I wonder what might this disorder be?

Apple    Nepal

I suspect it is a physiological disorder: browning, manifestation of disease, defies usual pattern-less form, in this case being concentric browning of pith. The fruit did not show any external symptoms although the the cutting lead to strikingly foul odor.

If it is indeed physiological then I would suspect that it would be found in all apples on the same branch. Can you investigate and tell us if that is true?

Also, how are apples further away? Do you have other apple trees? What are they like? Can you provide some pictures of the leaves so we might check for foliar diseases like fire blight (a bacterium) that may also infect fruit.

Also, tell us more about your set up (how many trees, what inputs, recent weather)
