Card was wordy, and I could not find a description of a TRH-producing tumor in any mainstream resource or even in any research article. Amboss and FA 2023 only list TSH-producing pituitary adenoma (thyrotropic adenoma) as a central cause of hyperthyroidism
UpToDate describes a "TSH-mediated hyperthyroidism" which provides a more succinct wording to capture the meaning of the initial card.

Current version may not be perfect, but suggested change does not have a clear teaching point, removing the utility of the card
