Core Tip
Core tip: Dermatomyositis is associated with an increased risk of gastrointestinal (GI) malignancies based on large-population based studies. These prior studies utilized code-based search strategies and did not perform individual chart review. The yield of endoscopy in this patient population is not known. In this study, endoscopy identified no cases of malignancy and was of low yield, likely similar to the general population, in the identification of pre-malignant findings. Code-based searched strategies were inaccurate in the identification of dermatomyositis, calling into question the results of prior population-based studies. The association between increased GI malignancy and dermatomyositis may be lower than previously reported.
