Background: Xanthoma disseminatum is a rare non-familial disease characterized by lipid deposition in skin and internal organs due to histiocytic cell proliferation, classified as a benign non-Langerhans cell histiocytosis. This chronic disease has no known established treatment. We report 8 cases of xanthoma disseminatum with treatment outcomes in long-term follow-up and provide a review of the medical literature. Observations: We studied clinical manifestations; disease course; histopathologic and immunopathological findings; and responses to treatment in 8 consecutively seen patients with xanthoma disseminatum, including follow-up. The follow-up period ranged from 3 months to 8 years. Five patients received 2-chlorodeoxyadenosine. Therapy with 2-chlorodeoxyadenosine was effective at inducing remission and long-term control of cutaneous lesions of xanthoma disseminatum in 5 cases. Adverse effects were minimal, and treatment was well tolerated. No improvement was noted in untreated patients. Conclusion: Among 8 cases of xanthoma disseminatum, a positive response to treatment with 2-chlorodeoxyadenosine was seen in 5 cases.
