T-cell lymphoma with POEMS syndrome.

Angioimmunoblastic T-cell lymphoma (AITL) is a unique subtype of peripheral T-cell lymphoma. POEMS syndrome is a rare paraneoplastic syndrome caused by an underlying plasma cell disorder (PCD). The occurrence of AITL with POEMS syndrome has rarely been reported in the literature. The current study presents the case of a 53-year-old male who presented with a rapidly proliferative lymph node on the left neck, which was identified as an AITL on biopsy. The patient also exhibited the complications of polyneuropathy, M-proteinemia, hepatosplenomegaly, left ventricular hypertrophy, endocrinopathy and skin changes, and was therefore diagnosed with POEMS syndrome. To the best of our knowledge, the present study is the first to report a case of AITL with POEMS syndrome. The findings in this case suggest that the aberrant clones of B cells can also be caused by AITL.
