Rare presentation of secondary cutaneous involvement by splenic marginal zone lymphoma: report of a case and review of the literature.

Cutaneous lymphomas encompass a broad spectrum of malignancies, including both primary and secondary cutaneous lymphomas. Determining the exact subtype of cutaneous lymphoma offers prognostic importance and directs therapeutic decisions. We describe the case of a 67-year-old woman with cutaneous involvement of splenic marginal zone lymphoma successfully treated with rituximab and bendamustine. We discuss the diagnostic work-up, including the histopathologic findings and treatment of this disease.
