title: Giant lymph node hyperplasia with osteoblastic bone lesions and the POEMS (Takatsuki's) syndrome.
abstract: A 38-year-old black man with giant lymph node hyperplasia (GLH), osteoblastic lesions, and the POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, M protein, skin changes) was treated at the University of Chicago Hospitals. The patient had hepatosplenomegaly and generalized peripheral lymphadenopathy. Endocrinologic abnormalities included decreased testosterone with elevated luteinizing hormone and follicle-stimulating hormone, as well as hyperprolactinemia and possible hypothyroidism. Biopsy of a right femoral lymph node revealed GLH, and an osteoblastic pelvic lesion showed a marked lymphoplasmacytic infiltrate. By immunohistochemical techniques, plasma cells in the lymph node and osteoblastic lesion were polyclonal. A polyclonal hypergammaglobulinemia was present. The lymph node T-lymphocyte population showed a decreased helper-to-suppressor cell ratio. Other findings included thickening of the skin, finger clubbing, and anasarca. A severe sensory-motor polyneuropathy was the major factor contributing to the patient's death. The association of GLH, osteoblastic bone lesions, and the POEMS syndrome has been noted previously in Japan; however, the authors are unaware of reports on Western patients who had this combination of clinical and laboratory findings.
