INTRODUCTION: Paraneoplastic syndromes are frequent in patients with renal cell carcinoma. Dermatomyositis is an idiopathic inflammatory myopathy that may be associated with neoplasms. This case aims to describe the rare association of dermatomyositis with renal cell carcinoma and to increase clinical suspicion of this neoplasm when systemic rheumatologic symptoms are present.
CASE PRESENTATION: A 35-year-old female developed severe rheumatologic symptoms (progressive muscle weakness, heliotrope rash, and Gottron's papules). Clinical and laboratory findings indicated dermatomyositis. During the investigation, computed tomography revealed a left kidney solid mass. She underwent a left radical nephrectomy, and histology confirmed renal cell carcinoma. After 3 months, dermatomyositis manifestations disappeared and the patient withdrawn steroid therapy.
CONCLUSION: Most paraneoplastic syndromes associated with renal cell carcinoma are only cured with nephrectomy. We highlight the potential role of surgery in dermatomyositis caused by renal cell carcinoma. The recurrence of symptoms related to the syndrome should alert for disease progression.
