Alternative plural of adenoma, using the Greek/Latin plural form rather than the English -s ending.
From Greek adeno- 'gland' + -oma 'tumor', with -ata representing the Greek neuter plural form. Medical and scientific fields often preserve Greek and Latin plurals.
The existence of both 'adenomas' and 'adenomata' shows how English borrows medical language from Greek/Latin—scientists can't quite decide whether to fully anglicize terms or keep them in their original forms, creating vocabulary flexibility!
