Rosai-Dorfman disease or sinus histiocytosis with massive lymphadenopathy is a benign lympho-histiocytic proliferative disorder initially described with bilateral painless lymphadenopathy (90 %), fever, leukocytosis, elevated ESR, anemia, and polyclonal hypergammaglobulinemia (90 %). Extranodal forms occur in 43% of cases, the skin being the most common site. Around 10% of patients have skin lesions and in 3%, the disease is limited exclusively to the skin. Here, we report a male patient who presented with pure cutaneous lesions which mimic eruptive xanthoma clinically. However, the diagnosis was established histo pathologically. So, high level of clinical suspension is critical to avoid missing such cases.
