Granulomatous pericarditis associated with systemic Mucormycosis in a finless porpoise (Neophocaena phocaenoides).
An adult male finless porpoise (Neophocaena phocaenoides) kept in an aquarium in Japan displayed loss of appetite and reduced body weight over several months. Necropsy examination revealed the presence of lesions in the pericardium, lung, and mediastinal and pancreatico-duodenal lymph nodes. Microscopically, these comprised regions of necrotizing granulomatous inflammation with multinucleated giant cells and surrounding fibrosis. Fungal hyphae were identified within macrophages and the extracellular tissue. Immunohistochemical labelling determined that these organisms were of the order Mucorales. A diagnosis of granulomatous pericarditis associated with systemic mucormycosis was made.
