Peripheral blood hemophagocytosis in an unusual lymphoma.

We describe a patient with fever, pancytopenia, and hepato-splenomegaly associated with the finding of neoplastic lymphoid cells and histiocytes with hemophagocytosis in the peripheral smear; the diagnostic features were suggestive for a biological overlap between a large B-cell lymphoma with intravascular involvement and the Asian variant of intravascular B-cell lymphoma.

Holotranscobalamin is a useful marker of vitamin B12 deficiency in alcoholics.

Background: Measurement of serum cobalamin (Cbl) levels is the standard investigation for assessing vitamin B12 deficiency. Falsely increased values of Cbl can be caused by alcoholic liver disease. Measurement of total vitamin B12 serum levels might be misleading in alcoholics, because a tissue metabolic deficiency is possible even with normal serum Cbl levels.

Whorled hairless nevus of the scalp, linear hyperpigmentation, and telangiectatic nevi of the lower limbs: a novel variant of the "phacomatosis complex".

The term "phacomatosis" refers to a growing number of sporadic genetic skin disorders characterized by the combination of two or more different nevi and possibly resulting from non-allelic twin spotting. While phacomatosis pigmentovascularis (PPV) and pigmentokeratotica represent the most common patterns, some patients do not fit with either condition and are temporarily classified as unique phenotypes. We report on an 8-year-old boy with striking right hemihypoplasia, resulting in limb asymmetry and fixed dislocation of right hip.

Multiplex ligation-dependent probe amplification and fluorescence in situ hybridization to detect chromosomal abnormalities in chronic lymphocytic leukemia: a comparative study.

Chronic lymphocytic leukemia (CLL) is a clinically heterogeneous disease characterized by recurrent chromosomal aberrations of prognostic significance. We aimed to evaluate the potential of the multiplex ligation-dependent probe amplification (MLPA) assay to detect genomic alterations in CLL. Highly purified (>90%) peripheral mononuclear CD19+ cell populations from 100 untreated CLL patients (pts) in early stage disease (Binet stage A) were included in this study.

Myocardial iron overload assessed by magnetic resonance imaging (MRI)T2* in multi-transfused patients with thalassemia and acquired anemias.

Background: Cardiac complications secondary to iron overload remain a significant matter in patients with transfusion dependent anemias.

Patients And Methods: To evaluate cardiac siderosis, Magnetic resonance imaging T2* (MRI T2*) was performed in 3 cohorts of transfusion dependent patients: 99 with thalassemia major (TM), 20 with thalassemia intermedia (TI), and 10 with acquired anemias (AA). Serum ferritin was measured and all patients underwent echocardiographic evaluation.
