Platelet-type von Willebrand disease (PT-vWD) is an autosomal dominant bleeding disorder characterized by abnormally enhanced binding of von Willebrand factor (vWF) by patient platelets. Although the platelet glycoprotein (GP) Ib/IX complex is known to constitute the platelet's ristocetin-dependent receptor for vWF, a unique structural abnormality within(More)
The majority of patients with idiopathic thrombocytopenic purpura (ITP) have antiplatelet autoantibodies that are most frequently directed against platelet glycoproteins IIb/IIIa or Ib/IX/V. However, there is some debate whether the immune response is oligoclonal or polyclonal in nature. We investigated the subclass distribution of anti-IIb/IIIa IgG(More)
Decreased von Willebrand factor (VWF)-cleaving protease activity (<5%) has been implicated in patients with congenital thrombotic thrombocytopenic purpura-hemolytic uremic syndrome (Upshaw-Schulman syndrome) and associated with mutations within the ADAMTS13 gene. In this report, we describe longitudinal studies in a patient with congenital TTP who(More)
INTRODUCTION Burkitt-like lymphoma (BLL) is a provisional category of B-cell lymphoma which is morphologically intermediate between Burkitt lymphoma (BL) and large B-cell lymphoma (LBCL). The clinical significance of this morphology is controversial. PATIENTS AND METHODS We examined 41 cases of pediatric B-cell lymphoma by immunohistochemistry for(More)
Primary nodal marginal zone B-cell lymphoma is an uncommon monoclonal B-cell lymphoproliferative disorder. We report a case of a 79-year-old woman who presented with generalized lymphadenopathy. Histologic and immunohistochemical examinations of biopsy sections from an axillary lymph node were consistent with nodal marginal zone B-cell lymphoma. Flow(More)
The underlying molecular basis for Bernard-Soulier Disease (BSD) is currently unknown. Platelets from patients with this autosomal recessive bleeding disorder have multiple abnormalities, including a markedly reduced von Willebrand factor-dependent adhesiveness due to a deficiency of the platelet membrane glycoprotein (GP) Ib/IX complex. In the present(More)
