Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a rare and benign proliferative disease that affects histiocytes. Its etiology remains unclear. Rosai-Dorfman disease primarily affects lymph nodes with many extranodal manifestations present, including cutaneous, pulmonary, ophthalmic, and gastrointestinal. Diagnosis is mainly histologic with the presence of Rosai-Dorfman cells, which demonstrate emperipolesis. We report a case of a 30-year-old man who presented with a facial cutaneous mass and was diagnosed with RDD; he underwent surgical excision. The patient experienced recurrent lesions on the surgical scar and parotid gland as well as the lower back. Treatment consisted of systemic steroids and surgical excision.
