RESUMO
Two unrelated coatimundi (Nasua nasua) had bilaterally enlarged adrenal glands at necropsy, and sections of the glands from both animals had histopathological features consistent with neoplasia. They were differentiated from an adrenal cortical tumour on the basis of their light microscopical morphology, immunoperoxidase staining and electron microscopic studies and a final diagnosis of phaeochromocytoma was made. To the authors' knowledge, these are the first reported cases of phaeochromocytoma in coatimundi.

A captive adult male Eastern barred bandicoot (Perameles gunnii) presented with three palpable subcutaneous masses in November 1998. A diagnosis of haemangiosarcoma was made based on histological examination of one excised mass. Euthanasia of the animal was performed 11 days postsurgery and a proliferative lesion in the paralumbar musculature and similar, smaller proliferative lesions surrounding the right popliteal lymph node and in the ventricular wall of the heart were found. Metastatic lesions were found in the liver and lung. The histological features of the neoplastic tissues supported the diagnosis of a poorly differentiated, disseminated haemangiosarcoma. This is the first reported case of haemangiosarcoma in the Eastern barred bandicoot.
