Jejunal perforation complicating dermatomyositis.

INTRODUCTION

Small bowel perforation is rare in dermatomyositis (DM). However, it is associated with high rates of morbidity and mortality. In line with the SCARE criteria, we describe a case of jejunal perforation for a DM patient (Agha et al., 2018 [1]).

CASE PRESENTATION

A 63-year-old woman had been treated for DM with high dose steroid 1 month prior to the onset of severe abdominal pain. Computed tomography (CT) revealed free air in abdominal cavity and fluid around the small bowel. She was diagnosed with small bowel perforation and underwent emergency surgery. Emergent surgery showed perforated jejunum which was resected. Pathologic reports revealed mesenteric small-vessel vasculitis with a perivascular inflammatory cell infiltration.

CONCLUSION

Perforation of the small bowel for DM patients is rare. However, the early diagnosis of bowel perforation is difficult in DM because it can mimic other gastrointestinal manifestations such as ileus, ischemic colitis and peritonitis. To minimize mortality via an early diagnosis and a timely treatment, it is important to examine the patient's clinical history and employ a proper medical imaging modality such as CT even when lab findings are nonspecific and atypical.
