TRIM24 and dermatomyositis: Studies have shown that patients with DM have a significantly higher risk of developing malignant tumors compared to the healthy population, with approximately 15–30% of DM patients suffering from associated malignancies [3], and the pathogenesis of DM with malignant tumors has not been investigated to date, with some studies hypothesizing that it may be related to autoimmune disorders, TIF1 gene mutations and heterozygous deletions, and reduced immune surveillance capacity of the body [4, 5].
