An autopsy case of systemic histiocytosis with excessive deposition of kappa-type light chain crystals was reported in a 58 year-old man who had consistently showed kappa-type light chain paraproteinemia, Bence Jones proteinuria and hypogammaglobulinemia for about 10 years until his death. However, no bony destruction was found by repeated X-ray examinations. At autopsy, extensive hyperplasia of crystal-storing histiocytes was observed in the bone marrow, spleen, liver, lymph nodes, interstitial tissues of visceral organs and loose connective tissues. In the bone marrow and some other tissues, mild proliferation of plasmocytoid cells containing small crystals were found. Histochemically the crystals positively stained with various methods for amino acids and proteins, especially with Weigerts' method for fibrin. Ultrastructurally intralysosomal crystal deposition was confirmed in the storage histiocytes and derivation of the crystals from Golgi's sacculi in the plasmocytoid cells was suggested. Biochemically the crystals were regarded as mainly consisting of dimers of a variable half of light chain immunoglobulin and immunochemically and immunohistochemically reacted to anti-kappa type light chain serum. Such a generalized storage histiocytosis may be secondarily induced by immunoglobulin synthesized in plasmocytoid cells.

A review of 869 cases of multiple myeloma seen at the Mayo Clinic from 1960 through 1971 revealed that 98% of patients were 40 years of age or older and that 61% of them were males. Inital findings were bone pain in 68% of patients, anemia in 62%, renal insufficiency in 55%, hypercalcemia in 30%, a palpable liver in 21%, and a palpable spleen in 5%. Proteinuria was noted in 88% and Bence Jones proteinuria was identified in 49%. Skeletal roentgenographic abnormalities were seen in 79%. Serum protein electrophoresis showed a spike in 76%, hypogammaglobulinemia in 9%, and minor or no abnormalities in 15%, and a globulin spike was seen 75% of the urinary electrophoretic patterns. Immunoelectrophoresis of the serum revealed a monoclonal heavy chain in 83% and a monoclonal light chain in the serum, in 8% (Bence Jones proteinemia). Three patients had no monoclonal protein in the serum or the urine ("nonsecretory"). Amyloidosis was found in 7% of the patients. Follow-up information was obtained in 99.7% ; 82% of the 869 patients have died. Infection and renal insufficiency were the most common specific causes of death. The median survival was 20 months; 66% of the patients were alive at 1 year and 18% at 5 years.

A small number of human myelomas have been established as long term cultured cell lines. We report the characteristics of two new cell lines, designated SK-MM-1 and SK-MM-2, derived from 73 attempts to culture myeloma specimens. Both cell lines were grown from myeloma patients with hypogammaglobulinemia, kappa light chain proteinuria, and plasma cell leukemia. SK-MM-1 and SK-MM-2 had a plasmacytoid morphology, grew in RPMI complete medium with doubling times of 32 and 60 hr, respectively, and did not express Epstein-Barr virus nuclear antigen. Both cell lines secreted kappa light chains (0.9 and 1.1 micrograms/10(6) cells/ml per 48 hr for SK-MM-1 and SK-MM-2, respectively) but no heavy chains. SK-MM-1 and SK-MM-2 expressed the pan-B cell marker B1 and the late B cell/plasma cell marker BL3. In addition, SK-MM-2 expressed late B cell/plasma cell markers OKT10 and PCA-1. Neither cell line expressed T lymphocyte, myeloid, or early B lymphocyte markers. The presence of distinctive kappa and heavy chain gene rearrangements supported the clonal origin of both cell lines from kappa light chain-producing B cells. The two cell lines were markedly aneuploid and both carried a 14q+ marker chromosome. Human myeloma cell lines lacking heavy chain secretion may be useful to elucidate mechanisms of immunoglobulin gene regulation and to construct human-human hybridomas.

Pyoderma gangrenosum (PG) is a rare condition remarkable for its association with particular diseases, notably haemopathies and gastrointestinal diseases. As regards haemopathies, the associations most frequently encountered are with myeloid malignancies and monoclonal dysglobulinaemia. The association of PG with mainly inflammatory digestive tract diseases is also classical. The lack of publications concerning gastric atrophy and the dual haematological and gastric pathology which characterizes our case have prompted us to report it. A 60-year-old woman without significant history was admitted for PG on both knees, following vesiculo-bullous lesions. Laboratory examinations detected a normochromic anaemia tending to be macrocytic, a marked inflammatory syndrome and a monoclonal lambda light chain IgA peak at protein immunoelectrophoresis. Bone marrow biopsy, skeletal radiography and a search for Bence-Jones proteinuria were normal or negative. Colonoscopy showed no abnormality, but fibroscopy of the upper digestive tract revealed a severe gastric atrophy en plaques. Serum vitamin B12 level was moderately low, but there was no other sign of pernicious anaemia. After one month treatment with systemic corticosteroids, healing was obtained under replacement vitamin therapy. PG recurred a few months later; serum vitamin B12 level was normal, and the lesions healed after systemic corticosteroid treatment. In non-myelomatous dysglobulinaemia IgA is frequently found and there is no light chain predominance. PG often precedes dysglobulinaemia. Evolution towards a true myeloma seems to be exceptional. In a recent publication, 17 cases of association between PG and myeloma were mentioned, the IgA type being most common. Protein electrophoresis is indispensable in patients with PG. Five cases of congenital hypogammaglobulinaemia have been recorded, including three with IgA deficiency.(ABSTRACT TRUNCATED AT 250 WORDS)

Two Chinese infants with asymmetrical lymphoedema and steatorrhoea were investigated. The laboratory investigations showed that they had hypoproteinaemia without proteinuria. One of them showed peripheral lymphopenia and hypogammaglobulinaemia. Radiologically, they had evidence of extensive lymphangiectasia of the small intestine. This was confirmed histologically. Endoscopy of one of them showed diffuse milky nodular duodenal mucosa. The appearance of the mucosa was rather typical of intestinal lymphangiectasia.

