Relationship between malignancies and autoimmunity. A literature review and analysis of a clinical case

There is a complex bidirectional relationship between rheumatic diseases and cancer. Certain diseases, in particular dermatomyositis, polymyositis, rheumatoid arthritis, systemic lupus erythematosus, Sjogren’s syndrome, sclerosis, on the one hand, are associated with an increased risk of malignant neoplasms against background disease, contributing to cancer due immunological stimulation. On other it can manifest as result autoimmune reactions caused by primary form paraneoplastic syndrome. Paraneoplastic syndrome symptom or set symptoms that secondary process. These from substances secreted tumor (hormones biologically active substances) immune reaction cells (autoimmune reactions, formation complexes, suppression system), involving various organs systems distant focus metastases. This paper presents literature review about greater extent neoplasms, clinical case which manifestation nephritis coincided detection papillary thyroid carcinoma.
