We have reviewed 15 cases of splenic abscesses diagnosed using a histopathological and microbiological study. Mean age was 48 years (range 18-78). Eight of them were male and 7 female. Eighty per cent of them had predisposing diseases, amongst which the most frequent were endocarditis and bacteriemia of other origin (26.6% in both cases). All patients presented fever and in 7 of them (47%) splenomegaly was appreciated. The most frequently isolated germs were gramnegative bacteria (33%), anaerobics (20%), and with a similar incidence grampositive bacteria, tuberculosis and fungii; in only one case cultures were sterile. Seven patients had multiple splenic abscesses and 8 patients single abscesses. Thorax x-ray showed alterations in more than half of the patients (53%). Abdominal echography was the diagnostic method in 67% of the patients and TAC in all the cases in which it was performed. Eight patients underwent splenectomy and one was surgically drained being the mortality rate of this group of 22%. Overall mortality was 33% and was related to the presence of multiple splenic abscesses (5/7, 71.4%), positive hemocultures (6/6, 100%), extrasplenic abscesses (7/8, 87.5%), and endocarditis (4/4, 100%), fungii infections (2/2, 100%), and late diagnosis (6/6, 100%).

We describe the clinical and laboratory features of 17 adult patients with a variant form of hairy cell leukemia (HCL-V) studied over the last 7 years. The main findings were: splenomegaly, moderate anemia, thrombocytopenia, and a raised white blood cell count (median 116 x 10(9)/L; range 15 to 482). The circulating lymphoid cells had abundant villous cytoplasm and a round, occasionally bilobed nucleus, with a prominent nucleolus. Monocytopenia, a feature of typical HCL, was not seen; neither was tartrate-resistant acid phosphatase demonstrated in eight cases tested. HCL-V cells had a mature B-cell phenotype: CD19+, CD20+, CD22+, FMC7+, CD11c+, CD10-, CD5-, with light chain isotope restriction in 15 cases. In contrast to typical hairy cells, HCL-V cells were negative with the monoclonal antibodies anti-HC2 and anti-TAC (CD25). Immunoglobulin (Ig) was not detected in two cases and IgG was expressed in the cell membrane of 73% of cases. Bone marrow histology was different from HCL, showing interstitial infiltration by cells clumped together and a moderate amount of reticulin, but the spleen showed the typical red pulp expansion of HCL. HCL-V patients did not respond to splenectomy (5 of 7) or alpha-interferon (7 of 7); 2 of 3 patients had a partial response to 2'deoxycoformycin. The clinical course was benign with 15 patients alive with a median survival greater than 4 years. We confirm that HCL-V is a distinct clinico-pathologic entity with intermediate features between HCL and B-prolymphocytic leukemia.