Chyluria is the passage of chylus into urine resulting in fistulization through the lymphatic system and the urinary system. This rare condition is usually caused by filaria infestation or malformations, neoplasia or trauma. We report a case of a 18-year-old man. The patient presented milky urine which had appeared after angiography following minor leg trauma. Physical examination revealed asymmetry of the face and cutaneous dyschromia. Blood tests revealed hypogammaglobulinemia and altered CD4/CD8 ratio (0.6). Urine tests showed proteinuria (30 mg/dl), lipiduria (triglycerides 750 mg/dl) and density of 1025. Renal function was normal. Abdomen computed tomography and urography were normal. Cystoscopy revealed the presence of milky urine in the bladder and selective catheterization revealed that the origin was the right ureter alone. Ascendent pyelography did not reveal any malformation of the urinary tract; but after this the chyluria spontaneously disappeared. The patient was rehospitalized 3 months later for recurrence. Lymphography was then performed and revealed a dilated lymphatic network with minute lacunar images projecting into the right kidney. Chyluria again disappeared spontaneously and recurred sporadically over the next two years in a patient who remained in good physical condition. The etiology of chyluria in a patient without filaria infestation is problematic, particularly when the most common causes (tuberculosis, neoplasia, trauma) are excluded as in our case. The asymmetry of the face, together with cutaneous dyschromia and the presence of a subarachnoidea cyst in the right temporal region suggested our patient had multiple congenital malformations.

The incidence of multiple myeloma is lower in Southeast Asia than in the West. However, there are few reports on the overall incidence of paraproteinemia and its disease-associations in the Chinese. Therefore, the authors have correlated the laboratory features with the eventual clinical diagnosis in patients with paraproteinemia in a Hong Kong general/teaching hospital. Over 18 months, 1,600 patients were investigated for the presence of paraproteinemia. Paraproteinemia was detected in 157 (10%) patients. In 11 patients, investigations could not be completed. The remaining 146 patients were subjected to detailed clinical, radiologic, and laboratory investigations. Eighty-seven (59.6%) had monoclonal gammopathy of unknown significance (MGUS), 44 (30.1%) myeloma and 15 (10.3%) other lymphoproliferative disorder (LPD). There was no significant difference in the paraprotein concentration, frequency of hypogammaglobulinemia of Bence Jones proteinuria (BJP) or concentration of nonparaprotein immunoglobulin (Ig) between the myeloma and LPD groups. The overall kappa:lambda light chains ratios were 2.9, 1.6 and 3.3 in the MGUS, MM and LPD groups, respectively. Polyclonal Ig elevation was rare with myeloma (4.5%) but was detected in 33% of patients with LPD (P < .02) and 40% of those with MGUS (P < .0001). Biclonal (and one triclonal) gammopathy was detected in 11.5% of patients with MGUS, 11% with LPD and 4.5% with myeloma. In the MGUS group, infection was the commonest associated clinical disorder (29.3%). Moreover, 70% of patients with biclonal gammopathy and MGUS had an infection. Five of 15 patients with LPD had a T-cell malignancy, including 3 lymphomas and 2 large granular cell leukemias. Only one patient had primary systemic amyloidosis. It is concluded that the high frequency of biclonality and its association with infection, of paraproteinemia in association with T-cell malignancy and of kappa light chains in the MGUS and LPD groups are at variance with reports from the West and probably reflect local differences.

Secondary amyloidosis without a known cause, diagnosed antemortem in a patient with idiopathic myelofibrosis, is reported here. This is the first such case, to our knowledge. Amyloid deposits were seen in the bone marrow, renal glomeruli and jejunum. Reasons for investigating for amyloidosis were hypogammaglobulinemia, proteinuria and recurrent diarrhea.

Pericardial involvement is a rare complication of multiple myeloma, caused by amyloidosis, infections, or plasmacell infiltration, usually at late or terminal disease stage. We report a patient with pericarditis coming from a department of Cardiology where a preceding (15 years before) diagnosis of breast cancer and present bloody pericardial effusion with probably malignant cells permitted at first to orientate towards metastatic pericardial involvement in breast cancer. Laboratory findings (pancytopenia, hypogammaglobulinemia, proteinuria) suggested to perform bone marrow aspirate, serum and concentrated urine immunoelectrophoresis, measurement of 24-h urine protein excretion, and further cytologic and immunocytochemical assay of pericardial fluid. Acquired data allowed to diagnose light chain multiple myeloma with pericardial involvement caused by plasmacell infiltration. We diagnosed this complication, representing first and main clinical feature of multiple myeloma, owing to a complete clinical and laboratory evaluation and repetition of cytologic and immunocytochemical assay of pericardial fluid.

A boy aged 4 years with nephrotic syndrome (NS) was referred to our hospital because of the third relapse of NS. Hypogammaglobulinemia associated with massive proteinuria was observed at the presentation. Residual urinary tract infection required intravenous piperacillin and immunoglobulin therapy (IVIG). Soon after IVIG, he complained of high fever with chills, bilateral knee joint pain, dry cough and chest discomfort. Although he did not develop renal insufficiency, a transient increase in the urinary beta2-microglobulin and decrease in the serum complement hemolytic activity were observed. These clinical manifestations spontaneously ceased. A percutaneous renal biopsy for his NS performed 19 days after the episode of allergic reaction revealed tubulointerstitial nephritis (TIN) with marked eosinophil infiltrates. Glomeruli showed minor glomerular abnormalities. Renal complications associated with IVIG treatment have been reported to date, however, acute TIN has rarely been seen.
