A diagnosis of paraneoplastic TTP (pTTP) was made as we found a low ADAMTS‐13 activity (< 10%) and the presence of anti‐ADAMTS‐13 IgG antibodies, both being very infrequent or absent in gemcitabine‐induced (G)‐TMA [6, 7, 8, 9, 10, 11, 12]. Here, ADAMTS13 is linked to thrombotic thrombocytopenic purpura.
