Abstract

|
Rosai-Dorfman disease involves an abnormal proliferation of histiocytes. This abnormal growth tends to occur within the lymph nodes, with occasional extranodal presentation. Rosai-Dorfman disease is a rare disease, and the extranodal cases are even more uncommon. We report a rare case of extranodal Rosai-Dorfman disease in multiple sites in a 56-year-old male patient. Abdominopelvic CT revealed soft tissue attenuation masses, encasing both the renal pelvis and both ureters, as well as the thoracic vertebra. Following the neck sonography, both submandibular glands had an enlarged honey combed appearance. Although Rosai-Dorfman disease is rare, it should be considered as a potential differential diagnosis when multiple sites involving soft tissue attenuation masses are observed with sonogram and CT.
