Abstract

The study was carried out to determine the effect of Borreria verticillata aqueous extract on Adenium obesum stem bark aqueous extract induced histopathological responses in the gill, intestine, liver, and kidney of Clarias gariepinus juveniles. The study consisted of ten (10) groups of fifteen (15) fish each. Groups II - V received 25, 50, 100, and 200 mg/L of the BVAE, respectively. Group VI received 0.838 mg/L of AOAE only (10% of LC50), while groups VII - X received the combinations of the extracts (GII + GVI, GIII + GVI, GIV+GVI, and GV + GVI, respectively). The histopathology observed in Group VI included complete fusion of secondary lamellae and congested blood vessels, hepatic congestion, periportal inflammation, vacuolation, and hyperplasia of bile canaliculi, hypertrophy of the muscular layer and lamina propria and hyperplasia of the goblet cells, congestion of renal blood vessels, tubular degeneration, and swollen glomeruli. The histopathology induced by exposure in GVI in the gills, liver, and kidneys were ameliorated by the administration of Borreria verticillata extract in Clarias gariepinus juveniles in terms of severity which is more in the gill where there is complete club shaped gill in exposed fish compared to the Borreria verticillata extract treated groups.

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.
