Overlap syndrome is a term used to describe two or more systemic rheumatic diseases identified in the same patient, in which
each disease fulfils its own diagnostic criteria. Inflammatory myopathies such as Dermatomyositis are associated with an increased
risk of malignancy and interstitial lung disease. It may overlap with Systemic Sclerosis, Systemic Lupus Erythematosus, Mixed
Connective Tissue Disease and less often Rheumatoid Arthritis.
