Abstract

A 55-year-old man while being evaluated for unexplained weight loss was found to have multiple metabolically active lymph nodes on positron emission tomography-computed tomography (PET-CT) scan, and biopsy from right axillary lymph node demonstrated multiple histiocytes with emperipolesis with S100 positivity, consistent with Rosai-Dorfman disease.
