropsies were performed on 1,919 dogs over a 6-yr period (January 1990 to December 1995 at the Faculty of Veterinary Medicine, University of Montreal. Neoplasms were diagnosed in 184 cases, and 52 of these were selected for study based on their intrapericardial localization.Light microscopy. Tissues were fixed in buffered 10% formalin, embedded in paraffin, sectioned at 5 m, and stained with hematoxylin, phloxin, and saffron (HPS). Giemsa, periodic acid-Schiff, phosphotungstic acid-hematoxylin, Gridley's reticulin and/or Grimelius stains were used on selected sections.Immunoperoxidase. Monoclonal antibodies a were used to detect the presence of desmin, vimentin, alpha-smooth muscle actin (SMA), myoglobin, and cytokeratin and polyclonal antibodies were used for calcitonin, thyroglobulin, muramidase, alpha-1 antitrypsin, kappa-lambda light chains, a and factor VIII-related antigen b on selected neoplasms to confirm the diagnosis. Sections were cut at 5 m and mounted on Received for publication May 14, 1997.slides precoated with poly-D-lysine. Sections were stained by the avidin-biotin complex method using standard reagents. c Sections were deparaffinized in successive xylene immersions, dehydrated through graded ethanols, and rehydrated in distilled water. Endogenous peroxidase activity was blocked with 3% hydrogen peroxide diluted in methanol. Sections were incubated overnight at 4 C with appropriate primary antibody in a humidified chamber, followed by incubation at room temperature in a humidified chamber with appropriate biotinylated antibodies. Sections were then covered with freshly prepared avidin-biotin-peroxidase solu...

“…The frequency of hemangiosarcomas is almost 10 times that of chemodectomas [5]. Less common heart tumors include granular cell tumors [6], chondrosarcomas [7], osteosarcomas [8], fibromas [9], fibrosarcomas [10,11], cardiac lipomas [12], malignant mesenchymal tumors [13], lymphomas [14,15], rhabdomyosarcomas [16,17], neurofibromas [18], angiolipomas [19], myxomas [20][21][22][23], right atrial myxosarcomas [21,24,25], ectopic thyroid carcinomas [26][27][28], and pericardial mesothelioma ( Figure 18-1) [1,5].…”

A 10-year-old female crossbred dog of 6 kg bodyweight was presented with signs of marked abdominal distention. The abdominal skin vasculature appeared prominent. After an exhaustive physical examination, laboratory analysis (table 1) and imaging studies, the case was diagnosticated as Budd-Chiari like syndrome due to lung adenocarcinoma. Abdominal ultrasonography revealed a neoplasia of 4 cm in diameter with irregular borders located in right accessory lung in contact with the caudal vena cava and surface thorax of the diaphragm. Immediately after sonographic diagnosis, the canine was admitted to intensive care and hemodynamically stabilized and submitted to surgery after 24 hrs. Then we made a exploratory thoracotomy with intention of achieve a lung lobectomy. After surgery chemotherapy with doxorrubicin 30 mg/m2 was administered. The objective of our study was to describe the image and pathological data findings in a dog with Budd-Chiari like syndrome; including sonographic findings, treatment and its response, in a syndrome that rarely affect small animals. Although no data are available on incidence of this disease in veterinary medicine, there is no doubt that this is a very serious illness despite its rare appearance. To our knowledge, this is one of the few cases where BCLS is reported associated to lung adenocarcinoma in veterinary medicine.
