Abstract
Ki-1 (CD30) positive anaplastic large cell lymphoma (ALCL) is an uncommon, high-grade non-Hodgkin's lymphoma with distinct morphologic and immunohistochemical features. Solitary or multiple ulcerated nodules typically characterize cutaneous involvement. Erythroderma is very rare. We report the first case of primary nodal ALCL in which disease relapse manifested as generalized papules, nodules, and erythroderma. This unusual case expands the spectrum of cutaneous disease associated with Ki-1 positive ALCL and highlights the need for early biopsy in patients with a history of Ki-1 positive ALCL who have skin lesions develop.
