Rosai-Dorfman disease (RDD) is a reactive multisystem histiocytosis that typically presents with cervical lymphadenopathy and systemic symptoms. Cutaneous involvement occurs in approximately 10% of cases, and 3% of cases are limited to the skin without nodal or other extranodal involvement. Langerhans cell histiocytosis (LCH) is a clonal histiocytosis with a wide spectrum of presentations ranging from isolated skin or bone disease to multisystem involvement. Rare case reports have identified concomitant presentation of RDD and LCH; however, most of these reports have involved LCH and RDD occurring concurrently but at separate sites. We present a rare case of concurrent RDD and LCH presenting within a single skin nodule. The patient did not have any evidence of systemic involvement and has remained stable without additional treatment. We also review the literature on this unusual co-presentation and suggest possible underlying mechanisms. Finally, we recommend baseline laboratory and imaging studies and discuss treatment options based on the available evidence.
