Early pulmonary manifestations of dermatomyositis : a case report

الملخص EN

Introduction: Dermatomyositis (DM) is an idiopathic connective tissue disease with a wide range of systemic manifestations.

Progressive proximal skeletal muscle weakness and symmetric and inflammatory infiltrates are the main clinical and histological features of DM.

Case Presentation: In this study, we report the case of a 43-year-old male with DM and early pulmonary manifestations.

A 50 mg/g daily dose of Prednisolone was administered for the case.

The symptoms of muscle weakness improved after 2 weeks.

Commonly, pulmonary diseases occur after the occurrence of other connective tissue diseases.

However, in the present case, pulmonary manifestations were observed many years before the incidence of DM symptoms.

Conclusion: The DM with Pulmonary involvement is associated with worse outcomes; accordingly, a higher rate of mortality is reported among these patients.

Based on the literature, the neutrophil-lymphocyte ratio and platelet-lymphocyte ratio are reliable markers for the diagnosis of DM, along with lung problems.
