This case report describes a unique presentation of dermatomyositis-associated pneumonitis. A 44-year-old man presented with repeated episodes of fever, dyspnea, and hemoptysis accompanied with pulmonary infiltrates, on chest CT scan. Hypersensitivity pneumonitis was suspected. Further work-up showed clinical and serologic evidence of dermatomyositis-associated pneumonitis. The patient was treated with oral prednisone and azathioprine. The subject of dermatomyositis-associated pneumonitis is discussed.

Article Synopsis
- Clinical amyopathic dermatomyositis is a skin condition that lacks muscle symptoms and is often associated with anti-melanoma differentiation-associated gene 5 antibodies, particularly in Japanese patients, leading to poor outcomes in those with lung complications.
- A 52-year-old male presented with severe respiratory issues and skin rashes, diagnosed with dermatomyositis-related interstitial pneumonia, but treatment with steroids and immunosuppressants was largely ineffective.
- Despite some initial improvement after switching medications, the patient ultimately faced worsening respiratory failure due to invasive pulmonary aspergillosis, resulting in a fatal outcome.

Objectives: Hemoperfusion (HP) is used to treat various diseases, including sepsis and acute respiratory distress syndrome. However, few studies have explored the efficiency of HP in dermatomyositis-associated acute exacerbation of interstitial lung disease.
Methods: We conducted a retrospective study.

Introduction And Importance: Dermatomyositis (DM) is an autoimmune myopathy primarily affecting both muscles and skin. When muscle weakness is not clinically apparent, but characteristic skin lesions are present, the condition is referred to as clinically amyopathic dermatomyositis (CADM).
Case Presentation: The authors present the case of a 52-year-old female with a typical DM rash, interstitial pneumonia, and multiple skin ulcers.

Background: This study retrospectively analyzed the laboratory data and chest images of patients with amyopathic dermatomyositis associated with interstitial lung disease (ADM-ILD) and patients with other connective tissue disease-related ILDs (CTD-ILDs) to find a characteristic index for the early recognition of ADM-ILD and help clinicians consider the possibility of ADM-ILD as soon as possible.
Methods: In our cohort study, the records of 128 Chinese patients with CTD-ILD, including 33 ADM-ILD patients, 37 rheumatoid arthritis (RA)-ILD patients, 33 primary Sjogren's syndrome (pSS)-ILD patients, 14 systemic sclerosis (SSc)-ILD patients and 11 systemic lupus erythematosus (SLE)-ILD patients. The patients' clinical features, laboratory parameters, and chest HRCT findings were analyzed.
