Dear Dr Addison, I don't know whether it was on the mailbase but I presented a poster at last years FOCUS on a case of pseudoanaphylaxis after eating tuna fish - which turned out to be due to scombroid poisoning, rather than a true allergic reaction. If this was the case you were thinking of I'd be happy to send you further details. Louise Moran -----Original Message----- From: Dr G. M.

I seem to recollect a case on the list about a patient who had an unusual reaction to eating fish (? tuna). I have failed to locate the case searching the archive and I wonder if others with a greater memory span than mine can point me in the right direction.
