A case of dermatomyositis and ulcerative colitis

Abstract

Introduction: The incidence of idiopathic inflammatory myopathy ranges from 4 to 15 cases per million inhabitants while its prevalence is 60 cases per million inhabitants. Given the identification of clinical forms, it is possible that these figures will increase in the coming years. Incidence and prevalence of ulcerative colitis have been increasing, and it now affects 2% of the world population. Symptoms are determined by the extent and severity of lesions. It is chronic with recurring outbreaks, and there is no medical cure. Dermatomyositis in association with ulcerative colitis occurs extremely infrequently. Objective: This study presents the case of a patient diagnosed with dermatomyositis associated with ulcerative colitis. Clinical Case: The patient was a 70 years white woman, a housewife with no family or epidemiological history of interest. She reported that she had had diarrhea accompanied by abdominal pain, mucus and pus when she was fifty years old. About one year prior to diagnosis, she developed muscle weakness in her shoulders that made it difficult for her to lift her arms. Laboratory, imaging and histopathological tests showed dermatomyositis associated with ulcerative colitis. We point out clinical characteristics, diagnostic means and the therapy used to treat our patient. Conclusions: This case of a patient with clinical manifestations of the very infrequent combination of dermatomyositis and ulcerative colitis should be taken into account by doctors who care for these patients because both conditions have immunological bases and can be expressed in various ways.
