Abstract

Canine Parvovirus enteritis (CPV-2) is a highly infectious viral disease occurring in puppies resulting in high mortality with a myriad of clinical signs, hematological and biochemical changes during the progression of the disease. This study investigated hematological and biochemical changes in 30 CPV-positive dogs in Ibadan, Nigeria. Severe non-regenerative anemia (35.71%) and leukopenia (22 cases) were prevalent. Thrombocytopenia was severe in 73.33% of cases. Further analysis revealed normocytic hypochromic anemia in 42.86%, microcytic hypochromic anemia in 28.57%, and leukopenia categorized as mild (5), moderate (12), or severe (5). Biochemical changes included hyperproteinemia (26.7%), hyperalbuminemia, hyperglobulinemia, and elevated liver enzymes in some cases. Renal dysfunction was evident in 16.7% of dogs with elevated creatinine. Significant differences (p<0.05) were observed between infected and healthy dogs. These findings underscore the critical impact of CPV on hematological and biochemical profiles, necessitating supportive care and emphasizing the crucial role of vaccination in disease prevention.

Abstract

Canine transmissible venereal tumor (TVT) is a naturally occurring, transmissible neoplasm primarily affecting the genitalia in dogs. Though generally benign, it can rarely metastasize to other body parts. This report describes a rare case of metastatic TVT in a 2-year-old female Boerboel, presenting with a large, ulcerated vulvar mass and metastases to the popliteal lymph node and mammary glands. Clinical findings included progressive mass growth, emaciation, and systemic symptoms. Hematological tests revealed non-regenerative anemia and elevated white blood cell count, while cytological examination identified neoplastic round cells with high nucleus-to-cytoplasm ratios and mitotic figures. The dog was treated with vincristine chemotherapy, metronidazole, vitamin C, and a diet supplemented with crude sap extract of Telfairia occidentalis at 120 mg/kg once daily. Significant tumor regression and clinical improvement were observed after four weeks, although persistent anemia and borderline hypoproteinemia were noted. By the fifth week, the mass had notably reduced, and the dog's condition continued to improve, though some hemorrhage remained. This case highlights the rare occurrence of metastatic TVT and underscores the effectiveness of vincristine in treatment, emphasizing the need for prompt diagnosis and management despite its generally low metastatic rate.

Abstract

Simultaneous occurrence of cutaneous papilloma and vaginal fibroepithelial polyp in old dogs is rare, making such cases clinically and academically significant. An eight-year-old female Boerboel presented with a one-year history of non-pruritic, wart-like skin lesions and a large vulvar mass observed on the day of presentation. Clinical examination, fine-needle aspiration, surgical excision, and histopathological analysis were performed to establish the diagnosis. The vulvar mass measured 16 × 10 × 8 cm, was firm, hyperemic, and smooth, with focal necrosis and hemorrhage. Cutaneous lesions were small, irregular, and cauliflower-like, located on the flank and hind digits. The client had initially misinterpreted the associated bloody vaginal discharge as estrus. Fine-needle aspirates from the vulvar mass showed predominantly cornified epithelial cells. Histopathological examination confirmed the skin lesions as cutaneous papillomas, characterized by hyperplastic stratified squamous epithelium with orthokeratotic hyperkeratosis, and acanthosis. The vaginal mass was diagnosed as a fibroepithelial polyp composed of a hypocellular stroma of bland spindle cells, non-keratinized squamous epithelium, and dense neutrophilic infiltration with necrotic debris. This case adds to the sparse body of knowledge on concurrent cutaneous and reproductive tract lesions in dogs. It emphasizes the critical role of thorough clinical evaluation and histopathological confirmation in distinguishing lesions that may appear related but are distinct. Early surgical intervention is essential for effective management and a favorable prognosis, and systematic documentation of such cases enhances understanding of unusual presentations in veterinary practice.

Abstract

Pathologic mineralization refers to the abnormal deposition of calcium salts in tissues. In dogs, metastatic calcification is an uncommon but serious complication of chronic kidney disease (CKD), resulting from disturbances in calcium/phosphorus metabolism or renal damage by infectious agents. A 5-year-old female Boerboel was presented because of one week of anorexia. Clinical assessment revealed severe emaciation, dehydration, azotemia, hyperphosphatemia, and concurrent ehrlichiosis. Despite oxytetracycline and doxycycline therapy for two days, the dog died. Necropsy and histopathological examination were performed. Grossly, there was extensive mineralization of the diaphragm, intercostal muscles, pleura, pharynx, and great vessels. Histopathology showed tubular epithelial degeneration, protein casts, tubular ectasia, and interstitial fibrosis, consistent with advanced CKD. Laboratory findings of azotemia, hyperphosphatemia, hypoalbuminemia, and hypercalcemia supported renal failure as the underlying process driving the soft tissue mineralization.  Extra-renal lesions included hepatocellular atrophy with vacuolar change, Kupffer cell hyperplasia, bronchointerstitial pneumonia with pulmonary edema, and hemorrhagic follicular cystitis with mononuclear infiltration. The combined gross and histopathological findings demonstrate how renal failure-induced mineral imbalance can drive widespread soft tissue mineralization. Veterinary clinicians must monitor calcium/phosphorus status to anticipate life-threatening sequelae.
