I don't recall the Vit D being mentioned. I didn't see the whole paper, but a quote on a Wiki article.
However here is an article on Google that uses the word photosynthesis in the title (and it is about Vit D).
Here is another point of view...if it were even possible to
make humans photosynthetic:

I don't see how photosynthesis as we apply the term in English would pertain to disease. Photosynthesis is to provide FOOD for the organism, not cure diseases.

But I do see how words that may get changed around from translation from another language might be used in the wrong context.

Then there are articles like this????:

And finally... there is Morgellon's disease. This occurs when some people contract a bacteria thought to live in warm stagnant water, and then they develop lesions on the skin where plant fibers come out! This was initially thought to be a hoax and it was quite controversial on the net for years. One theory was that we all have plant DNA in our "junk" DNA strands with is inbetween our genes. And that this bacterium somehow activated that plant DNA to produce colored fibers which grow out of the skin!

I recall this subject on a news program about 3 yrs or so ago.
Interviews with the scientists and patients, and their doctors.
