Chronic neutrophilic leukemia is a rare, infrequently recognized, myeloproliferative disorder. It usually manifests as a leukemoid reaction, with mostly mature granulocytes in the peripheral blood, with rare to occasional immature forms, and sometimes with normoblasts. The clinical manifestations also include hepatosplenomegaly, elevated leukocytic alkaline phosphatase, elevated serum vitamin B12 and serum vitamin B12 binder ("R" fraction), and elevated serum uric acid. Distinction from a leukemegaly, the absence of sepsis, usually normal erythrocytic sedimentation, and the absence of fever. Leukemoid reactions may be associated with elevated serum vitamin B12 and uric acid, but the levels are usually lower than those found in chronic neutrophilic leukemia. Many patients have gouty symptoms, especially after treatment with Busulfan, and many have an unexplained hemorrhagic tendency, making major operations a risk. The authors add two cases to the 11 previously described.

Brucellosis has always been an unusual disease in children and, concomitant with the control of the disease in domestic animals, reports have become sparse. The pediatrician, therefore, may not be aware of the protean clinical manifestations of childhood brucellosis. In 1973, nine cases occurred during a three-month period in El Paso, Texas. All cases were marked by spiking fevers and lethargy of four days to four weeks in duration. Tender hepatomegaly or splenomegaly was striking in seven patients. Other characteristics included epistaxis, arthralgia, myalgia, and weight loss. Leukopenia and leukemoid reaction were found in five patients. All of the patients tested had elevated liver enzymes. Febrile agglutinins were invaluable in screening for an early clue to diagnosis. When Brucella abortus antigen agglutinated serum from patients with a positive screen in dilutions greater than 1:320, a presumptive diagnosis of brucellosis was made. Brucella was isolated from the blood or bone marrow in seven patients and the time of incubation proved crucial for successful recovery. Bacterial blood cultures are usually discarded at ten days of age, as were cultures from the only two patients from whom the organism was not recovered. All of the cultures incubated for 12 to 15 days grew B. melitensis, an unusual causative species in the United States. However, several patients admitted eating cheese from the State of Chihuahua, Mexico, made from unpasteurized goat's milk, the presumed source of the infection. Within one to three days, all patients responded dramatically to antibiotics; tetracycline was given orally for 21 days and streptomycin intramuscularly for 14 days. Pediatricians caring for patients in areas where consumption of unpasteurized milk products is likely would do well to consider brucellosis in a child with obscure fever or toxic hepatosplenomegaly.

An inappropriate, sustained and absolute lymphocytosis in a young man was investigated using technics which attempted to define the more detailed features of these cells and their T and B subpopulations. The results of the tests for lymphocyte RFC (E) and complement (EAC) rosette formation, immunofluorescence, in vitro phytohemagglutin (PHA) stimulation and 14C-cyclo-phosphamide binding assays, when evaluated in a combined and interrelated fashion, indicated that the lymphocytosis was mainly but not solely, due to an absolute elevation in circulating T lymphocytes. Moreover, an aneuploid cell line with 47 chromosomes, presumably T cells, also was detected in PHA-stimulated cultures. These data, associated with the patient's anemia, lymphocyte-infiltrated bone marrow, hepatosplenomegaly, pharyngeal lymphoid tumor and the clonal proliferation of lymphocytes bearing an abnormal karyotype, furnish evidence that the lymphocytosis is more than an unremitting leukemoid reaction and is potentially neoplastic. The detection of the chromosomal abnormality at this patient's age and point in disease may make him especially unique in that he could be a clinical prototype for other patients with lymphoreticular tumors which remain undetected at their onset.

Two patients with chronic neutrophilic leukemia, a rare myeloproliferative syndrome, are reported with a review of the literature. The major features of the 34 collected cases (including the two patients reported here) were persistent leukocytosis simulating a leukemoid reaction, hepatosplenomegaly, hyperuricemia, increased vitamin B12 blood level, increased leukocyte alkaline phosphatase and absence of the Philadelphia chromosome. Infection was the leading cause of death. Concomitant multiple myeloma was found in eight patients.

