Subcutaneous panniculitis‐like T‐cell lymphoma with extracutaneous dissemination demonstrated on FDG PET/CT

A 24-year-old male presented with a 2-month history of painless subcutaneous nodules on his trunk and limbs, associated with night sweats, fatigue, and malaise. On examination, there were widespread palpable subcutaneous lesions with an average diameter of 2–3 cm. There was no palpable lymphadenopathy or organomegaly. Peripheral blood count showed a mild neutropenia and anemia: hemoglobin 12.3 g/dL, platelet count 146 3 10/L, neutrophils 1.2 3 10/L, lymphocytes 0.7 3 10/L. His lactate dehydrogenase and beta-2-microglobulin were elevated. He had a reduced immunoglobulin A level but no monoclonal band was demonstrated on serum protein electrophoresis. A skin biopsy showed an atypical small-to-medium-sized lymphoid infiltrate with typical panniculitic pattern involving This article was published online on 9 November 2010.
