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.

Abstract

Oxidative stress plays a critical role in the pathogenesis of respiratory diseases in small ruminants; however, a comprehensive assessment comparing systemic and local pulmonary oxidative status in naturally infected Nigerian indigenous sheep is lacking. This study evaluated oxidative parameters in serum and bronchoalveolar lavage fluid (BALF) from 210 sheep, including healthy controls and animals with naturally occurring pneumonia. Samples were analyzed for total protein, enzymatic antioxidants (glutathione peroxidase, glutathione transferase, superoxide dismutase), non-enzymatic antioxidants (reduced glutathione, vitamin C), and oxidative stress markers (myeloperoxidase, malondialdehyde, hydrogen peroxide, and nitric oxide). In pneumonic sheep, serum and BALF levels of glutathione peroxide, glutathione transferase, and superoxide dismutase were significantly reduced, whereas levels of myeloperoxidase, hydrogen peroxide, and nitric oxide were markedly increased. Malondialdehyde showed mild elevation. The most significant oxidative disturbances were observed in bronchopneumonia, bronchointerstitial pneumonia, and granulomatous pneumonia. These results demonstrate a pronounced oxidative imbalance in both the systemic and pulmonary compartments of sheep with pneumonia. Therefore, this study provides novel evidence supporting the integration of antioxidant therapy and targeted nutritional management into standard care protocols to mitigate oxidative damage and improve outcomes in pneumonic sheep.
