Chronic peripheral edema in a patient with rheumatoid arthritis.

Abstract

Chronic peripheral edema is a very common yet underestimated problem. It is of utmost importance to investigate various possible causes and understand the pathophysiological mechanisms of chronic peripheral edema in order to determine the optimal treatment. This case report presents the case of a polymorbid patient with a deformity-causing type of rheumatoid arthritis and a 1-year history of progressive symmetrical peripheral edema. Based on an extensive diagnostic investigation, the patient was diagnosed with a combined form of chronic peripheral edema comprised of true lymphedema, which was confirmed by lymphoscintigraphy, and filtration edema due to muscular inactivity. Edema as a side effect of tocilizumab was also suspected.
