Development of lymph nodes that are histologically positive for tumor (stage IVA) and/or visceral lesions (stage IVB) may occur rather rapidly after tumor-stage disease develops and/or clinical lymphadenopathy is detected. Alternatively, either or both may arise from erythrodermic disease (stage III) at a very variable rate. Both are associated with a poor prognosis.
