摘要: Rosai-Dorfman disease (RDD) is a rare and benign histiocytic proliferative disorder of unknown etiology. It can affect all age groups, particularly young adults. The typical clinical manifestation painless, bilateral, massive cervical lymphadenopathy with or without extra nodal involvement, along fever, weight loss, night sweats. However, thyroid involvement very uncommon. ultrasonographic manifestations RDD are rarely reported. A case involving the that was recorded in our hospital PACS system during 2002–2010 reported here, which initially misdiagnosed as non-Hodgkin’s lymphoma (NHL). In case, ultrasonography revealed diffuse enlargement whole glands heterogeneous hypoechogenicity. Areas linear hyperechogenicity were noted on sonograms multiple enlarged nodes over cervical, supraclavicular, submandibular areas. Though not specific, order to avoid unnecessary surgery total thyroidectomy, ultrasonography-guided core needle biopsy should be performed establish an accurate diagnosis.
