Rosai-Dorfman disease (RDD) is a rare histiocytic disorder characterized by the proliferation of non-Langerhans cells within the lymph nodes, and occasionally in extranodal sites. We report a case of RDD presenting as a left jugal swelling in a 43-year-old male. Imaging studies revealed a poorly defined lesion infiltrating the subcutaneous and muscular planes, as well as the maxillary bone. Biopsy confirmed the diagnosis of RDD. Treatment included surgical excision, followed by low-dose radiation therapy. The patient remained asymptomatic during a one-year follow-up.
