Bilateral breast involvement in Sézary syndrome.
Cutaneous T-cell lymphoma is a term used for mycosis fungoides and Sézary syndrome, the distinct clinical entities where the skin is the primary organ of involvement. Sézary syndrome is the leukemic variant of mycosis fungoides, presenting with generalized erythroderma, lymphadenopathy, and atypical cells (the Sézary cells) in the peripheral blood and bone marrow. The dissemination of cutaneous T-cell lymphoma may occur with no exception of the organs; however, no prior report exists about the Sézary syndrome secondarily involving the breasts. We report the clinical and radiological findings of bilateral breast involvement in a case of Sézary syndrome.
