Rosai Dorfman disease (RDD) is a rare disorder that typically presents with bilateral cervical lymphadenopathy and follows a benign course.Objective:
We present a case of late-onset atypical primary cutaneous RDD that is resistant to treatment modalities described in the literature.Methods:
An 84-year-old woman presented with a 7-year history of cutaneous lesions histologically consistent with RDD. She later failed initial treatments of acitretin and thalidomide.Conclusion:
Physicians must be aware of unusual presentations of RDD. Also, further treatment options must be explored for patients resistant to classical management of RDD.
