Rosai-Dorfman disease (RDD), previously known as sinus histiocytosis with massive lymphadenopathy, is a benign, idiopathic histiocytic proliferative disorder. It commonly affects lymph nodes, but any organ of the body may be involved. Histological findings include characteristic large, pale, histiocytic cells (Rosai-Dorfman cells) exhibiting cytophagocytosis. Immunohistochemically, these histiocytes are positive for S-100 protein and CD68, but stain negatively for CD1a. On electron microscopy, Birbeck granules are absent. RDD limited to the skin is rare, less than 30 cases having been reported to date. We present five further cases of purely cutaneous RDD. Three presented as solitary nodules and one as a large, well-circumscribed plaque. The fifth patient, who was HIV positive, had a rosacea-like facial eruption.

A case of cutaneous Rosai-Dorfman disease (CRDD) presenting as a granulomatous rosacea-like rashs was reported. A 45-year-old Chinese woman presented with a 1-month history of a widespread nonpruiginous papulonodular eruption. The rash had begun on her face and rapidly progressed to involve the neck and extremities. She was otherwise healthy, with no history of fever, malaise, or weight loss. Physical examination revealed multiple symmetrically distributed discrete and coalescing red plaques, papules and nodules scattered over the face, neck and extremities. No appreciable lymphadenopathy or hepatosplenomegaly was noted. There was no mucosal involvement. The biopsy specimen obtained from the face demonstrated the epidermis was normal, while the superficial dermis contained sheets of histiocytes with abundant, focally foamy cytoplasm. The histiocytes were surrounded by a patchy lymphocytic and plasma cell infiltrate. There was no significant histiocytic atypia. Some of these histiocytes engulfed, without destroying, lymphocytes and neutrophils (emperipolesis). Immunohistochemical staining revealed that the histiocytes were strongly positive for S100 protein, weakly positive for CD68, and negative for CD1a. A diagnosis of CRDD was made. Oral prednisone therapy was initiated at a dosage of 30 mg/d for 3 weeks and then tapered over the ensuing 2 weeks. After 5 weeks of treatment, the lesions had markedly improved.

We report a 38-year-old man who presented with bilateral conjunctival congestion, hoarseness, and progressively growing pruritic, infiltrated skin lesions that had first begun over the face and neck, and later spread to the trunk and the limbs in 4 months. The clinical appearance of the lesions mimics granulomatous rosacea, acne vulgaris, or pityrosporum folliculitis. Histopathologic examination of the lesions from the face and chest both revealed dense dermal nodular lymphohistiocytic infiltrates which were positive for CD68 and S-100, but negative for CD1a. A systemic work-up for him detected no lymphadenopathy or other systemic involvement. A diagnosis of extranodal Rosai-Dorfman disease was made, and the patient received systemic glucocorticoids, with considerable improvement after 4 months of therapy.
