Disseminated anetoderma in a patient with nodal Epstein-Barr virus-associated classical Hodgkin lymphoma: Anetodermic form of a concurrent discordant cutaneous marginal zone lymphoma.

Patients with a lymphoma have an increased risk of developing a second lymphoproliferative disorder. The association of nodal Hodgkin lymphoma and primary cutaneous marginal zone lymphoma (MALT type) is exceptional, and only very few cases have been documented. Anetoderma represents a circumscribed loss or rarefication of elastic fibers. Different underlying processes may result in anetoderma, including cutaneous marginal zone lymphoma. We report a 50-year-old male patient with Epstein-Barr virus (EBV)-associated nodal Hodgkin lymphoma who presented with disseminated anetodermic skin lesions. Biopsies of the skin lesions revealed a B-cell infiltrate containing monoclonal plasma cells but without detection of EBV. The skin lesions represent an anetodermic form of primary cutaneous marginal zone lymphoma. It is the first case report of an association of anetodermic cutaneous marginal zone lymphoma and a synchronous EBV-associated nodal Hodgkin lymphoma.
