Abstract

Idiopathic inflammatory myopathy (IIM) is known for its association with malignant diseases. Moreover, various solid organ malignancies, such as ovarian, breast, lung, esophageal, stomach, and colorectal cancers, have been reported to occur with IIM. Furthermore, its relationship with hematologic malignancies, including non-Hodgkin lymphoma, myeloma, and leukemia, has been reported. However, to date, IIM related to pancreatic cancer has scarcely been reported, particularly in patients with polymyositis (PM). Therefore, here we report a case of PM developed immediately after the diagnosis of pancreatic ductal adenocarcinoma.
