Another new organ! is this a golden age of discovery in anatomy?

Twice in fifteen months the popular press has published reports of the discovery of a new human organ. The claims that the mesentery and interstitium are organs come from medical practitioners, not from anatomical scientists. Although both of these anatomical entities are important in the functioning of the body, neither satisfies the requirements that an organ be composed of two or more tissues and perform a special function. Also missing in the recent claim that the interstitium, that is, connective tissues with fluid-filled spaces, is an organ, is a statement to that effect in the original research report. Alas, it appears to be much ado about nothing. Clin. Anat. 31:648–649, 2018.
