In addition, it is worth noting that both DM and PM, especially anti-transcriptional intermediary factor 1-gamma antibody-positive dermatomyositis, are strongly associated with malignant diseases, such as ovarian, lung, pancreatic, enteron, and non-Hodgkin lymphoma, and the highest risk of these malignancies often occurs at the time of DM/PM diagnosis (36, 37). This evidence concerns the gene TRIM33 and dermatomyositis.
