Ryan Jeffery [15 October] Please advise Is it a tumour of nasal cavity? Robert Campbell, [16 Oct 2022 at 07:23:22]: Dd list for me would be nasal Cryptococcus, SCC, epithelial tumours of nasal turbinates. But have seen similar in cattle before ended with Aspergillus on culture and histopathology in one and Cryptococcus in another. Hope this is helpful.
