Lung adenocarcinoma and anti-transcriptional intermediary factor 1-gamma positive dermatomyositis complicated with spontaneous oesophageal rupture.

Abstract

A 58-year-old man presented with a two-month history of facial erythema and dry cough. Physical examination revealed typical cutaneous manifestations of dermatomyositis (DM), including heliotrope rash and shawl sign. A chest X-ray revealed a 4-cm mass in the right middle lung. After bronchoscopy and investigation of auto-antibodies, he was diagnosed with co-occurring transcriptional intermediary factor 1-gamma (TIF1-γ) positive DM and lung adenocarcinoma. He was administered oral prednisolone for subsequent muscle weakness, but developed TIF1-γ positive DM-associated oropharyngeal dysphagia complicated by spontaneous oesophageal rupture and died from progression of chemoresistant lung cancer.
