Tomato plants - leaves (and some fruit) suddenly curled and discoloured... Help!

Apologies for the possible thread hijack but it's blight related.

A section of a stem of an outdoor tomato has gone brown, looking pretty much like blight.

The only doubt I have is that there's no sign of any problems on the leaves where I thought blight hit first, and I'm not sure the situation has got worse in the last 24 hours.

Before I bin it, any chance it could be anything else? Haven't bothered posting a photo as I'd say visually the stem looks pretty blight like. It's not mushy in any way and still has its structure, but it has the color of death.

Is it rubbing on anything? I have occasionally thought I had something like blight on a tomato stem but realized it is just where string or another branch has rubbed the stem. If it is blight you will find out pretty quickly and by now there is probably not a lot you can do about it.

A similar thing happened to me a few years ago and it turned out to be blight. It got to one of my plant's lower stem halfway through the season ( though too early for ideal blight conditions) it just stayed brown in a restricted area and the rest of the plant stayed healthy for many more weeks until eventually in autumn it started progressing from that area of the stem eventually taking out the whole plant.

Back to the OP I don't whereabouts you are but I haven't closed my green house door for a good few weeks now.

As to that infected/affected tom BM's post #11 if the light brown patch has a papery feel to it I would guess at sunscald, mainly because it is on the side of the tom facing the glass and would therefore be susceptible.
