We have investigated the incidence and significance of abdominal lymphadenopathy in hairy cell leukemia (HCL) by routinely CT scanning 88 patients. These included 70 men and 18 women with a median age of 51 years (range 25-83). Abdominal CT scans were performed at diagnosis in 29 patients and in 59 during the course of the disease. Abdominal lymphadenopathy was documented in 25 patients (28%) overall; the incidence of abdominal lymphadenopathy was higher in relapse (56%) than at diagnosis (17%). All patients with lymphadenopathy had bone marrow disease. There is no association with age or sex but lymphadenopathy tends to be more common in patients with long-standing disease (median duration of disease 6 years v one year in those without nodes) and in patients with bulky disease, particularly in the relapse group (splenomegaly/splenectomy in 95% vs 40%). The presence of abdominal nodes is also associated with relative resistance to treatment, with more treatment failures and fewer complete responses seen in this group. Most patients with lymphadenopathy had large, immature-looking hairy cells present in both the bone marrow and lymph nodes, when these were examined. Abdominal lymphadenopathy in HCL is more common than previously recognised, particularly in relapsed patients, and is always associated with active disease. The presence of large hairy cells and the relative resistance to treatment suggest that this phenomenon represents a form of transformation of the disease. Longer follow up is required to confirm this.

A 58-year-old man was admitted in May 1988, because of high fever, skin, pigmentation and body weight loss. Abdominal ultrasonography and generalized computed tomography examinations showed swelling of general lymph nodes and bilateral adrenal glands, splenomegaly, and lesion in the liver. Serum cortisol, urinary 17-OHCS and 17-KS level were within the normal range, while the ACTH level was elevated (189.9 pg/ml). ACTH overload test showed a non-reactive pattern, leading to a diagnosis of partial Addison's disease. He was also diagnosed as non-Hodgkin lymphoma, diffuse, large cell type (B) by a biopsy of the left supraclavicular lymph node. After combination chemotherapy, swelling of the supraclavicular lymph node diminished, followed by normalization of ACTH level and improvement of symptoms. Abdominal lymphadenopathy, hepatosplenomegaly and swelling of adrenal glands also decreased in size. Although involvement of tumor cells in adrenal glands sometimes occurs in malignant lymphoma, it is reported that more than 90% destruction of adrenal gland tissue is necessary to develop Addison's disease. It was suggested that the involvement of many lymphoma cells in both adrenal glands resulted in the development of partial Addison's disease in this case.

We describe an 89-year-old woman who presented with prominent plasmacytosis mimicking plasma cell leukemia. The apparent serum M-protein level of > 7 g/dL of gamma mobility was revealed to be a polyclonal increase of immunoglobulins. The plasma cells in the peripheral blood expressed polyclonal surface/cytoplasmic immunoglobulins as well as CD19, CD30, CD38, and CD138 antigens but lacked CD10, CD20, CD25, and CD56. The bone marrow plasma cells showed the CD45+, CD19+, CD56-, MPC-1(-/+), and CD49e- immunophenotype, which was in clear contrast with the immunophenotypes of the neoplastic myeloma cells. Abdominal lymphadenopathy, splenomegaly, and a high level of soluble interleukin 2 receptor may have been reflections of an underlying lymphoproliferative disorder, potentially leading to the polyclonal proliferation of plasma cells.
