title: Gastrointestinal basidiobolomycosis in a dog.
abstract: An 8-year-old, spayed, female Shiba dog was presented to a referring veterinarian with a complaint of chronic diarrhea and anorexia. Ultrasound and radiographs revealed an irregular mass in the pelvic cavity. The mass and the affected section of colon were surgically removed. Histopathological examination revealed multifocal coalescing granulomas and effaced intestinal structures. Central necrotic debris surrounded by multinucleated giant cells, lymphocytes, plasma cells and neutrophils was observed. Numerous, irregularly branched hyphae with pale basophilic, thin walls and occasional bulbous enlargements at the tips were present. Polymerase chain reaction identified Basidiobolus ranarum, successfully confirming a definitive diagnosis of basidiobolomycosis. To the best of our knowledge, this is the first report of intestinal basidiobolomycosis in a dog.
