Persistent Polyclonal B-cell Lymphocytosis

PPBL

Evaluating a splenectomy sample in cases like this may present a diagnostic challenge to pathologists. [ncbi.nlm.nih.gov]

RESULTS: PPBL presents in the majority of cases with persistent polyclonal B-cell lymphocytosis and affects primarily smoker women. [idibgi.org]

We also present here a literature review on pathogenesis of PPBL. [thescholarship.ecu.edu]

  • Splenomegaly

    Significant symptomatic splenomegaly requiring splenectomy is very unusual for this disorder; therefore there is a lack of descriptions of the morphologic features of the spleen in the literature. [ncbi.nlm.nih.gov]

  • Massive Splenomegaly

    We present here one of the first detailed descriptions of the morphologic and immunohistochemical features of the spleen from a young female with PPBL who developed massive splenomegaly during 6-year follow up. [ncbi.nlm.nih.gov]

    Massive splenomegaly is rare among these patients. Our PPBL patient reported here manifested slowly progressive splenomegaly during six years of follow-up. [diagnosticpathology.biomedcentral.com]
