Intravascular B-cell lymphoma diagnosed by skin biopsy.

A 58-year-old man presented with unexplained fever, constitutional symptoms, worsening respiratory failure and gross, generalized oedema. He was eventually diagnosed with intravascular B- cell lymphoma on a random skin biopsy. Examination of the skin showed patchy erythema and induration, with peau d'orange. Despite multiorgan failure requiring intensive care, he responded dramatically to multiagent chemotherapy (six cycles of cyclophosphamide, doxorubicin, vincristine and prednisone) and is currently in clinical remission.
