Rosai–Dorfman disease (RDD) is a rare histiocytic disorder, which occurs at any age, can affect almost any organs and tissues, does not have pathognomonic symptoms and could be confirmed only by histological examination of the affected tissue. The article describes the successful treatment of a child with RDD with lymph nodes, nasopharynx, subcutaneous tissue, spleen and bones involvement, by multistep surgical treatment and chemotherapy. A review of the literature is provided, including recommendations for the examination and treatment of patients with RDD. The patient's parents agreed to use the information, including the child's photo, in scientific research and publications.
