CASE REPORT: A 60-year-old female @entity1 underwent craniotomy for a @entity75 in the frontoparietal lobe. Histologically, it turned out to be a metastasis from an @entity420 . The @entity5 was found in the upper lobe of the left lung. The @entity1 had whole brain radiation therapy only, the @entity2 was not treated. 4 years later, she presented with @entity1600 . A biopsy showed dilated sinuses filled with histiocytes, but no @entity5 cells. The diagnosis of sinus histiocytosis with massive @entity3329 was made ( @entity9312 ). Without any treatment, the @entity4 resolved completely a few weeks later. Similar episodes were observed several times in the following years. The @entity1 died more than 7 years after the diagnosis of a metastasizing @entity2 due to @entity55 . CONCLUSION: In a @entity1 with a @entity2 and suspected supraclavicular lymph node spread, Rosai-Dorfman's syndrome should be considered as a rare differential diagnosis.
