Dermatomiositis clásica. Reporte de un caso

Abstract

Introduction

Dermatomyositis is an inflammatory myopathy of variable course with different clinical manifestations, predominantly in the skin, which can present a chronic, progressive evolution with irreversible muscle damage and significant morbidity and mortality. The objective of this article is to describe the clinical case of a patient with classic dermatomyositis.

Clinical Case Presentation

A 59-year-old woman with a history of high blood pressure experienced muscle weakness in the shoulder and pelvic girdles in October 2022, with significant limitation of her daily activities. Various skin and muscle manifestations were found and motivated the execution of muscle and skin biopsies and electromyography. According to the findings on physical examination and the results of the other studies, the diagnosis of a classic adult dermatomyositis not associated with neoplastic processes was proposed. Treatment with hydroxychloroquine and immunosuppressants was initiated, with an adequate therapeutic response.

Conclusion

The accurate diagnosis of dermatomyositis requires the integration of the clinical picture, laboratory studies, histology and electromyography. This allows for the initiation of appropriate treatment in order to obtain, in most cases, a satisfactory clinical response.
