We reported a 59-year-old woman who received a diagnosis of psoriasis vulgaris at the age of 35 and had been under medical treatment. She was admitted to our department on August 16, 1993 because of lymphadenopathy, arthralgia and neuralgia. We observed cervical and axillar lymphadenopathy 1-3 cm in diameter, anemia and leukothrombocytosis. Elevated levels of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and immunoglobulin G (IgG), but not M-protein were observed by immunological analysis of the serum. Bone marrow aspiration biopsy revealed hypercellularity with myeloid hyperplasia and slight increase in plasma cells. Elevated levels of serum interleukin-6 (IL-6) and granulocyte colony-stimulating factor (G-CSF) were detected; IL-6 was 62.1 pg/ml and G-CSF was 66 pg/ml, but IL-1 alpha, IL-1 beta and TNF-alpha were within the normal range. Idiopathic plasmacytic lymphadenopathy (IPL) with polyclonal hyperimmunoglobulinemia was diagnosed by lymph-node biopsy and the patient received following treatment with prednisolone and hydroxyurea. Leukocytes, platelets and skin eruptions increased again when the steroid dose was tapered, so we changed treatments to MP (melphalan, prednisolone) therapy. In addition, various neurological abnormalities such as convulsions, loss of consciousness and peripheral polyneuritis were observed. Despite treatment her condition deteriorated and she finally died. Very few reports show these neurological abnormalities in IPL or Castleman's disease therefore we think this is a very rare case.

Idiopathic plasmacytic lymphadenopathy (IPL) with polyclonal hyperimmunoglobulinemia is considered identical to multicentric Castleman's disease (MCD) reported in western countries. Clinically, both IPL and MCD are characterized by multicentric lymphadenopathy, prominent polyclonal hypergammaglobulinemia, elevated erythrocyte sedimentation rate, elevated serum interleukin-6 concentration, bone marrow plasmacytosis, and various abnormal laboratory data such as anemia and positive autoantibodies. However, IPL has a significantly better 5-year survival rate than that of MCD. Moreover, none of the present 16 cases developed Kaposi's sarcoma or B-cell lymphoma. Histologically, the interfollicular area contains a sheet of polytypic mature plasma cells in both IPL and MCD. In MCD, the majority of lymphoid follicles had hyaline-vascular germinal centers. However, lymphoid follicles of IPL usually exhibit a hyperplastic germinal center. Immunostaining also demonstrated a normal/reactive follicular dendritic cell network pattern in the germinal center of IPL. Moreover, there were no human herpes virus-8-positive cells detected by immunohistochemistry. The overall clinicopathologic and immunohistochemical findings of our 16 cases suggest that IPL is distinct from MCD reported in Western countries.

Idiopathic plasmacytic lymphadenopathy (IPL) with polyclonal hypergammaglobulinemia has been proposed as a new disease entity resembling the plasma cell type of multicentric Castleman's disease. Here, we report a case of IPL accompanied by renal failure and skin involvement. A 35-year-old man was admitted for advanced renal failure, anemia, systemic lymphadenopathy and skin rashes. Laboratory examinations indicated polyclonal hypergammaglobulinemia and elevated serum interleukin-6 (IL-6). Biopsy of a cervical lymph node revealed follicular hyperplasia with normal germinal centers, sheets of polyclonal proliferating plasma cells and the absence of marked proliferation of blood vessels in the interfollicular area. Lesions of the kidney and skin also had pathological characteristics of IPL. Following a diagnosis of IPL, corticosteroid therapy successfully improved the anemia and hypergammaglobulinemia, and serum IL-6 levels decreased to a normal range. This case may give suggestions about diagnosing and preventing the progression of complications from this disease entity.
