The Authors describe an extremely rare fatal case (sixth case in the literature) of anaphylactic shock following a fluorescein angiography. This is the first report in which the diagnosis of anaphylactic reaction to the dye was made through laboratory analyses. ⋯ Mast-cell tryptase was dosed in serum and a pulmonary immunohistochemical evaluation was performed. Tryptase, a neutral protease of human mast-cells is a potentially important indicator of mast-cell involvement in anaphylactic events.