We report here a case of right-sided renal cell carcinoma who presented with hypertension and multi-organ metastases. Haematological manifestations noted were erythrocytosis, thrombocytosis and leukaemoid reaction. Of these leukemoid reaction and thrombocytosis are very rare. The patient had hepatosplenomegaly which was found to be congestive in origin due to the pressure of the tumour on the hepatic vein and the inferior vena cava. These rare features make it an unusual case.

Chronic neutrophilic leukemia (CNL) is a rare type of leukemia. We diagnosed a 81-year-old woman as CNL because she showed that sustained leukocytosis dominated by mature neutrophils, hepatosplenomegaly, high neutrophilic alkaline phosphatase (NAP) score, absence of the Ph1 chromosome and no evidence of leukemoid reaction. During the clinical course, she did not manifest hemorrhagic tendency or infection. We also examined neutrophilic function including chemotaxis, chemiluminescence, nitroblue tetrazolium (NBT) dye reduction, which all indicated normal neutrophil function. Using a reversed phase-high pressure liquid chromatography (HPLC), we detected the production of leukotriene B4 (LTB4) in neutrophils. We found that the LTB4 production was decreased in neutrophils whereas they showed normal chemotaxis. This discrepancy has never, to our knowledge, been reported before in case of CNL.

A case of lepromatous leprosy with erythema nodosum leprosum (ENL) presenting as a myeloid leukemoid reaction is reported. Very high leucocyte count with immaturity of the cells in myeloid series was present in peripheral blood. High leucocyte alkaline phosphatase score, absence of hepatosplenomegaly and transient nature of leukemoid reaction differentiated it from chronic myeloid leukemia and acute myeloblastic leukemia. The possible mechanisms of leukemoid reaction in ENL are discussed.

A female newborn was delivered prematurely at gestational age of 26 weeks with birth weight of 1,000 grams. Her initial white blood cell count was 68,900/mm3, which increased to 207,000/mm3 on the fifth day of life with a remarkable shift-to-left pattern. The most immature myeloid series in the peripheral blood smear was promyelocyte; and the promyelocyte, myelocyte and meta-myelocyte accounted for 38% of the peripheral white blood cells. Neither hepatosplenomegaly nor skin rash was noted, but the platelet count dropped to 86,000/mm3 transiently on Day 8. Cytogenetic study for the bone marrow aspiration revealed normal results. The leukemoid reaction recovered within three weeks without specific treatment. Antenatal usage of steroid to promote lung maturation was considered to be one possible cause of the transient leukemoid reaction.

A 30-year-old man with chronic neutrophilic leukemia (CNL) in association with monoclonal gammopathy is presented. Physical examination on admission revealed moderate hepatosplenomegaly. Initial blood count showed neutrophilic leukocytosis (42.2 x 10(9)/1 with 90% mature neutrophils). Leukocyte alkaline phosphatase (LAP) score was elevated. Bone marrow aspiration showed myeloid hyperplasia without dysplastic features. Karyotypic and molecular analyses of bone marrow cells showed the absence of Philadelphia (Ph1) chromosome and bcr gene rearrangement. Because there was no underlying infection or neoplasm, he was diagnosed as having CNL associated with IgG kappa-type monoclonal gammopathy (IgG, 1,269 mg/dl). In addition to its association with monoclonal gammopathy of undetermined significance (MGUS), the present case was also characterized by spontaneous remission of CNL during the 12-year follow-up, accompanied by a gradual increase in serum IgG levels up to 3,000 mg/dl. As far as we know, there have been 19 cases of CNL associated with monoclonal gammopathy in the literature. The median survival of these cases was 5 years. Although there have been only 6 cases of CNL associated with MGUS, survival of these cases was particularly favorable. Taken together with the observation that leukocytosis and hepatosplenomegaly in the present case subsided without specific treatment, we speculate that myeloid proliferation in the present case may have been a leukemoid reaction to underlying monoclonal gammopathy.

Chronic neutrophilic leukemia is a rare hematological disorder with hepatosplenomegaly and sustained mature neutrophilic leucocytosis. Increased serum vitamin B12, increased serum urine acid levels and increased leukocyte alkaline phosphatase activity are the associated features in the absence of fever or any other underlying disorder to cause leukemoid reaction. We report one such rare case.
