Rosai Dorfman Disease: A Rare Disease Case Report

Rosai Dorfman Disease (RDD) is a rare benign condition. It was first described by Rosai and Dorfman in the 1960s. The etiology, pathogenesis and true frequency of the disease remain unknown. The disease is characterized by the proliferation of histiocytes in the lymph nodes. Clinically, this enlargement of the lymph nodes must be distinguished from other infectious or malignant causes. Although it is often observed at early ages, in this study, a case of RDD detected in a 66-year-old male patient who came to the hematology outpatient clinic due to axillary swelling was presented. The patient is still being monitored without any symptoms,without treatment.
