Presentation
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]
Physical examination was normal, especially no lymphadenopathy or hepatosplenomegaly were present. [ntvg.nl]
Entire Body System
- Splenectomy
Splenectomy was performed for symptomatic relief and suspicion of malignant process. [ncbi.nlm.nih.gov]
Transient decreases in IgM levels seen post-splenectomy return to pre-splenectomy levels by 4 years( 14 ). This phenomenon would not explain the low IgM seen in the patient described here in, as the splenectomy was more than a decade prior. [ispub.com]
This patient developed 2 years after splenectomy (13 years after PPBL diagnosis) a pulmonary diffuse large B cell lymphoma (DLBCL). [omicsonline.org]

Immune System
- 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]
Mild splenomegaly is the most frequently reported physical finding, which is detected in about 10% of patients according to the largest case series [ 2 ]. Massive splenomegaly is rare among these patients. [diagnosticpathology.biomedcentral.com]

Musculoskeletal

FISH studies using a chromosome 3 long arm-specific probe provided evidence that all cases had both +i(3)(q10) and +3. [ncbi.nlm.nih.gov]
Psychiatrical
- Suggestibility
An association with cigarette smoking was initially suggested. However PPBL was observed in non smokers patients. The morphology of binucleated lymphoid B-cells could suggest an association with viral infections, such as Epstein-Barr Virus. [atlasgeneticsoncology.org]
Suggestions for identifying the disorder are made. [ncbi.nlm.nih.gov]
Workup

HLA Type
- HLA-DR7
Other notable findings in this case are lack of HLA-DR7 and strong positive CD5 markers in the polyclonal B-cell population. [mayoclinic.pure.elsevier.com]
Persistent polyclonal B-cell lymphocytosis with binucleate lymphocytes is a rare lymphoproliferative syndrome of uncertain cause that is strongly associated with HLA-DR7 positivity, cigarette smoking, and female sex. [ncbi.nlm.nih.gov]
This recently identified distinct clinicopathologic entity is frequently associated with the presence of the HLA-DR7 antigen. It follows a benign course and has so far been reported only in women smokers. [serval.unil.ch]
