[Pagetoid reticulosis in a patient with mycosis fungoides. Successful therapy with localized electron beam irradiation].

Pagetoid reticulosis is a mycosis fungoides subtype. It is characterized by a prominent epidermotropism, localized lesions, slow progression and benign prognosis. We report on a 67-year-old patient with a history of classic mycosis fungoides, who developed pagetoid reticulosis on the right heel. Local electron beam therapy induced a complete remission, with no recurrence over three months of follow-up.
