Abstract
Background:
Cutaneous xanthomas develop as a result of intracellular and dermal deposition of lipids in either hyper- or normolipidemic patients. Plane xanthomas may signal the presence of an underlying monoclonal gammopathy, chronic myelomonocytic leukemia, or cutaneous T-cell lymphoma. Investigators have suggested that xanthomatized T cells may result in induction of plane xanthomas.
Methods:
We report the case of a patient with mycosis fungoides (MF) and plane xanthomas who was treated with bexarotene for his MF.
Results:
Significant improvement in the clinical signs of MF was observed within 3 months. We also observed a substantial regression of the xanthomas after 5 months of treatment. Complete clinical remission of both the MF and xanthomas was obtained after 6 months. The patient was still free of xanthomas after 3 years of follow-up.
Conclusion:
Bexarotene led to the clearing of the cutaneous lesions of cutaneous T-cell lymphoma and plane xanthomas. This may be due to an effect of bexarotene on the aberrant T cells that may cause xanthomatization.
